OUTSTANDING STORM OF THE MONTH 

EF2 Tornado Kills One and Injures 11 in Rayne, Louisiana on the 5 th 

Numerous showers and thunderstorms developed across southeast Texas during the early 

morning hours on March 5, then spread eastward across southern Louisiana through the 

remainder of the morning. Some of these thunderstorms eventually became surface-based 

supercells, with one producing four tornadoes across Jefferson Davis and Acadia Parishes.

along Martin Luther King 

Boulevard in Rayne, Louisiana 

from the March 5, 2011 tornado. 

A NWS Storm Survey confirmed an EF2 Tornado touched down northwest of the Ebenezer 

Road/Standard Mill Road intersection southwest of Rayne and moved across the northern 

portion of the city, before ending near the community of Castille. A few outbuildings were 

destroyed in a small subdivision on Ebenezer Road and a few trees were blown down. The 

tornado crossed Highway 90 with no visible damage before striking the Rayne Water 

Treatment Plant west of town, completely destroying three metal buildings (EF2) and 

blowing debris over 200 yards to the east and northeast. The tornado then entered the main 

residential section of the city of Rayne at Marie Avenue and Lessley Street, demolishing two 

mobile homes and damaging several others (EF2). A patchwork of EF0/EF1 damage was 

noted to homes and trees as the storm moved across the northwestern part of Rayne. One 

woman was killed on Bella Avenue just north of West School Street when a large tree fell 

onto and flattened her small home. The tornado intensified as it neared and crossed Martin 

Luther King Boulevard, where two small homes and an abandoned two story building were 

leveled, and several duplexes lost their entire roofs (EF2). Crossing Highway 35, another 

duplex lost much of its roof as did an auto parts store. Several security cameras from nearby 

buildings filmed the tornado in this area. The storm weakened as it moved into northeastern 

Rayne, causing generally minor roof and exterior damage to the high school and adjacent 

stadium (EF1). EF0 damage was noted as the tornado crossed Interstate 10, with several pine 

trees snapped and minor damage to buildings. Minor damage continued to a few buildings on 

Nation Road and Highway 98 (EF0), with the final damage noted to a mobile home on 

Charlie Arceneaux Road. The City of Rayne Police Department confirmed a total of 1 fatality 

and 11 injuries. The Louisiana State Fire Marshal’s Office reported that 42 houses were 

destroyed, 48 sustained major damage, 79 houses suffered moderate damage, and another 514 

houses received minor damage, for a total of 683 damaged homes. Another unknown number 

of businesses were also damaged.

A stalled boundary sagged southward into North Central Alabama on Saturday, March 26, and became a focus for convection 

ahead of an approaching storm system. Through the day, as the air mass south of the boundary became increasingly unstable, 

thunderstorms developed across much of the area. This activity continued into the overnight hours. With the approach of a 

surface low and cold front, activity reintensified early Sunday morning, March 27, and continued through the pre-dawn hours 

on Monday as the cold front slowly moved through the area.

ALABAMA, North 

A surface low developed in Texas and moved into the northern Gulf of Mexico Tuesday evening, March 29th. Stable easterly 

flow across much of Central Alabama prevented a warm front from lifting northward and limited instability across the area. As 

the surface low tracked across the far southeastern portion of the forecast area, moderate rainfall fell across most of the area 

through Wednesday afternoon, March 30th. The lack of instability resulted in only an isolated severe threat from this storm 

system.

A swath of quarter sized hail fell south of Eudora. 

An area of low pressure over southeast Louisiana moved east along a warm front into southeast Mississippi through the period. 

This was followed by the passage of a strong cold front. This storm system triggered severe storms with scattered reports of 

hail and wind damage over central Mississippi and northeast Louisiana during the late afternoon and overnight hours. One 

report of large hail was received in extreme southeast Arkansas.

The month of March, 2011 remained on the dry side across most of the region. While the month did see some appreciable 

rainfall, it was not enough to stifle the ongoing drought conditions across the southern half of the state. By the end of the 

month, all of southern and southwest Arkansas was under D3 Extreme Drought conditions. The following are a few selected 

cities across Southwest Arkansas with their March rainfall totals and departures from normal as well as the 2011 rainfall totals

On March 10, a 9.1 earthquake off the west coast of Japan caused a tsunami that traveled across the Pacific Ocean in roughly 

ten hours. The first waves arrived on the coast of northern California around 9:30 a.m. on March 11 and continued for over 

three days. The largest amplitude wave arrived at approximately 10:30 a.m. on March 11 and measured approximately 8 feet in 

Crescent City, California. The maximum amplitude wave coincided with a relatively small 0.3 foot astronomical tide. This 

resulted in a total water depth of approximately 8.3 feet above mean sea level which did not inundate any land surface. The 

high velocity current associated with this maximum amplitude wave resulted in the majority of damage reported. The highest 

overall water height occurred at 2:00 a.m. the following morning when a 3 foot tsunami wave coincided with a 6 foot 

astronomical tide. The resultant overall water height of approximately 9 feet inundated a state highway but did not cause any 

damages. M25OU

On the 6th and 7th, a low pressure trough brought some rain and mountain snow to the area, but the main threat was strong and 

damaging winds in much of Kern County, including the desert and mountain areas. On the 6th, Bakersfield experienced gusty 

winds up to 35 mph as the cold front passed over the area. Wind gusts reached over 80 mph at some locations in the desert on 

the 7th. On this day, the winds were strongest during the morning and afternoon hours, when pressure gradients and upper level 

winds were most favorable. at 1130 AM a roof blew off a house just south of Weldon. A total of 5 semi truck trailers were 

blown over near Mojave and the intersection of Highways 58 and 14. At Edwards AFB, high winds caused damages to a house, 

car, and a garage. Also just to the west of Rosamond, several power poles were snapped and toppled due to the high winds. 

Winds subsided during the evening hours, but a few locations in the desert saw gusts continuing at 50-70 mph. By the 8th, 

temperatures remained several degrees cooler before then next ridge of high pressure strengthened over the area.

Dry conditions prevailed over the area through March 15th, with gusts of 45-60 mph at times in the mountain and desert areas 

of Kern County. The weather pattern then changed sharply, transitioning to a 12-day period which saw periods of heavy 

precipitation and below normal temperatures. 

From the evening of the 15th until the afternoon of the 16th, a storm system passed over the area, bringing precipitation mainly 

to the mountains and foothills, but light amounts did fall on the San Joaquin Valley floor. Most of the precipitation fell mainly 

as rain over the Southern Sierra Nevada in the northern part of WFO San Joaquin Valley-Hanfordâs forecast/warning area. The 

highest amounts, which occurred in Yosemite National Park, ranged from about 1.5 to 3 inches; this was the most precipitation 

that had occurred in the region for the month thus far. However, this was just the harbinger of what was to come only 4 days 

later. 

While the rain was focused toward the north, winds were the main concern over the southern part of the region. The Kern 

County deserts saw gusts of 45-55 mph, and gusts as high as 66 mph were recorded in the Kern County mountains. The winds 

pushed clouds over the San Joaquin Valley into the Tehachapi Mountains, creating areas of dense fog. Visibilities as low as 100 

feet were reported near Tehachapi. 

The next storm arrived two days later. This was a two-part system, with the first part bringing between a tenth and a third of an 

inch of rain to the central and southern San Joaquin Valley. The first wave also brought a very cold airmass to the region. A 

foot of snow fell at Hetch Hetchy, and 10 inches of snow fell as far south as Lodgepole in Sequoia National Park. Snow even 

fell in the foothills, with 5 inches falling at Mid Pines at an elevation of 2400 feet. The main part of the storm arrived on the 

20th, bringing record rain to both Bakersfield and Fresno, the latter city recording 1.82 inch of rain. In the Southern Sierra 

Nevada, there was no break in the snow, as upslope showers continued through the 19th until the second wave arrived. 

Another foot of snow fell as far south as Fresno County on the 19th, and 4-5 inches in Tulare County. 

Strong winds developed ahead of the main storm, with gusts up to 84 mph in the hills above the Grapevine during the night of 

March 19th-20th, and gusts up to 60 mph at the lower elevations from Frazier Park to the base of the Grapevine. 

The winds spread as far north as Bakersfield during the early morning of the 20th, and continued spreading north through the 

day. The heavy rains caused some road flooding on the San Joaquin Valley floor, as well as on Interstate 5 north of Fort Tejon 

before the mountain rain turned to snow. Up to 4 feet of snow fell at Frazier Park; the strong winds created drifts as high as 6 

feet deep. Snow caused the closure of Interstate 5 over the Grapevine, and snow even fell on the Temblors and Diablo Range 

along the west side of the San Joaquin Valley. In Yosemite National Park and the surrounding area, winds toppled trees and 

downed power lines, and the combination of heavy snow and rock slides closed roads into the Park. This was the first time 

since the floods of January, 1997, that Yosemite National Park was closed due to weather. Heavy snow and downed oak trees 

also plagued the El Portal and Wawona areas. Due to the power outages, Yosemite park officials evacuated some visitors to the 

park for a period of time due to the extensive impacts from this storm. 

The morning of March 21st saw hail falling on the San Joaquin Valley floor, including near Rio Bravo and later over the Fresno 

-Clovis metro area. By the afternoon, hail was reported in Selma and Visalia, with Â½-inch hail reported in the latter city. In 

the Tehachapi Mountains, up to a foot of new snow was reported. 

The trough moved into the Great Basin, but a trailing short-wave brought light showers to the Kern County mountains and the 

far south end of the San Joaquin Valley during the early morning hours of March 22nd. Isolated showers were reported over 

parts of downtown Bakersfield, but stayed just south of Meadows Field.

Yet another storm reached the central California interior on March 23rd-24th. A line of thunderstorms developed on the 23rd 

over Merced County, then moved eastward into Madera and Mariposa Counties. Thunderstorms at the south end of the line 

propagated southward into Fresno County, ultimately reaching parts of Fresno and near Hanford. In fact, Fresno reported over a 

half inch of rain that day, with 0.38 inch falling in an hour at Fresno-Yosemite International Airport during the afternoon. Small 

hail, frequent lightning, and brief heavy rainfall were the main impacts of these storm cells. Funnel clouds were reported west 

of Madera, and near Clovis and Kerman; none touched down. The heavy rains caused flooding in the Southern Sierra Nevada 

foothills east of Fresno, as well as in downtown Fresno and southeast of Bakersfield. Convective cooling lowered the snow 

level down to 2200 feet in Mariposa and Madera Counties. 

The last major storm of the month arrived on March 24th. This storm brought gusts to 45 mph to the west side of the San 

Joaquin Valley, and gusts to 65 mph in the Kern County mountains and deserts. Convective activity was limited to near 

Merced, with several reports of road flooding due to the already saturated ground. Thunderstorms and showers moved east into 

the foothills of Madera and Mariposa Counties, where the heavy rains triggered rock and mud slides. Mainly light showers 

occurred southward. The trough moved east of the region on the 25th, with residual light showers in its wake. Additional light 

snow fell in the Southern Sierra Nevada measuring around 5 inches or less. Local media reported that the roof of a vacant store 

at Shaver Lake collapsed on March 26th due to 6 feet of snow accumulation on the roof.

During the frequently stormy period that began on the 18th and ended on the 28th, as much as 7 inches of rain fell in the San 

Joaquin Valley and up to 10 inches of rain drenched the adjacent foothills while the higher elevations of the Sierra (above 7000 

feet) received snow accumulations of up to 15 feet. Excessive runoff, combined with an increase in reservoir releases at the 

major dams caused higher than normal flows along rivers and streams through the end of the month. The Merced River at 

Stevinson peaked a half of a foot below flood stage at 4:30 pm on the 21st but otherwise remained well above monitor stage 

during the last two weeks of the month. Water levels along the San Joaquin River approached levels that had not been observed 

since January, 1997. At Newman, the river first rose above monitor stage on the morning of the 23rd and remained above 

monitor stage for the remainder of the month. Water flowed into the Fishermanâs Bend trailer park along the San Joaquin River 

near Newman by the 28th where voluntary evacuations were conducted. In Merced County, several water swollen creeks 

briefly flowed out of their banks on the morning of the 20th and caused minor flooding. 

The last major storm of the month arrived on March 24th. This storm brought gusts to 45 mph to the west side of the San 

Joaquin Valley, and gusts to 65 mph in the Kern County mountains and deserts. Convective activity was limited to near 

Merced, with several reports of road flooding due to the already saturated ground. Thunderstorms and showers moved east into 

the foothills of Madera and Mariposa Counties, where the heavy rains triggered rock and mud slides. Mainly light showers 

occurred southward. The trough moved east of the region on the 25th, with residual light showers in its wake. Additional light 

snow fell in the Southern Sierra Nevada measuring around 5 inches or less. Local media reported that the roof of a vacant store 

at Shaver Lake collapsed on March 26th due to 6 feet of snow accumulation on the roof. 

A weak frontal system reached the area on the 26th-27th, bringing cooler temperatures but only light precipitation and a few 

gusty winds. This storm moved east of the central California interior on the 28th, with an upper-level ridge building into the 

state behind it to bring a strong warming trend. 

High temperatures in the central and southern San Joaquin Valley warmed into the lower 80s on the last day of the month. This 

was the first day of 2011 that either Bakersfield or Fresno reached 80 degrees, with highs of 82 and 81 degrees, respectively. 

The last day Fresno had reached 80 degrees was November 5th, 2010, when Fresno had a high of 90 degrees. Bakersfield last 

saw an 80-degree day on November 6th, 2010, with a high of 85 degrees.

A magnitude 9.1 earthquake struck Japan on March 10th, sending a tsunami toward the west coast of the U.S. The tsunami 

arrived in Southern California in the form of a series of tidal surges, the first observed around 9 am March 11th. The main 

damage was one bait barge in Mission Bay that broke loosed by the strong currents and superficial damage to a few nearby 

boats as a result. Surge amplitudes of 2 feet at San Diego and 1.7 feet at La Jolla were measured, as well as a maximum 

difference in water level near 4 feet at San Diego (surge and retreat). The peak surge at San Diego was at 1 am March 12 when 

a barge was reported to break loose again in Mission Bay. The beaches did have a tsunami warning posted and a lot of people 

gathered to observed despite the lifeguards warning. Media coverage was extensive with live helicopter footage during the 

morning of the 11th, and frequent break-ins for live beach coverage from Orange to San Diego Counties.

The month of March 2011 was the eighth least snowiest March on record with 2.9 inches of snowfall at Denver International 

Airport. The seasonal snowfall of 20.6 inches, measured between July 1, 2010 and March 31, 2011 made it the third least 

snowiest season to date. The combination of above normal temperatures, windy conditions and sparse precipitation resulted in 

very dry conditions along the Front Range Foothills, Urban Corridor and Northeast Plains. Over two dozen wildfires occurred 

throughout the region in March alone. Although structural damage was limited, the wildfires threatened hundreds of homes 

and forced the evacuation of thousands of residents and numerous road closures. 

The first significant wildfire occurred in Left Hand Canyon, in the foothills west of Boulder, from March 11-13th. Gusty winds 

in the area allowed the fire to consume a total of 622 acres. The Indian Gulch Wildfire occurred just west of Golden, between 

Clear Creek and Golden Gate Canyons from March 20-25th. Strong winds coupled with very rugged terrain hampered fire 

fighting efforts and allowed the wildfire to consume another 1570 acres. A third large wildfire near Franktown, quickly 

consumed 1600 acres of primarily pastureland on March 24th but threatened hundreds of nearby homes.

CONNECTICUT, Northwest 

A cold front moved gradually southeastward across the region during the day Monday, March 7th, as a wave of low pressure 

moved northeastward along the boundary. To the south of the boundary, it was mild as the area was in the warm sector of the 

low pressure system. The storm tapped into both Atlantic and Gulf moisture, resulting in heavy rainfall of 3 to 4 inches across 

Litchfield County Sunday, March 6th, into Monday, March 7th. The heavy rainfall, combined with runoff from snowmelt due 

to the mild temperatures, resulted in widespread flooding of rivers, streams, creeks, roads, and basements. Evacuations 

occurred in some communities as flood waters cut residences off from main roads.

the Delaware Bay also produced minor tidal flooding along the Delaware River and tidal sections of its tributaries during the 

early morning high tide cycle on the 11th. It also slowed the runoff of inland waterways. The high tide at Reedy Island (New 

Castle County) reached 7.7 feet above mean lower low water. Minor tidal flooding starts at 7.2 feet above mean lower low 

water. 

The strong winds were caused by the pressure difference between a strong high pressure system over the Canadian Maritimes 

and an approaching frontal boundary from the Ohio Valley. This difference was at its strongest during the late afternoon and 

evening of the 10th and lessened after a warm front moved through Delaware.

DELAWARE 

Sharpless Road and Ashland Clinton School Road were flooded by the Red Clay Creek near Yorklyn and Hockessin. Farther 

downstream, the Red Clay Creek at Wooddale was above its 7 foot flood stage from 742 p.m. EST through 1109 p.m. EST on 

the 10th. It crested at 7.32 feet at 915 p.m. EST. Farther downstream, the Red Clay Creek at Stanton was above its 15 foot flood 

stage from 830 p.m. EST through 1152 p.m. EST on the 10th. It crested at 15.29 feet at 945 p.m. EST. The Brandywine Creek 

at Wilmington was above its 16.5 foot flood stage from 718 a.m. EST through 405 p.m. EST on the 11th. It crested at 17.34 feet 

at 1115 a.m. EST. 

Event precipitation totals within New Castle County included 2.24 inches in Mill Creek, 1.83 inches in Newport, 1.46 inches at 

the New Castle County Airport and 1.29 inches in Newark. 

Heavy rain caused poor drainage and creek flooding in New Castle County. While event precipitation totals averaged 1.5 to 2.0 

inches within the county, event precipitation totals reached between 2 and 3.5 inches in the headwater regions of some of the 

creeks in Chester County, Pennsylvania. Rain started in the late evening of the 9th, fell heavy at times during the daylight hours 

on the 10th and ended during the early morning on the 11th. The heavy rain was caused by a low pressure system that moved 

from the Southern Plains on the morning of the 8th northeast into Iowa on the morning of the 9th, Michigan on the morning of 

the 10th and into the eastern Great Lakes on the morning of the 11th. This system was able to tap moisture from both the Gulf 

of Mexico and Atlantic Ocean and lift it over its frontal boundaries. The rain ended once the low's cold front moved through 

Delaware.

A fast easterly moving low pressure system that moved off the southern North Carolina coast early that day brought a light 

accumulating snow to southern parts of Sussex County on the morning of the 27th. Snow began after Midnight EDT on the 

27th and was over by 9 am EDT. Snowfall included 2.5 inches in Delmar, 2.0 inches in Laurel, 0.5 inches in Selbyville and 0.3 

inches in Georgetown. Because the snow fell early on a Sunday morning (the 27th) and less accumulated on roadways, no 

serious accidents were reported.

A strong pressure gradient between high pressure over the Atlantic Ocean and a cold front moving in from the Ohio Valley 

resulted in gusty southeast winds over the Tidal Potomac River and Chesapeake Bay. The strong onshore flow caused water 

levels to be elevated which led to coastal flooding along areas near the Tidal Potomac River. 

12 1033EST 


Heavy rainfall on March 10th caused elevated fresh water levels upstream along the Potomac River. A rush of freshwater from 

the Potomac River caused water levels to rise along the Tidal Potomac River in Washington DC on the 12th. The elevated 

water levels resulted in moderate coastal flooding near Wisconsin Avenue.

The ASOS Station at the Sarasota-Bradenton International Airport measured a wind gust of 60 mph or 52 knots. 

A stalled frontal boundary was in place across central Florida. As the boundary began to lift north drawing in abundant warm 

moist air over the area, an upper level disturbance moved over the area and a squall line developed and quickly moved across 

the northern half of the area. Several areas of damaging winds and a tornado resulted from this fast moving line on March 30th. 

The warm front continued to lift north over northern Florida as a developing low pressure system shifted into the northeastern 

Gulf of Mexico. As this system moved across northern Florida, the cold front pushed into the local area and another series of 

squall lines moved across the area through the day on March 31st. Several tornadoes and areas of damaging winds occurred 

across the greater Tampa Bay area. Note: The measured wind gust of 52 knots is equivalent to 60 mph.

A broad and highly diffluent upper trough was moving slowly through the south central U.S. into the eastern U.S. A pattern 

that became all too familiar across the U.S. during the later half of March and much of April. As the trough moved into the 

eastern U.S. during the 10th and 11th, it deepened significantly and took on a strong negative title across the eastern U.S. This 

system was associated with widespread severe weather and flooding across the Arklatex region, the lower Mississippi Valley, 

and the western Tennessee Valley region. As the system spread into Georgia, it also produced flooding, flash flooding, and 

severe weather. Widespread rain and thunderstorms spread across northwest Georgia late on the 8th and continued into the 

early morning hours of the 9th. This precipitation was culminated by a near solid north-south oriented squall line or quasilinear 

convective system (QLCS) that tracked across north and central Georgia. The QLCS entered west Georgia around 9 am 

and tracked into east Georgia during the early afternoon. Moderate to heavy rain continued behind this QLCS into the 

afternoon across northwest Georgia, finally ending by evening. Rainfall of four to five inches was common across northwest 

Georgia from LaFayette, to Calhoun, to Cedartown, and Buchanan. Several flash flood and flood events were observed in this 

part of the state. 

As the squall line or QLCS moved into central and east Georgia it began to form bowing segments and line-echo-wave patterns 

(LEWPs) resulting in several damaging wind events across this part of the state. Fortunately, no tornadoes were observed with 

this event. Note: The estimated wind gust of 50 knots is equivalent to 58 mph.

The Madison County 911 Center reported that a tin roof was blown off a church on Shirley Road just south of the Franklin 

county line and the city of Royston. Some two-by-fours were also torn off the same building. Three trees were down on 

Shirley Road and Doug Drake Road. One large pine tree fell on a home causing damage to its roof. A couple of telephone 

lines were down along Shirley Road as well. 

A backdoor cold front was edging southwestward through South Carolina and into northeast Georgia. An upper trough was 

moving through the mid-Atlantic and northeastern United States, while a large upper ridge was developing in the central United 

States. The combination of unseasonably warm temperatures in the 80s, the backdoor front, and the northeast U.S. upper 

trough, provided support for a mesoscale convective complex of thunderstorms across upstate South Carolina. The tail end of 

these storms skirted across extreme northeast Georgia, affecting mainly Madison county. Note: The estimated wind gust of 50 


23 2212EST 


A damage survey conducted by the National Weather Service Forecast Office in Peachtree City, Georgia and the Pickens 

County Emergency Management Director confirmed that extensive damage to trees and property across the northern half of 

Pickens county was the result of a 75 mph straight-line thunderstorm winds. Two large chicken houses, just south-southwest 

of Talking Rock, collapsed and were destroyed. Eight homes in the same general area suffered minor damage from downed 

trees and/or tree limbs. In Jasper, the roof of a large building was removed by the strong winds. It should be noted, however, 

that this roof was built on top of an existing roof. Several power lines were also down in the area between Talking Rock and 

Jasper. 

A vigorous upper-level trough was moving through the Ohio Valley region toward the mid-Atlantic. A cold front accompanied 

the upper trough and was moving southeast into the region. A mesoscale convective complex (MCS) developed across the 

Tennessee Valley and moved southeast into north Georgia during the evening hours. Although the system was generally 

dissipating as it moved further south away from the better upper-level support and dynamics, it maintained considerable 

intensity as it moved into north Georgia. The leading edge of the MCS developed into a bowing west-east oriented line 

segment. As a portion of this segment bowed out across Pickens county, it produced 75 mph winds which caused considerable 

damage to property and trees. Damaging winds were also reported across Dawson and Lumpkin county before the storms 

dissipated. Note: The estimated wind gust of 65 knots is equivalent to 75 mph.

The public observed quarter-sized hail near Rome. 

A quasi-stationary frontal boundary extended from north Texas to north Georgia early on the 26th. The front took two to three 

days to move from north Georgia southward to the Gulf Coast. The upper flow was highly zonal, but embedded with numerous 

vigorous short waves. An unseasonably warm, unstable air mass presided south of the frontal boundary. Numerous areas and 

complexes of thunderstorms developed in waves repeatedly along the front boundary and plagued north and central Georgia for 

two to three days. Many counties across the area were impacted by golf ball and larger hail. There was one report of hail over 

four inches in diameter in west central Georgia near Newnan. While hail was the predominate severe weather type with this 

outbreak, there were several reports of damaging winds and even one tornado in central Georgia. In addition, there were 

several lightning incidents as many of the storms produced intense cloud-to-ground lightning.

2 W Fairplay 

3 E Hannah 

A vigorous upper-level trough was moving through the Ohio Valley region toward the mid-Atlantic. A cold front accompanied 

the upper trough and was moving southeast into the region. A mesoscale convective complex (MCS) developed across the 

Tennessee Valley and moved southeast into north Georgia during the evening hours. Although the system was generally 

dissipating as it moved further south away from the better upper-level support and dynamics, it maintained considerable 

intensity as it moved into north Georgia. The leading edge of the MCS developed into a bowing west-east oriented line 

segment. As a portion of this segment bowed out across Pickens county, it produced 75 mph winds which caused considerable 

damage to property and trees. Damaging winds were also reported across Dawson and Lumpkin county before the storms 

dissipated. Note: The estimated wind gust of 52 knots is equivalent to 60 mph.

A storm spotter observed penny-sized hail near Ringgold. 

A short wave was moving into the southeast U.S. and helping to carve out a full-latitude negatively tilted eastern U.S. trough. 

This trough swept through the eastern U.S. between March 31st and April 2nd. Widespread showers and thunderstorms 

accompanied this system across north and central Georgia. However, because of several days of previous convective activity, 

the atmosphere was relatively stable in comparison to the March 26th - March 28th period. Although some of the 

thunderstorms became strong and many produced heavy rain, none of the thunderstorms reached severe limits. Early during 

the event, a storm approached severe limits in northwest Georgia near Ringgold and produced penny-sized hail.

Although heavy rain began to taper off during the late morning, high water conditions persisted along the Soque River near 

Clarkesville through the afternoon. 

Widespread heavy rain developed ahead of an area of low pressure, with 3 to 5 inches of rain falling over much of the 

mountains of northeast Georgia. This resulted in an isolated instance of flash flooding. 




For the second time in three days, heavy rain resulted in flash flooding along the Soque River near Clarkesville. Roads, trails 

and some buildings in Pitts Park were flooded when the river left its banks. 

An area of low pressure brought widespread rain to the region. Orographic effects concentrated the heaviest rain over the 

southern mountains of North Carolina and the mountains of northeast Georgia. This caused flooding in the same areas that saw 

flooding three days before.

Minor flooding was observed along Bridge Street in Moscow as water overflowed its banks along Paradise Creek. The City of 

Moscow utilized sandbags and temporary gravel walls to contain the flood waters. 

A parade of storm systems moved along a deep surge of subtropical moisture aimed into the Northern Idaho Panhandle March 

10th through the 11th. This resulted in periods of moderate to heavy rainfall and mild, breezy conditions. The combination of 

heavy rain and melting snow resulted in sharp rises of Paradise Creek in the Idaho Palouse with minor flooding observed in the 

city of Moscow. Upstream sensors of the Paradise Creek Basin reported over an inch of rainfall over the two day period.

A stationary trough of low pressure off the Pacific Northwest Coast steered a deep fetch of subtropical moisture into the Idaho 

Panhandle which persisted from March 29th through early April. This resulted in several rounds of moderate to heavy 

precipitation, which primarily fell as rain below 6000 feet. Mild temperatures and breezy winds accompanying the subtropical 

moisture feed resulted in excessive mid-elevation snowmelt. The combination of heavy rainfall and excessive snow melt 

resulted in sharp rises in most basins within the Central Idaho Panhandle and Idaho Palouse. In addition, saturated soils 

became unstable in some locations resulting in debris flows.

Flooding of the Ohio River continued from late February through the entire month of March. The exceptions were at Golconda 

and Shawneetown, which fell below flood stage between the 28th and 30th. The flooding was considered moderate. The 

flooding was due to a prolonged active weather pattern that carried over from February. From February 23 through March 14, a 

total of 8.31 inches fell at Evansville, IN and 9.43 inches at Paducah, KY. Isolated evacuations of some lowland residents were 

conducted. In the city of Metropolis in Massac County, several streets were closed, a few residences were evacuated, and a 

casino riverboat was closed for several days. The closure of the casino had a major impact on the local economy. Flooding of 

the casino's parking lot and entrance prompted the closure. There was very little property damage to the casino itself. In 

Gallatin County, the community of Old Shawneetown was threatened, but the river fell short of entering houses. Several mobile 

homes and trailers in Hardin County were pulled away from the water. Rosiclare City Park was flooded, damaging playground 

equipment and rest rooms. Rural Pope County roads were flooded in many low areas, including around Golconda, Brownfield, 

and Hamletsburg. Water was very near some homes in the Hall Town area of Pope County. The Golconda marina was closed. 

In Pulaski County, a road was closed at the Cache River (a tributary of the Ohio). Several Alexander County roads were closed. 

There was considerable flooding of low-lying fields and woodlands near the river. Riverside parks and recreation areas were 

flooded, including portions of Fort Massac State Park near Metropolis. Some secondary roads near the river were flooded. The 

river crest at Cairo was 53.41 feet, which was within six inches of the January, 2005 flood and almost three feet lower than the 

1997 flood. At Shawneetown, the crest was about three feet lower than the 2005 flood and several feet lower than 1997.

Based on a National Weather Service damage survey, it appeared the wind damage in Noblesville during the evening of 

Wednesday March 23 was caused by downbursting straight line winds. The majority of the damage was uprooted pine trees 

and downed Bradford Pear trees and limbs, both of which tend to be damaged by winds of 60 to 80 mph. The trees were laid 

down in an outward fanning or diverging pattern often found with a downburst wind event. Most trees west of State Road 37 

were blown down by a strong south wind. Trees and fences east of State Road 37 were blown down by strong west-southwest 

winds. This damage occurred at the lead edge of the storm, not the usual location at the rear of the storm where a tornado 

typically would form. Other damage included stripped shingles and siding from around a dozen homes.

Scattered thunderstorms formed along a boundary that sliced from eastern to southern portions of Indiana during the early 

afternoon hours on the 23rd. By the late afternoon and early evening, an elevated front dropped south into central Indiana 

which allowed for an increase in moisture across the northern half of the warning area. Scattered thunderstorms developed 

along this boundary and produced large hail and some damaging wind across northern portions of the Indianapolis metro area.

Flooding along the Mississinewa River continued into the first day of March. High water from the river spilled over into eastern 

portions of Marion as well as into the Stonecrest Mobile Home Community, where residents woke to flooded residences and 

roads. Sufficient water covered the entrances to the community to stop residents from entering and exiting the area, as well as 

causing school buses to divert away from the area. While no exact damage figures were provided, damage likely exceeded 1 

million dollars from a combination of structural and roadway damage. 

Heavy rains that occurred February 27th and 28th continued to cause flooding problems, mainly on local rivers, creeks and 

streams. While most concerns were related to agricultural lands, residents in Grant county continued to see flooding concerns 

beyond these areas.

Flooding of the Ohio River occurred for most of the month of March. The flooding was considered minor to moderate. The 

flooding was due to a prolonged active weather pattern that carried over from February. From February 23 through March 14, a 

total of 8.31 inches fell at Evansville, IN. Isolated evacuations of homes in low-lying areas were conducted. Numerous 

roadways were closed. Most of the closed roads across the region were rural county or farm roads. In Vanderburgh County, 

most of the flooded roads were south of Interstate 164 in the southeast part of the county and in lowland areas in the southwest 

part of the county. There was considerable flooding of low-lying fields and woodlands near the river. Backwater flooding of 

Pigeon Creek in the Evansville area resulted in a water rescue. Three men were inside a small boat when it began to sink. The 

men were forced to hang onto trees to stay above the water. The men were rescued within minutes. Riverside parks and 

recreation areas were flooded. Very few residences were flooded. The crest at the Evansville river gage was 44.20 feet, which 

was nearly identical to the January, 2005 flood and over three feet lower than the 1997 flood.

A considerable amount of snow had accumulated during the previous winter across northern Iowa and southern Minnesota. As 

the snow melted, river levels rose across northern Iowa with numerous sites reaching minor to moderate flood levels. A couple 

of the sites, most notably Estherville and Cedar Falls, briefly reached low end major levels. It was fortunate that the snow 

melted relatively slowly and also the fact that no significant rainfall occurred during the melt. Rainfall that occurred later in the 

month was held in check by sub-freezing temperatures. The fact that reduced the flooding was a cold spell that moved into the 

state after the 22nd. Temperatures were highly variable during the month as is typical for this time of year as the weather 

transitions from winter to spring. A very mild period prevailed from the 14th through the 22nd but was followed by nine 

consecutive colder than normal days to finish out the month. Sibley recorded the Marchâs lowest temperature with a low of - 

5° on the 2nd while Shenandoah and Sidney tied for the highest temperatures with 81° readings on the 22nd. Temperatures 

for the month as a whole averaged slightly below normal over the northwest and a little above normal over the southeast. 

Precipitation was fairly evenly distributed throughout the month and was generally greater than normal over the northeast onethird 

of Iowa and well below normal over the western third of the state. About half of the monthâs precipitation came in two 

storms. The first storm, on the 8th-9th, started with rain statewide but transitioned to snow over the northwestern two-thirds of 

Iowa. Greatest snow amounts of three to five inches fell over north central and northeast Iowa while rain totals locally 

exceeded an inch over the southeast. The second event on the 22nd-23rd brought thunderstorms and rainfall statewide with 

rain amounts up to two inches over parts of north central Iowa. Damage from the river flooding was limited to agricultural 

areas for the most part. Considerable advance preparation in more flood prone areas also helped to reduce losses.

A trained spotter in Cedar Falls reported nickel size hail. 

A strong warm advection pattern set up over the state during the early morning hours of the 20th. A low level jet of 50 to 70 

MPH transported moisture into the state. Thunderstorms erupted with limited CAPE in the 500 J/kg range. The storms were 

initially severe southwest of Iowa and weakened as they moved away from their support. Thunderstorms in Iowa produced 

brief heavy rainfall and pea size hail in several locations. One report of nickel size hail was received from the Cedar Falls area 

of Black Hawk County.

March 2011 

IOWA, Central 

Low pressure formed to the west of Iowa and during the morning it was located over central Nebraska with a warm front 

extending east-southeast across southern Iowa. The low advanced east during the day as the warm front moved little. Initially, 

the airmass was capped by a strong elevated mixed layer. During the late afternoon and early evening hours, a strong upper 

level short wave moved into the area. Temperatures aloft fell rapidly, destabilizing the atmosphere. Meanwhile, a strong low 

level jet formed ahead of the approaching low with winds of 40 to 50 kts. This helped to bring in moisture and increased the 

precipitable water values to around an inch over much of Iowa. By late afternoon, most unstable CAPE values were in the 

1000 to 2000 J/kg range. Surface lifted indices were not all that impressive, however the elevated values were in the -3 to -6 C 

range. The atmosphere was strongly sheared with 50 to 70 kts of available shear. The LCL values were quite low as strong 

heating had not taken place during the day. LCL heights were between 500 and 1000 meters. Downdraft CAPE was quite high 

with values just ahead of the convection between 700 and 1000 J/kg. The freezing level was quite low, near 11,000 feet, and 

available CAPE in the -10 to -30 C layer of the atmosphere was between 400 and 500 J/kg. Thunderstorms fired along and just 

south of the surface low along a dry line ahead of the associated cold front. Convection was strong and moved rapidly 

northeast. There were two areas of thunderstorms. A line of strong to severe thunderstorms formed just ahead of the cold 

front, with more isolated severe convection forming ahead of the main line. There were numerous reports of tornadoes, mainly 

with the leading convection. The three strongest tornadoes took place west to northwest of Creston in Union County, and 

northwest to north of Winterset in Madison County and southeast of Massena in Cass County. The tornado in Cass County 

touched down approximately 1/2 mile east of the intersection of Iowa Hwy 148 and County Hwy G61. It damaged the canopy 

to an outdoor storage building and tipped over some industrial machinery. It continued northeast and damaged a structure...and 

caused some minor additional damage to a farmstead north of the intersection of County Hwy G61 and 760th St. Finally, it 

damaged some outdoor storage bins south of the intersection of County Hwy G53 and 770th Street. It then lifted. The same 

parent storm continued northeast and a small EF0 tornado touched down briefly near Bridgewater in Adair County. In Madison 

County, A tornado touched down 10 miles northwest of Winterset. The tornado was characterized by a large circulation up to 

0.8 tenths of a mile wide (Iowa Helicopter) and generally of EF1 (90-100 MPH wind) strength. Eyewitnesses report the 

tornado was rain wrapped and difficult to distinguish from the rain shield as it approached them from the southwest. The 

tornado moved across several residences, many of which had broken windows and some roof damage along with significant 

tree and outbuilding damage. One newly constructed house that was near completion, slid off its foundation with the metal tie 

down straps either sheered off or pulled out of the concrete foundation. This damage is consistent with winds around 120 MPH 

which are EF2 strength. The roof structure remained intact and was aided by hurricane clips. Several other residences suffered 

partial roof removal with no hurricane clips noted. One other location had numerous trees either uprooted or topped and several 

outbuildings with the roofs blown off. Objects near the ground did not suffer near as much damage suggesting the peak winds 

at this location were just off the surface. The tornado lifted around 10 miles north northeast of Winterset or 5 miles south of 

Van Meter around 1735 CST. The tornado in Union County was not as intense, with damage there relatively minor. In addition 

to the line of severe thunderstorms, there was also convection that developed to the north of the low pressure track. Outside of 

the tornadic storms, the primary mode of severe weather was hail. There were reports of hail with most of the storms as they 

passed, with several reports of hail from quarter up to golf ball in size. Hail caused damage to roofs and vehicles. Fortunately, 

the crops had not been planted so there wasn't any agricultural loss. A few reports of strong winds were received with wind 

gusts in the 60 to 65 MPH range. Some tree and power line damage occurred, but it was not widespread. Heavy rainfall caused 

minor flooding in the metropolitan Des Moines area. A rainfall of 1.73 inches in under 2 hours in West Des Moines resulted in 

minor urban flooding along EP True Parkway. Water was standing 1 to 2 feet deep in low drainage areas along the parkway. 

There were also numerous reports of urban flooding around the city with water standing in intersections. As the thunderstorms 

moved through Butler County, lightning struck a barn near Shell Rock. The lightning caused damage to the barn and a minor 

fire. Note: The estimated wind gust of 52 knots is equivalent to 60 mph.

A trained spotter 6 miles northeast of Van Horne reported pea to penny size hail for 5 minutes. 

Thunderstorms developed early in the morning on March 20, 2011 across portions of northeast Iowa and northwest Illinois, and 

then again during the early afternoon. The nose of low level moist advection, combined with a series of weak short waves, 

helped trigger the elevated storms. In addition, steep mid level lapse rates and a modest dry layer proved successful in 

producing pea to quarter size hail at several locations. A trained spotter about 2 miles southeast of Florence, Illinois reported 

nickel to quarter size hail right on the Stephenson/Ogle county line.

March 2011 


A storm chaser caught a rope tornado on video southwest of Defiance. The narrow and weak tornado apparently caused no 

damage as it remained in an open field and was from the same supercell that spawned a larger tornado to the southwest in 

Harrison county a little earlier. 

A strong upper level trough and associated cold front pushed across the region during the afternoon and evening of March 22. 

The upper level system caused low pressure to deepen over eastern Nebraska/northeast Kansas with a warm front extending 

northeast from the low into east central Nebraska and southwest Iowa. By mid afternoon, ahead of the cold front and south of 

the warm front, temperatures climbed into the upper 70s to lower 80s and dew point temperatures reached the upper 50s. The 

instability and shear near the low and warm front created a favorable environment for supercell development, a few of which 

produced damaging hail and at least 3 tornadoes in the area.

This Tuesday afternoon featured the first strong to severe thunderstorms of 2011 across portions of North Central Kansas, with 

quarter to ping pong ball size hail reported in the Tipton and Beloit areas. The storms initially started out as an area of weaker 

showers across Northwest Kansas during the early afternoon, generally tied to an area of low to mid level frontogenesis behind 

a surface cold front well off to the east. As the showers drifted east into North Central Kansas, they gradually strengthened into 

a few thunderstorms. One of these eventually became severe, taking advantage of modest elevated instability between 500- 

1000 J/kg and very strong deep-layer wind shear of at least 60 knots. This storm first entered Rooks County around 4 PM with 

small hail around dime size reported near Palco. The hail size then increased as the storm made its way into Mitchell County.

Another major rain event occurred from late on the 9th into the evening hours of the 10th. Rain amounts of 1 to 2 inches were 

common. Including this episode, the accummulative affects of 5 significant rain events across the upper Ohio River Valley 

since Febraury 21st, caused the Ohio River to flood. Along many reaches, it was the highest stage on the Ohio River since 

2005. The crest was 2 to 3 feet above the assigned flood stages. This crest occurred late on the 12th through the morning hours 

of Sunday the 13th. 

Many of the flood prone parks and recreational areas along the river were flooded including some of their outbuildings. 

Several roads were closed, causing motorists to take alternate routes for a few days.

Flooding of the Ohio River occurred for most of the month of March. The flooding was considered moderate. The flooding was 

due to a prolonged active weather pattern that carried over from February. From February 23 through March 14, a total of 8.31 

inches fell at Evansville, IN and 9.43 inches at Paducah, KY. Isolated evacuations of some lowland residents were conducted. 

In Crittenden County, the community of Tolu was threatened. In Livingston County, homes were threatened in Birdsville, and a 

few homes were surrounded by water in Ledbetter. Just west of Paducah, a 90-year-old man drowned (direct fatality) after he 

drove around barricades down a flooded secondary road. The victim could not see the edge of the road and ended up 

submerged in 12 feet of water in a ditch. Several people who tried to rescue the victim were taken to a local hospital for 

treatment of hypothermia. In western McCracken County, several homes were threatened, and they were protected with 

sandbags. All along the Ohio River, a number of roadways were closed. Most of the closed roads across the region were rural 

county and state roads. There was considerable flooding of low-lying fields and woodlands near the river. Riverside parks and 

recreation areas were flooded. Very few residences were flooded. The crest at the Paducah river gage was 47.81 feet, which 

was nearly identical to the January, 2005 flood and almost four feet lower than the 1997 flood.

An area of low pressure over southeast Louisiana moved east along a warm front into southeast Mississippi through the period. 

This was followed by the passage of a strong cold front. This storm system triggered severe storms with scattered reports of 

hail and wind damage over central Mississippi and northeast Louisiana during the late afternoon and overnight hours. Hen size 

and tennis ball size hail was reported with a few of the storms. Heavy rainfall led to flash flooding along the Interstate 20 

corridor as well.

The month of March, 2011 remained on the dry side across most of the region. While the month did see some appreciable 

rainfall, it was not enough to stifle the ongoing drought conditions across the northern half of the state. At the end of the month, 

nearly the entire region was under D3 Extreme Drought conditions. The only exception to this was extreme Northeast 

Louisiana near Monroe which was under D2 Severe Drought conditions. The following are a few selected cities across

Low pressure tracking along a stalled frontal boundary across Downeast Maine brought abundant moisture to the region. 

Across northern portions of the region rain transitioned to snow during the evening of the 6th with colder air in the wake of the 

front. Across central portions of the region...just north of the stalled front...low levels cooled while the low drew warmer air 

aloft over the frontal boundary. This resulted in snow and sleet transitioning to freezing rain. Snow north...with mostly freezing 

rain across central portions of the region...then continued through the afternoon of the 7th. Storm total snow accumulations of 

15 to 20 inches were common across northern portions of Aroostook...Piscataquis and Somerset counties...with totals of around 

24 inches across extreme northwest areas. Storm total snow accumulations in a zone from southeast Aroostook county...across 

northern Penobscot county...to central and southern Piscataquis county varied significantly. Snow accumulations across 

northern portions of this zone generally ranged from 8 to 14 inches...with 2 to 6 inches across the remainder of the region where 

a greater portion of the precipitation fell in the form of sleet and freezing rain. Ice accumulations of 1/4 to 3/4 of an inch were 

common...with localized totals of around 1 inch. South of the frontal boundary...across Downeast Maine...enough warm air was 

drawn into the storm to allow most of the precipitation to fall in the form of rain. 

The combination of heavy wet snow and significant ice accumulation snapped branches...toppled and weighed down many 

trees. The falling trees and branches...along with ice build up on wires...brought down numerous power lines contributing to 

power outages. The most numerous power outages occurred in a zone from southern Piscataquis county....across central and 

northern Penobscot county...to southeast Aroostook county. Thousands of customers lost power for varying amounts of time in 

this zone...some without power for over 24 hours. Fallen trees and power lines also blocked roads in some areas.

MAINE, South 

On Saturday morning, March 5th, a frontal system was located over the Ohio and Mississippi River Valleys. Ahead of the 

front, south to southwest winds ushered in some very mild air. Temperatures across most of southern and central Maine 

warmed into the lower 50s during the day and remained well above freezing Saturday night. By Sunday morning, March 6th, 

the front had moved east to the Appalachians and the strong southerly flow ahead of the system continued to bring mild 

temperatures and tropical moisture northeast from the Gulf of Mexico and southern Atlantic Ocean. Temperatures Sunday 

climbed into the upper 40s to middle 50s across the southern part of the state. An area of low pressure began to develop over 

the southeastern states Sunday and then moved northeast along the frontal boundary Sunday night and Monday as it intensified 

rapidly. Light rain, associated with the approaching cold front began to fall Sunday morning. The precipitation became heavy 

by late afternoon as the intensifying area of low pressure approached Maine from the south. At the same time, colder air started 

funneling into the state from the north and changed the rain to snow across the Western Mountains during the afternoon. 

Across the state, heavy snow, freezing rain and rain continued through the night and finally ended Monday afternoon, March 

7th. In addition to the precipitation, strong and gusty winds developed across the region Sunday night and continued Monday. 

Across Western Mountains, snowfall accumulations from the storm ranged from 13 to 23 inches. 

Rainfall amounts across the southern part of the state were generally in the 1 to 3 inch range, with locally higher amounts. In 

addition, melting snow, due to the mild temperatures, contributed to the runoff from the storm. The rainfall and melting snow 

caused river levels to rise which caused river ice to break and move downstream.

A strong cold front slowly passed through the area on the 10th. Plenty of moisture from the Gulf of Mexico and Atlantic Ocean 

were drawn into the region ahead of the front. A warm and moist southerly flow ahead of the front caused limited instability to

The Susquehanna River at the Conowingo Dam had moderate flooding, mainly on the 12th. The river was above its 23.5 foot 

flood stage from 950 a.m. EST through 101 p.m. EST on the 11th. It crested at 24.15 feet at 1030 a.m. EST. The river was 

again above its 23.5 foot flood stage from 331 p.m. EST on the 11th through 230 a.m. EDT on the 14th. It crested at 27.79 feet 

at 1045 a.m. EST on the 12th. This was the highest flow rate at the Conowingo Dam since the precipitation associated with 

Hurricane Ivan in September of 2004. 

Event precipitation totals within Cecil County included 2.33 inches in Fair Hill, 1.73 inches in Cherry Hill and 1.43 inches in 

Elkton. 

Rain as well as melting snow in the upper Susquehanna Basin caused moderate flooding along the Susquehanna River in Cecil 

County. Locally event precipitation totals averaged around 2.0 inches. Locally rain started in the late evening of the 9th, fell 

heavy at times during the daylight hours on the 10th and ended during the early morning on the 11th. The flooding along the 

Susquehanna criss-crossed the start of Eastern Daylight Time on the 13th. 

The southeast wind up Chesapeake Bay also produced minor tidal flooding during the evening high tide cycle on the 10th. It 

also slowed the runoff of inland waterways. The high tide at Tolchester Beach (Kent County) reached 4.35 feet above mean 

lower low water. Minor tidal flooding starts at 3.5 feet above mean lower low water. Moderate tidal flooding starts at 4.5 feet 

above mean lower low water. 

The unusually wet March was causing a flood of nutrients and sediment into Chesapeake Bay threatening the water quality. It 

was feared that it would cause algal blooms and cause fewer underwater grasses to grow. The heavy rain was caused by a low 

pressure system that moved from the Southern Plains on the morning of the 8th northeast into Iowa on the morning of the 9th, 

Michigan on the morning of the 10th and into the eastern Great Lakes by the morning of the 11th. This system was able to tap 

moisture from both the Gulf of Mexico and Atlantic Ocean and lift it over its frontal boundaries. The rain ended once the low's 

cold front moved through Maryland.

Several county roads across southern Scott County were impassible due to melting snow and runoff. 

Due to a very wet fall, and a deep snow pack by mid March, when temperatures began to rise and melt the snow, area streams, 

creeks and eventually rivers rose to minor, moderate, and major stage levels. 

During the onset of the snow melt, area streams, creeks and rivers had numerous ice jams that caused flooding across many 

areas in southern Minnesota. Road closures due to creeks and streams developed as early as Monday March 21st, and quickly 

spread across a large portion of southern Minnesota. By March 23rd, several areas along the Minnesota River between the 

southwestern suburbs of the Twin Cities, to Mankato started to close. This included Highways 93 and 19 near Henderson, and 

Scott County Road 9 near Jordan. In addition, Lac Qui Parle, Yellow Medicine, Brown, Watonwan, Blue Earth, Sibley, Scott 

and McLeod Counties had several county roads closed or impassable by Wednesday March 23rd. 

A large storm system on March 22nd and 23rd dropped on average one half to 1.50 inches of liquid precipitation across the 

area. However, as much colder air began to move south on the 23rd, all of the precipitation switched over to snow. 

By Wednesday, March 23rd, major river crossings in the Twin Cities began to close due to the flood waters; this included 

Highway 41 near Chaska and Highway 101 near Shakopee. In addition, more county roads started to close across southern 

Minnesota, and Highway 65 in Albert Lea shut down. 

The last week of March, most of the Minnesota River and its tributaries had their first crests. However, a cold spell the last 

week of March, caused the rivers to fall or hold steady as the runoff from the snow melt abated. 

Although ice jams were reported across the area, one ice jam on the Seven Mile Creek near St. Peter, resulted in a fatality when 

a MNDOT worker tried to clear the ice jam and his Backhoe tipped over and fell into the area where Seven Mile Creek flows 

into the Minnesota River.

afternoon into the evening, winds abruptly switched to the north-northwest and gusted from 50 to 60 mph. Combined with light 

falling snow, visibilities quickly dropped below a quarter mile in whiteout conditions. Despite the warnings that had been 

issued earlier, many people were caught off guard. Interstate 94 was closed from Fargo to Dickinson, Interstate 29 was closed

of farmland. Numerous roads in the county were flooded. Some of the roads were closed, and some were washed out in spots. 

The flooding onset was rapid for a snow melt flood due to high water and groundwater levels from record precipitation in the

2010. 

Melting of a very heavy winter snow cover caused flooding of small streams and lakes in southwest Minnesota. The flooding 

included farmland and other lowlands, with some roads flooded and damaged. High water and groundwater levels resulting 

from record precipitation in the previous year contributed to the rapid onset of the flooding. The flooding began with warm 

weather which arrived at the middle of the month, and continued generally through the end of the month, although flooding 

abated on some rivers and streams before the end of the month.

A deep snowpack began to melt in mid-March and brought flooding across west central Minnesota through the end of the 

month. Several of the creeks flooded including Twelve Mile Creek in Traverse county. Twelve Mile Creek rose to almost 3 

feet above flood stage towards the end of the month. Many county and township roads were flooded along with many acres of 

crop and pastureland. Due to the damage from the flooding, a Presidential Disaster was declared for both Big Stone and 

Traverse counties. The damage was estimated from 500 thousand to 1 million dollars. The snow melt and subsequent flooding 

continued into April.

Magby Creek flooded out of its banks and flooded two homes in the Masonic subdivision. This water flooded the homes after 

the rain was over. 

A potent storm system combined with abundant moisture over the ArkLaMiss region to bring nearly 24 hours of showers and 

thunderstorms, beginning during the day March 8th and continuing through the early morning hours of March 9th. With rich 

moisture flowing north from the Gulf of Mexico, many of the storms were efficient rain producers, which brought the risk of 

flash flooding and river flooding to the area. Many locations along and southeast of the Natchez Trace Parkway corridor had 

already seen as much as 3 to 4 inches of rain just 3 to 4 days prior to this event. Along with the flooding, ample wind shear and 

strong forcing from an upper disturbance and approaching cold front brought a risk for severe thunderstorms. The best 

combination of wind shear and instability was located south of Interstate 20. As the upper disturbance moved closer to the 

region, some storms became severe with a few storms exhibiting small, tight rotation on radar. Two tornadoes occurred during 

this event and they were both in Hinds County. 

Showers began to affect the ArkLaMiss region during the morning of the 8th. These showers increased in coverage and 

intensity during the afternoon and evening hours. Thunderstorms moved repeatedly over the same locations, which allowed 

rainfall amounts to add up quickly. Storm total rainfall ranged from 4 to 7 inches of rain, especially across southeast and eastern 

portions of the forecast area. Numerous flash flood warnings were issued and reports of water covering roadways, along with 

water rescues were received. This additional rainfall rose water levels on area rivers, causing several to go above flood stage.

March 2011 


An area of low pressure developed over southeast Louisiana and moved east along a warm front which stretched across 

southeast Mississippi. This eventually caused a strong cold front to sweep through the region with numerous showers and 

thunderstorms. This storm system combined with cold temperatures aloft and triggered severe storms that produced quite a bit 

of hail along with some scattered reports of wind damage. Multiple reports of golf ball sized hail occurred with the largest hail 

size being tennis ball size. The most intense storm occurred over central sections of Mississippi, roughly across northeast 

Copiah County and northwest Simpson County. Here, a very intense downburst occurred with winds up to 110 mph which 

downed dozens of trees. Large hail was wind driven and many trees were stripped of there leaves. Outside of the severe storms, 

several storms moved over the same locations which resulted in heavy rainfall which led to some flash flooding generally 

within the I-20 corridor.

On March 17th, spotters reported the middle fork of the Lodgepole Creek was flooding with water over the roads and closing 

roads in northwest Garfield county. Also, the Steve Forks Creek and Sand Creeks were running out of their banks causing 

flooding in adjacent fields. Later in the afternoon of the 17th, Garfield County Sheriff reported a couple of ice jams upstream of 

Jordan on the Big Dry Creek. This caused a flood threat for the town of Jordan at 0157 on March 18th, flooding parts of the 

town. Garfield County DES reported that one of the ice jams moved downstream. At 1317 MST March 20th, water levels on 

the Sand Creek, Little Dry Creek and Big Dry Creek east of Jordan were high due to snowmelt and some cases were running 

across roads (also with blocked culverts). 

Above normal snowmelt and ice jamming contributed to flooding in Garfield county.

A cold front accompanied by a line of showers and thunderstorms moved through Billings during the early morning hours of 

the 11th. The thunderstorms produced a microburst with winds estimated at 80 mph around 1AM MST in the Billings Heights 

causing a narrow corridor of damage. 

A damage assessment team from the National Weather Service in Billings traveled to El Rancho Drive in the High Sierra 

Subdivision in the Billings Heights. They found numerous vinyl fences blown down, some roof shingle and siding damage, 

bent street signs, tossed around trampolines and downed free-standing basketball hoops. 

The damage pattern, which showed objects blown down from Northwest to Southeast, was consistent with severe thunderstorm

A strong upper level trough and associated cold front pushed across the region during the afternoon and evening of March 22. 

The upper level system caused low pressure to deepen over eastern Nebraska/northeast Kansas with a warm front extending 

northeast from the low into east central Nebraska and southwest Iowa. By mid afternoon, ahead of the cold front and south of 

the warm front, temperatures climbed into the upper 70s to lower 80s and dew point temperatures reached the upper 50s. The 

instability and shear near the low and warm front created a favorable environment for supercell development, a few of which 

produced damaging hail and at least 3 tornadoes in the area.

After another bout of snow and colder temperatures, additional ice jamming developed on the Platte River during Sunday 

morning of February 27th, but this time was a bit further downstream, affecting portions of Merrick and Polk Counties. The ice 

was jammed under the Highway 92 bridge crossing the Platte River approximately 2 miles south of Clarks, and was reported to 

have extended back west by as much as 3 miles. Residents near the river east of the bridge successfully protected their homes 

by building an earthen berm ahead of the rising water, but a mile and half section of Prairie Island Road on the west side of the 

bridge did have to be closed as it became covered in water. There was little change in conditions for several days into the 

beginning of March, but the ice jam finally broke free the morning of March 4th, resulting in a quick drop in the river height.

NEBRASKA, South Central 

Between the pre-dawn hours of Monday the 7th and the morning of Wednesday the 9th, a rather complex, two-part snow event 

affected South Central Nebraska. In the end, the highest storm total snowfall amounts of 4-6 inches focused primarily north of 

Interstate 80, although some locations roughly west of a line from Kearney to Beaver City also picked up 3 to isolated 5 inch 

amounts. In contrast, most areas generally east of a line from Franklin to Hastings only measured from a dusting up to around 2 

inches. For all areas, the majority of snow fell during the first 24 hours of the event on the 7th. Although most snow 

accumulations fell on the 7th-8th, one last band of light snow drifted across central and eastern sections of the area on the 

morning of the 9th, dropping as much as 0.7-inch at Grand Island. 

Needless to say, this winter storm did not turn out to be nearly as significant as originally forecast a few days prior to the onset. 

For several days in advance, a number of computer model forecasts insisted that much of the area would see at least 8-12 inches 

of snow, along with fairly strong north winds. However, two primary factors combined to make this event a snow dud for much 

of the area. First of all, the upper level low pressure systems that provided the forcing for snowfall came into the Central Plains 

in a far less-organized fashion than first predicted. This prevented a persistent, concentrated swath of snow from forming, 

especially with the second part of the system on Tuesday the 8th. The weaker system also kept winds from becoming very 

strong, with sustained speeds mainly holding at or below 20-25 MPH. Secondly, the easterly surface winds that prevailed 

during this time actually drew slightly warmer air into roughly the eastern half of South Central Nebraska, bringing 

temperatures into the 32-38 degree range, which greatly hindered snow accumulation or changed precipitation over to light rain 

altogether.

This Tuesday afternoon featured one of the first strong thunderstorms of 2011 in South Central Nebraska, mainly affecting 

locations near the Kansas border in Franklin County with reports of dime to nickel size hail. This storm developed along the 

southern edge of a line of weak showers moving east out of Southwest Nebraska, generally tied to an area of low to mid level 

frontogenesis behind a surface cold front well off to the east. As these showers drifted into the area, the newly developed 

thunderstorm on the southern end become strong, taking advantage of modest elevated instability only around 500 J/kg but very 

strong deep-layer wind shear of at least 60-70 knots. Near Franklin, the ground was reported to be covered white with small 

hail.

Starting during the late evening hours on Thursday the 24th, but primarily during the pre-dawn hours on Friday the 25th, a 

quick-hitting low pressure system brought an average of 3 to 5 inches of wet, slushy snow to northern portions of South Central 

Nebraska, primarily targeting counties north of Interstate 80, and east of Highway 281. Some of the highest reported totals for 

the 24-hour period ending on the morning of the 25th included 5 inches at both Osceola and Benedict, and 4 inches at Fullerton 

and York. In contrast, only minimal accumulations from a trace to around 1 inch fell across areas generally south of a 

Gothenburg-Hastings-Geneva line, partly due to warmer temperatures that kept some of the precipitation as light rain. The 

instigator for this slushy snow event was a low amplitude mid level shortwave trough passing through the region, which 

generated a fairly pronounced zone of low to mid level isentropic lift and warm air advection. As it turned out, this snow event 

served as the opening act to an unseasonably cold 5-day stretch lasting through the 29th, during which most of South Central 

Nebraska endured high temperatures only in the 30s each day, along with a few rounds of light snow. For most of the area, this 

was the overall coldest last week of March since 1987.

On Saturday morning, March 5th, a frontal system was located over the Ohio and Mississippi River Valleys. Ahead of the 

front, south to southwest winds ushered in some very mild air. Temperatures across most of southern and central New 

Hampshire warmed into the lower 50s during the day and remained well above freezing Saturday night. At 7 AM Sunday, 

temperatures were in the upper 40s to lower 50s across the state. By Sunday morning, March 6th, the front had moved east to 

the Appalachians and the strong southerly flow ahead of the system continued to bring mild temperatures and tropical moisture 

northeast from the Gulf of Mexico and southern Atlantic Ocean. Temperatures Sunday climbed into the middle 50s across the 

state. An area of low pressure began to develop over the southeastern states Sunday and then moved northeast along the 

frontal boundary Sunday night and Monday as it intensified rapidly. Light rain, associated with the approaching cold front 

began to fall Sunday morning. The precipitation became heavy by late afternoon as the intensifying area of low pressure 

approached New Hampshire from the south. At the same time, colder air started funneling into the state from the north and 

changed the rain to snow across Coos County. As the colder air continued to move southward late Sunday afternoon and 

evening, the rain changed to freezing rain across Grafton County and the higher elevations of Sullivan and Merrimack 

Counties. Across the state, heavy snow, freezing rain and rain continued through the night and finally ended early Monday 

afternoon, March 7th. In addition to the precipitation, strong and gusty winds developed across the region Sunday night and 

continued Monday. Winds gusted to about 20 to 25 mph across much of southern New Hampshire during the storm with gusts 

of about 30 to 45 mph as the storm moved east Monday afternoon. 

Across northern New Hampshire, snowfall accumulations from the storm ranged from 8 to 22 inches. In Grafton and Sullivan 

Counties, ice accretions of ¼ inch were reported, although local amounts were likely higher. This ice, in combination with 

the wind, brought down trees and tree limbs across Grafton and Sullivan Counties leading to numerous power outages and 

more than $700,000 in damage. 

Rainfall amounts across the southern part of the state were generally in the 1 to 3 inch range, with locally higher amounts. In 

addition, melting snow, due to the mild temperatures, contributed to the runoff from the storm. The rainfall and melting snow 

caused river levels to rise which caused river ice to break and move downstream. Several breakup ice jams occurred, with the 

most notable jams being in West Claremont on the Sugar River and in Plymouth on the Pemigewasset River. Other jams 

occurred on the Baker and Contoocook Rivers. These ice jams remained in place for several days.

Major flooding occurred in eastern Morris County and started on the 7th. Sections of the Pompton and Passaic Rivers never had 

a chance to recede before the next round of heavy rain arrived on the 10th. The worst flooding and damaged occurred after the 

second round of heavy rain. Nevertheless, about twenty homes were evacuated in Lincoln Park when the Pompton River 

crested the first time. During the second and more serious round of flooding, over 1,000 homes were affected by flood waters in 

Pequannock and Lincoln Park. The American Red Cross and Salvation Army distributed nearly 4,000 meals and 4,500 snacks. 

The American Red Cross also distributed nearly 700 clean-up kits and 200 bulk items. Pumps, fans, wet vacs and dehumidifiers 

were in demand. In Pequannock, 1,300 homes were affected by flood waters and around 100 homes were damaged. About 

1,500 people were evacuated and 2,000 residents affected by the flood waters. The hardest hit area was the lower village south 

of Jackson Avenue, by Madison Avenue and east of the Newark-Pompton Turnpike. New Jersey State Route 23 was closed and 

was flooded at its intersection with Jackson Avenue. The National Guard dispatched five high water rescue vehicles. 

Barricades and bagging helped minimize flood damage to a shopping center off of New Jersey State Route 23. In Lincoln Park, 

twelve homes were evacuated and 200 homes were affected by flood waters. A shelter was opened in the borough. Riveredge 

Road was under three feet of water. U.S. Route 202 was closed. Firefighters needed a boat to fight one fire. 

The Passaic River at Pine Brook had major flooding with its second crest and was above its 19 foot flood stage from 430 p.m. 

EST on the 7th through 1245 a.m. EDT on the 18th. The first crest was 20.09 feet at 9 p.m. EST on the 8th. The next crest was

feet at 1115 p.m. EDT on the 12th. 

The Pompton River along the Morris County border had major flooding also and the lower part of the river did not fall below 

flood stage before the next heavy rain event arrived on the 10th. The Pompton River at Midwood Road rose above its 7.5 foot 

flood stage at 150 a.m. EST on the 7th. It had major flooding occur twice. Its first crest was 12.6 feet at 10 p.m. EST on the 7th. 

The second crest reached 13.3 feet at 250 p.m. EST on the 11th before the gage became submerged. The actual crest in all 

likelihood was higher. Farther downstream, the Pompton River at the Mountainview Bridge had a major flood crest of 14.1 feet

6th. Precipitation ended briefly as snow over the higher terrain of northwest New Jersey during the early morning on the 7th. In 

Eastern Morris County, sections of the Pompton and Pasaic Rivers were still above flood stage when another heavy rain event 

occurred from the early morning of the 10th into the morning on the 11th. An additional 2 to 5 inches of rain fell and 

exacerbated and caused major flooding on both rivers. Governor Christopher Christie declared a state of emergency before the 

start of the second round of heavy rain on March 9th. Some locations on those rivers did not fall below flood stage until after 

Eastern Daylight Time began (on March 13th). Throughout the state, 683 dwellings were affected by both flooding events and 

207 suffered at least major damage.

A mix of sleet and freezing rain fell across the higher terrain of Sussex County during the early morning of the 10th. Ice 

accretions were generally less than one tenth of an inch. Temperatures were still around freezing as the precipitation moved 

into the county just after Midnight EST on the 10th. Warmer air continued to move in at the surface on southeast winds and 

after 8 a.m. EST, all locations had temperatures above freezing. The wintry mix was caused by the combination of a warm 

front advancing toward New Jersey from the South and some leftover cold air at the surface provided by a departing high 

pressure system over the Canadian Maritimes.

Strong southeast winds channeled up the Delaware Bay and also affected southeast New Jersey during the late afternoon and 

early evening of the 10th. Peak wind gusts averaged around 50 mph. The combination of the wind and heavy rain that loosened 

the soil caused weak trees, tree limbs and power lines to be knocked down. From the combination of the wind in the south and 

the flooding in the north, throughout the state, about 4,500 homes and businesses lost power. In Salem County, trees were 

knocked down across five roadways and stop signs were knocked down on two other roadways. Peak wind gusts included 49 

mph in Bivalve (Cumberland County) and 47 mph at the Atlantic City International Airport. The southeast winds also help 

cause pockets of minor tidal flooding along the ocean in southeast New Jersey at the time of the late evening high tide. In 

Atlantic City (Atlantic County), the high tide reached 6.06 feet above mean lower low water. Minor tidal flooding starts at 6.0 

feet above mean lower low water. The strong winds were caused by the pressure difference between a strong high pressure 

system over the Canadian Maritimes and an approaching frontal boundary from the Ohio Valley. This difference was at its 

strongest during the late afternoon and evening of the 10th and lessened after a warm front moved through southern New 

Jersey.

For the second time within a week heavy rain fell across New Jersey, especially the northern half. An additional 2 to 5 inches of 

precipitation fell and caused continued flooding in the Passaic Basin and renewed flooding on the Delaware and Raritan Rivers. 

Snowmelt in the upper reaches of the Delaware Basin contributed to the flooding. Major flooding occurred within the Passaic 

Basin, mostly minor flooding occurred on the Delaware River and in the Raritan Basin. Governor Chris Christie declared a 

state of emergency before the start of the second round of heavy rain on March 9th. Throughout the state, 683 dwellings were 

affected by both flooding events and 207 suffered at least major damage. The second round of rain started during the early 

morning of the 10th, fell heavy at times during the daylight hours and evening on the 10th and ended between 4 a.m. and 8 a.m. 

EST on the morning on the 11th. Eastern Daylight Time started on the morning of the 13th. Some of the rivers began flooding

South of Trenton on the Delaware River, the combination of the up the Delaware Bay and River wind flow and freshwater 

runoff produced minor tidal flooding along the river and tidal sections of its tributaries during the late afternoon high tide cycle 

on the 10th and the early morning high tide cycle on the 11th. The highest tide occurred on the 11th and reached 8.93 feet 

above mean lower low water in Philadelphia, Pennsylvania. Minor tidal flooding starts at 8.20 feet above mean lower low 

water. 

The heavy rain was caused by a low pressure system that moved from the Southern Plains on the morning of the 8th northeast 

into Iowa on the morning of the 9th, Michigan on the morning of the 10th and into the eastern Great Lakes by the morning of 

the 11th. This system was able to tap moisture from both the Gulf of Mexico and Atlantic Ocean and lift it over its frontal 

boundaries. The deep southeast flow was able to enhance the precipitation further over the higher terrain of northwest New 

Jersey. The rain ended once the low's occluded front moved through New Jersey.

A wintry mix of precipitation, mainly in the form of snow, fell across Northwest New Jersey during the morning of the 21st. It 

impacted the Monday morning commute, especially on untreated roadways over the higher terrain. Snow accumulations 

averaged 1 to 5 inches with the highest amounts in Sussex County. Ice accretions were negligible. Precipitation started as rain 

around 4 a.m. EDT on the 21st and changed to all snow around one hour later as the precipitation intensity increased. The 

snow then changed briefly back to sleet and then rain around 9 a.m. EDT, except there were some pockets of freezing rain in 

Sussex County. The precipitation ended around 11 a.m. EDT on the 21st. While the duration of snow was similar in the five 

northwest New Jersey counties, the highest accumulations occurred over the higher terrain of Morris, Warren and Sussex 

Counties where temperatures were closer to or at freezing when the snow fell. 

Snowfall included 4.7 inches in Wantage (Sussex County), 3.7 inches in Randolph (Morris County), 3.5 inches in Flanders 

(Morris County), 3.3 inches in Lake Hopatcong (Morris County), 3.0 inches in Blairstown (Warren County), 1.8 inches in 

Newton (Sussex County), 1.5 inches in Holland (Hunterdon County) and Hardyston (Sussex County), 1.0 inch at White House

(Warren County), 0.5 inches in Bernards Township (Somerset County) and 0.3 inches in Flemington (Hunterdon County). 

The wintry mix of precipitation was caused by a warm front from the Ohio Valley associated with a low pressure system that 

moved through the eastern Great Lakes and into the Saint Lawrence Valley on the 21st. The precipitation ended as the warm 

front neared New Jersey.

A protracted winter storm affected northwest New Jersey from just after Midnight on the 23rd into the early morning on the 

24th and brought two shots of wintry weather during the early morning and overnight on the 23rd. Snow accumulations 

averaged 2 to 10 inches in northwest New Jersey and 1 to 4 inches in the Raritan Basin. A band of heavier snow that fell just 

before the morning commute on the 23rd across southern Sussex County, northern Warren County and western Morris County 

accounted for the highest snowfall totals. Ice accretions averaged a tenth of an inch or less, mainly affecting the Raritan Basin. 

In Sussex County, the precipitation started as snow around 3 a.m. EDT on the 23rd and fell at its heaviest during the event 

during the pre-dawn hours. Precipitation mixed with sleet at times during the daylight hours on the 23rd. The snow ended 

around 4 a.m. EDT on the 24th. Over the rest of northwest New Jersey as well as the Raritan Basin, precipitation started as rain 

shortly after Midnight EDT on the 23rd and changed to snow about an hour later as the intensity increased. The band of heavier 

snow also affected Morris and Warren Counties through 7 a.m. EDT on the 23rd. In Warren and Morris Counties, the snowfall 

intensity during the rest of the daylight hours was light and mixed with sleet and rain at times. In the Raritan Basin, the snow 

changed to rain around 9 a.m. EDT. Precipitation changed back to all snow in Warren and Morris Counties during the evening 

of the 23rd and a wintry mix in Hunterdon and Somerset Counties in the Raritan Basin. Precipitation ended by 6 a.m. EDT on 

the 24th. Untreated roadways were treacherous, especially during the early morning on the 23rd when the heavier snow was 

falling in Northwest New Jersey. 

Representative snowfall included 11.0 inches in Marcella (Morris County), 10.0 inches in Green Pond (Morris County), 9.5 

inches in Milton (Morris County), 9.1 inches in Blairstown (Warren County), 8.8 inches in Andover (Sussex County), 8.0

inches in Wertsville (Hunterdon County), 2.1 inches in Flemington (Hunterdon County), 2.2 inches in Stockton (Hunterdon 

County), 2.0 inches in Cheesequake (Middlesex County), Somerville (Somerset County) and Phillipsburg (Warren County) and 

1.9 inches in Hillsborough and Montgomery (both Somerset County). 

The wintry weather was caused by a pair of low pressure systems that moved from Iowa on the evening of the 22nd east and 

reached the central Ohio Valley on the morning of the 23rd, near Pittsburgh Pennsylvania during the afternoon of the 23rd and 

passed off the Delmarva and Virginia coasts overnight on the 23rd.

A cold front moved gradually southeastward across the region during the day on Sunday, March 6th, as a wave of low pressure 

moved northeastward along the boundary Sunday night into Monday, March 7th. Colder air was drawn into the area in the 

wake of the boundary, changing the ongoing rain to mixed precipitation, freezing rain and sleet, then to snow. The period of 

mixed precipitation only lasted a couple hours, except for across a portion of the Capital District, western Albany, southern 

Saratoga and Rensselaer counties, where a prolonged period of mostly sleet occurred. 

Heavy snow accumulated across the western Adirondacks, Mohawk and Schoharie Valleys, the central and eastern Catskills, 

the Lake George Saratoga region, and across the Capital District. One to 2 feet of snow was reported across the southern 

Adirondacks and Mohawk Valley, 8 to 18 inches across the Lake George Saratoga region, Helderbergs, and Schoharie Valley, 

with 5 to 8 inches of snow and sleet across the Capital District on top of the quarter to about a half of an inch of ice accretion. 

Across portions of the southern Taconics, mainly above 500 feet, pockets of freezing rain led to significant ice accretion of up 

to one inch. This led to downed trees, power lines and power poles, and resulted in power outages. The Towns of Amenia, 

Northeast, and a portion of Dover were hardest hit by the ice. 

The snow came down heavy at times, with snowfall rates of 1 to 2 inches per hour. In addition, brisk northerly winds resulted 

in blowing and drifting of the snow during the morning hours. This combination of heavy snow, along with blowing and 

drifting of the snow made it difficult for snow plows to clear the roads. The heavy snow and sleet resulted in widespread power 

outages, school closures, traffic accidents and even a few roof collapses. A partial roof collapse occurred at the Hero/Beech-Nut 

facility in the Florida Industrial Park in Florida. In addition, the third floor of an unoccupied brick building collapsed in

Record flooding occurred on the Hudson River at North Creek as a result of an ice jam. The ice jam extended from about 1 1/2 

miles downriver from the Route 28N Bridge and northward about 3 miles. 

An ice jam began to form on Monday, March 7th, near the Route 28N Bridge in North Creek. Water backed up from the ice 

jam began flooding Old River Road early Thursday morning, March 10th, prompting the evacuation of some residents and the 

closure of the road. The water began to recede early Sunday afternoon, March 13th, when the ice jam released and moved 

downstream. 

The ice jam moved down river and ripped trees from the river bank. The jam became lodged along the Route 418 Bridge in the 

town of Thurman Sunday evening, March 13th, with water levels receding behind the jam. Only some minor flooding was 

reported at the Warren County Fish Hatchery in Warrensburg, and four fairways went under water at Cronin's Golf Resort

Another bout of heavy rainfall occurred across east central New York Thursday, March 10th, into Friday, March 11th. 

Generally 1 to 3 inches fell across the area, with locally higher amounts of 4 to 5 1/2 inches reported across portions of the 

eastern Catskills. In addition, mild temperatures resulted in snowmelt. The combination of the heavy rainfall, and runoff from 

the snowmelt caused flooding of rivers, streams, creeks, roads, and some urban low lying areas. Moderate flooding occurred 

along the Esopus and Schoharie Creeks. 

An ice jam formed on the Mohawk River which resulted in flooding along the river in parts of Albany, Saratoga and 

Schenectady counties. The combination of increased flow from the upper Mohawk Basin and out of the Schoharie Creek due to 

runoff from the heavy rainfall and snowmelt caused ice to move. On Friday, March 11th, an ice jam in place in Schenectady 

County at Lock 9 and Lock 8 broke up and moved downstream. Another ice jam formed and extended from the Twin Bridges 

back towards Lock 7 in Niskayuna and caused flooding of some properties and houses along the river. The ice jam broke up 

and moved down river without any additional flooding on Sunday, March 13th.

NEW YORK, North 

On March 6th, this storm began to move north across the southeast and Mid-Atlantic states along a slow moving cold front 

positioned across New York south to Florida. More heavy rainfall, flooding and severe weather accompanied this system. In 

northern New York, heavy rainfall and temperatures in the 40s preceded the cold front. However, as the cold front crept across 

northern New York during the morning hours, temperatures fell 12-15 degrees within an hour and heavy rain changed to heavy 

sleet and wet snow. 

At the same time, rapid snow melt and heavy rainfall accounted for area ice-covered rivers to swell and cause ice flows. A 

significant ice jam formed in the Keene Valley between Jay and Keene that resulted in moderate to major flooding of numerous 

homes and forced evacuations during a major snowstorm. 

Heavy snow continued from the afternoon of March 6th to midday on March 7th with the heaviest occurring in the early 

morning hours of the 7th with snowfall rates of 1 to 3 inches per hour. Total snowfall accumulations ranged from 5 to 10 inches 

in the St. Lawrence River Valley to 18 to 30 inches across much of the Adirondacks and Champlain Valley. 

Most roads were impassable with numerous accidents and stuck vehicles. Nearly 5000 customers lost electrical power, nearly 

all school districts were closed on the 7th along with local/state government as State of Emergencies were declared in Clinton

A significant severe winter weather event occurred across much of west and all of central North Dakota March 11th through 

early March 12th. 

An Alberta Clipper rapidly intensified as it moved east-southeast into the Northern Plains in response to a strong upper level jet 

streak amplifying the clipper's associated mid level trough. Warm air advection ahead of the clipper resulted in the initial 

precipitation type to fall as rain. As the precipitation was mainly orientated along the clipper's cold front, a quick transition 

from rain to all snow occurred with the frontal passage. Storm total snow accumulations with this storm ranged from two to 

five inches northwest and central. 

The main impact from this storm was the sudden onset and prolonged period of intense winds generated along and behind the 

cold front. Sustained winds in excess of 40 mph, with gusts to around 70 mph, developed west during the morning and spread 

east in the afternoon, then persisting through evening. When combined with the snow, severe blizzard conditions quickly 

became widespread, significantly impacting travel. In addition, temperatures initially above freezing fell into the 20s behind 

the front, turning wet and slushy roads into ice. 

Across southwest North Dakota, very little precipitation fell and the main impact was high wind. 

The violent and fast moving nature of this storm, combined with extremely icy road surfaces, resulted in dangerous if not 

impossible travel conditions in white out conditions. Numerous travel advisories and road closures were in effect, including the 

closure of Interstate 94 from Dickinson to Fargo, and Highway 83 from Bismarck to Minot. Several hundred motorists were 

stranded along minor and major roadways. Many accidents occurred. One in Sioux County involved injury. This blizzard 

caused unprecedented demand on law enforcement and emergency services, and required the North Dakota National Guard to 

be activated to assist in rescuing stranded motorists.

NORTH DAKOTA, Central and West 

Warmer air surging north ahead of this storm system resulted in a wintry mix of rain, freezing rain, and sleet across much of the 

west and south central portions of the state at first, while all snow fell over the north central. Colder air pushing south 

eventually transitioned the precipitation to all snow. While there were some ice accumulations across the south, ice impacts 

were minor. 

Heavy snow fell from west central North Dakota, through much of the south central and James River Basin region. Storm total 

snowfall amounts within this band ranged from eight inches to one foot, with locally higher amounts including 18.2 inches near 

Beulah. In addition to the snow, wind gusts up to 45 mph developed across far northwest and all of north central North Dakota 

resulting in several hours of blizzard conditions. 

Numerous travel advisories and several road closures resulted from this storm, including the closure of Interstate 94 from 

Bismarck to Fargo, Highway 83 from Bismarck to the Canadian border, and Highway 2 from Berthold to Rugby. 

This was a prolonged and very complicated storm to warn for as potential was high for various types of warning criteria to be 

met.

This late winter blizzard was much like some of the killer blizzards of the past. Most of Friday the 11th was beautiful for mid 

March, with steady south winds and temperatures in the upper 30s to middle 40s. After beginning the month with highs in the 

teens and low 20s, the warmth of the day lulled many people into not believing that a blizzard was coming. By late in the 

afternoon into the evening, winds abruptly switched to the north-northwest and gusted from 50 to 60 mph. Combined with light 

falling snow, visibilities quickly dropped below a quarter mile in whiteout conditions. Despite the warnings that had been 

issued earlier, many people were caught off guard. Interstate 94 was closed from Fargo to Dickinson, Interstate 29 was closed 

from the Canadian border to the South Dakota border, and U. S. Highway 2 was closed from Grand Forks to Devils Lake.

of weather conditions occurred to the north of the surface low. Showers with embedded thunder changed to snow with 

embedded thunder as far north as the central Red River Valley. Freezing rain fell over portions of Richland County, while other 

areas saw up to an inch of sleet. At least six inches of snow fell across most of the area, but the Highway 200 corridor from 

Finley to Mayville to Hillsboro picked up nearly two feet of snow. The adverse weather shut down Interstate 94 from Fargo to 

Bismarck and Interstate 29 between Grand Forks and Fargo.

A deepening low pressure system, originating from the southern plains, moved towards the western Great Lakes on Wednesday 

March 9th. A wintry mix of precipitation changed over to all rain as the warm front associated with this system pushed across 

the region on Wednesday morning. Periods of moderate to heavy rain continued through the passage of the upper level trough 

late Thursday. With much of the region already saturated from previous rainfall over the past 2 weeks many streams and creeks 

were already elevated. The additional 1 to 2 inches of rainfall resulted in my streams and creeks gong out of their banks 

throughout east central Ohio, western Pennsylvania and northern West Virginia. As the low progressed to the east rain changed 

back to snow bringing 4 to 5 inches of heavy wet snow to east central Ohio and northwestern Pennsylvania, mainly north of I-

An area of low pressure over western Pennsylvania during the afternoon of March 10th moved north to near Buffalo during the 

evening hours. The low then lingered over southeastern Ontario through the early afternoon hours of the 11th while slowly 

weakening. Rain associated with this low changed to snow during the evening hours of the 10th. Periods of moderate to heavy 

snow were reported from around midnight on the 11th through midday. The snow ended from west to east during the afternoon 

hours. A brief period of freezing drizzle or very light freezing rain was reported over far northeastern Ohio just as the snow 

ended. The heaviest snow fell along and north of the Ohio Turnpike from Lorain County east across the Cleveland 

Metropolitan area and into Northeast Ohio. Snowfall totals ranged from around six inches in Lorain County to more than 12 

inches over portions of Lake, Geauga and Ashtabula County. Peak totals for each of the counties affected included: 18.7 inches 

at Madison in Lake County; 15.0 inches at Pierpont in Ashtabula County; 13.0 inches at Thompson in Geauga County; 11.1 

inches at Lyndhurst in Cuyahoga County; 9.0 inches at Warren in Trumbull County and 7.5 inches at Elyria in Lorain County. 

North to northwest winds gusting to as much as 25 mph accompanied the snow and caused some blowing and drifting initially. 

Temperatures eventually warmed to near the freezing mark resulting in less blowing but very wet and heavy snow. Travel was

common. Including this episode, the accumulative affects of 5 significant rain events since February 21st, caused the Ohio 

River to flood. The crest along the Ohio River was mostly 2 to 6 feet above the assigned flood stages. The crest occurred late 

on the 12th into the morning hours of the 13th. Along many reaches, it was the highest stage on the Ohio River since 2005. 

Some of the flood gates were installed in the Ironton floodwall, forcing a school to be canceled for a few days. 

The crest of 49 feet at Pomeroy did allow water to reach the businesses along Main Street. Water was about 6 inches to a foot 

inside the structures. However, damage was minimal. Inventory and personal property was moved to higher levels well in 

advance of the flood. The Pomeroy police chief said, the community knew what they needed to do, they knew what was 

expected, and they stuck together, and that's what separates us from other people. 

In Lawrence County, about 20 properties along the river had minor water problems. This was either water reaching around 

their homes, or into their garages and outbuildings. 

The other most significant impact was road closures along the entire reach of the river in southeast Ohio. This caused motorists 

to take alternate routes for a few days. In the wake of the high water, a few roads suffered slips from the saturated ground. 

Many of the flood prone parks and recreational areas along the river were also flooded, including some of their outbuildings. 

The unique feature about this flood, was the fact that there was very little headwater river or small small flooding in southeast 

Ohio. Leading into the Ohio River flood, only some minor stream flooding occurred along portions of some of the larger 

creeks, such as Raccoon Creek and the Little Muskingum River.

A prolonged period of unseasonably dry weather resulted in severe to extreme drought conditions to develop across much of 

east-central and southeastern Oklahoma during the month. During the month of March, the McAlester area received 0.52 inches 

of precipitation, making this month the driest March on record for the McAlester Regional Airport observing site. Most of 

southeastern Oklahoma received between five and twenty-five percent of the normal monthly precipitation for March. The 

unseasonably dry conditions in this part of the state extended back about a year as the past three months, six months, and 

twelve month periods are all the 2nd or 3rd driest on record, according to the Oklahoma Climatalogical Survey. 

The drought conditions contributed to a number of wildfires that occurred across a lot of eastern Oklahoma during the month.

Southerly winds of 20 to 30 mph, relative humidities below 20 percent, temperatures in the lower to middle 70s, and dormant 

vegetation promoted the spread of wildfire on the 11th. More than 40 wildfires were reported this day across eastern Oklahoma, 

burning around 8600 acres. Some of the larger wildfires occurred in Pushmataha County (1600 acres burned), Latimer County 

(1500 acres burned), and Le Flore County (1500 acres burned). 

Local fire departments along with Oklahoma Forestry Services, the Bureau of Indian Affairs and the Oklahoma Army National 

Guard battled those blazes, many of which threatened structures. Several outbuildings were burned but no homes were lost.

Strong wind, low relative humidities, warm temperatures, and dormant vegetation promoted the spread of wildfire on the 20th. 

Around 70 wildfires were reported this day across eastern Oklahoma burning more than 4000 acres. Some of the larger 

wildfires occurred in Pittsburg, Latimer, Haskell, Adair, and Pushmataha Counties. 

Local fire departments along with Oklahoma Forestry Services, the Bureau of Indian Affairs and the Oklahoma Army National 

Guard battled those blazes, many of which threatened structures. Several outbuildings were burned but no homes were lost.

A large wildfire began fifteen miles north of Guymon Oklahoma in Texas County around 0930 CST and consumed an 

estimated seven thousand and seven hundred acres. The wildfire was located on Road O and Mile 22. The cause of the wildfire 

was due to electrical lines which had shorted out in the strong winds. The wildfire destroyed two homes and also burned a 

couple of barns along with a Recreational Vehicle that was lived in and also some old scrap vehicles. There were no injuries 

reported. The wildfire was contained by 1900 CST about two miles past Oklahoma State Highway 136 with the aid of irrigated 

wheat fields.

The ongoing severe drought, D2, increased to D3, or extreme from southwest Oklahoma into central Oklahoma by later in the 

month. Much of Oklahoma continued with another month of below normal precipitation. In some cases, only a few hundredths 

were recorded for the entire 31 days. Since Thanksgiving, much of central and western Oklahoma has seen its driest 

precipitation totals since the 1920s and 30s. Much of the wheat crop planted in the fall had all but been declared a total loss. In 

fact, the conditions have gotten worse with the emergence of the wheat crop. The lack of precipitation has made for low water 

levels on stock ponds for livestock, and the water level in irrigation reservoirs used for crops is falling. The exact monetary 

number for the crop loss can not be determined, although it would probably be in the millions.

PENNSYLVANIA, East 

The COOP observer in Meyersdale estimated thunderstorm wind gusts near 60 mph. 

A low pressure system moved east from the Ohio Valley and triggered severe thunderstorms over southwest and south-central 

Pennsylvania. An unseasonably warm, unstable air mass resided across much of southwest Pennsylvania while cooler, more 

stable air was entrenched just east of the Allegheny Mountains. The instability combined with strong low and mid level wind 

shear produced an early-season convective environment that was favorable for damaging winds, large hail and isolated 

tornadoes over southwestern portions of the state. An EF2 tornado was confirmed outside of the State College CWA in 

Hempfield Township near Greensburg, PA in Westmoreland County. The storm that produced the tornado dropped golf-ball 

sized hail across northern Somerset County. The cooler air mass and weaker low level instability farther to the east limited the 

threat for damaging winds and isolated tornadoes across south-central Pennsylvania, but enough elevated instability was still 

present and supportive of large hail. Note: The estimated wind gust of 52 knots is equivalent to 60 mph.

A low pressure system that rode northnortheast along a cold frontal boundary produced a wintry mix of precipitation over the 

higher terrain of the Poconos from the late afternoon of the 6th through the night. The cold front moved through the Poconos 

during the afternoon of the 6th and temperatures dropped rapidly from the 50s. Rain started to change to freezing rain during 

the late afternoon on the 6th, then to sleet during the early evening of the 6th and finally to snow during the middle of the 

evening on the 6th. Snow fell overnight and ended between 5 a.m. and 6 a.m. EST on the 7th. While the wintry mix was 

occurring over the higher terrain, the valleys in the Poconos were having rain. Untreated roadways were slippery, especially 

since a one tenth to two tenths glazing of ice accrued initially on exposed surfaces. Snow and sleet accumulations included 3.0 

inches in Tobyhanna (Monroe County). The low pressure system on the cold front went southwestern Virginia at 1 p.m. EST

The pressure difference between a low pressure system that moved through New Jersey and into New England and a high

strong winds caused blowing and drifting snow. Peak wind gusts included 51 mph in Mount Pocono (Monroe County). The

accumulations were an inch or less and ice accretions reached up to one quarter of an inch. Temperatures were at or below 

freezing as the snow moved into the higher terrain of the Poconos during the evening of the 9th. As warmer air aloft continued

Because of the wintry weather overnight, a couple of school districts were closed in the Poconos, a couple of others had

For the second time within a week heavy rain fell across Eastern Pennsylvania. An additional 1.5 to 5 inches of precipitation 

fell and caused more widespread river, stream and poor drainage flooding including the Delaware, Lehigh and Schuylkill 

Rivers. On average moderate flooding occurred on the Lehigh River, with several locations recording top ten crests. Generally 

minor flooding occurred on the Delaware and Schuylkill Rivers. Snowmelt in the upper reaches of the Lehigh and Delaware 

Basins contributed ti the flooding. The worst reported damage was along the towpaths of the Lehigh River in Northampton 

County and the Delaware River in Bucks County. The heaviest precipitation amounts occurred in the Poconos, while the 

lightest precipitation amounts occurred in and around Philadelphia. Precipitation started during the late evening of the 9th, fell

Strong southeast winds channeled up the Delaware Bay during the evening of the 10th into Chester County. Peak wind gusts 

reached around 50 mph. The combination of the wind and heavy rain that loosened the soil caused weak trees, tree limbs and 

power lines to be knocked down. A tree was knocked down on Mortonville Road in East Fallowfield Township. Peak wind 

gusts included 49 mph in London Grove. The strong winds were caused by the pressure difference between a strong high 

pressure system over the Canadian Maritimes and an approaching frontal boundary from the Ohio Valley. This difference was 

at its strongest during the evening of the 10th and lessened after a warm front moved through the county later that evening.

Northampton County was affected by the one two combination of flooding along the Lehigh and Delaware Rivers. Flooding 

along these rivers also caused smaller streams and rivers to back up and flood. The flooding also caused considerable damage 

along the towpaths of both the Lehigh and Delaware River Canals. In Bethlehem, flooding along the Lehigh River forced the 

evacuation of about 100 residents along Wilson Avenue. While homes were not affected, sections of Wilson Avenue as well as 

Sculac and Farmersville Roads were impassable. Evacuations also occurred along the Monocacy Creek in Bethlehem's Colonial 

Industrial Quarter. In Easton, dozens of people were evacuated along Bushkill Drive after the Bushkill Creek flooded. Homes 

suffered basement flooding. Larry Holmes and Lehigh Drives were closed along the Lehigh River. Pennsylvania State Route 

611 South was closed along the Delaware River. Most of the roads were reopened on the 12th. 

Flooding along the Lehigh and Delaware Rivers caused considerable damage along the Lehigh Canal Towpath and the 

Delaware Canal Towpath into Bucks County. Along the Lehigh River, the damage was caused more by the strength of the 

current than the crest itself. Along the Lehigh River, in Walnutport a one hundred fifty foot section of a wall collapsed and a 

half mile section of the towpath was damaged. In Freemansburg, damage was described as worse than what occurred during the 

2004 flooding with Ivan. Trail surfaces were washed away and foundations exposed. The river scoured the towpath down to the 

original clay base from 1828. In Bethlehem, about seventy-five percent of a three mile stretch of the towpath was damaged. 

There were washouts on two bridges. The Delaware Canal State Park suffered surface damage and washouts and was closed 

from Easton to Wy Hit Tuk Park in Williams Township. From Wy Hit Tuk Park south to Upper Black Eddy in Bucks County, 

the trail was passable by foot, but not by bike.

A protracted winter storm affected the Poconos from around Midnight on the 23rd into the early morning on the 24th and 

brought two shots of wintry weather during the early morning and overnight on the 23rd. Snow accumulations averaged 3 to 10 

inches in the Poconos, 2 to 6 inches in the Lehigh Valley and 1 to 3 inches in upper Bucks County. Ice accretions averaged a 

tenth of an inch or less, greatest in the Lehigh Valley. Over the higher terrain of the Poconos, precipitation started as snow 

around Midnight EDT on the 23rd and fell at its heaviest during the event during the pre-dawn hours as a band of heavier snow 

affected northeastern Carbon County and most of Monroe County. Precipitation briefly changed to freezing rain during the

and Tobyhanna (Monroe County), 2.0 inches in Palmerton (Carbon County) and 0.5 inches in Jim Thorpe (Carbon County). 

The snow was caused by a pair of low pressure systems that formed over the southeastern United States. The first one reached 

the Delmarva coastal waters during the early evening of March 31st and weakened as the second low pressure system exited the 

Georgia coast. At 2 a.m. EDT on April 1st, the second low pressure system reached the North Carolina coastal waters and had 

become the stronger of the two lows. It continued to intensify and move northeast and at 8 a.m. EDT on April 1st, it reached

Counties. A peak total of 13.1 inches was measured at Franklin Center in Erie County with a peak of 12.0 inches at 

Conneautville in Crawford County. North to northwest winds gusting to as much as 25 mph accompanied the snow and caused 

some blowing and drifting initially. Temperatures eventually warmed to near the freezing mark resulting in less blowing but 

very wet and heavy snow. Travel was difficult during this storm and many accidents were reported. Many school districts either

moisture into the area ahead of the front. The combination of the abundant moisture and the cold front produced widespread 

showers and thunderstorms over the region. Some of the thunderstorms produced heavy rain which caused flash flooding. 

Large hail was also reported with a few storms.

A strong La Nina has caused the severe to extreme drought conditions to expand across West Central Texas through March. 

Precipitation estimates indicated that many locations across the area were approximately 6 to 12 inches below normal in rainfall 

since last October. 

As warm, dry and windy conditions continued to deplete soil moisture, wildfire was a big concern in all areas. Dry land wheat 

remained in poor condition due to lack of moisture, but irrigated fields were doing well.

The National Weather Service conducted a storm survey in Red River County, Texas, and concluded that storm damage was 

the result of an EF1 tornado. The tornado touched down at around 515 pm CST, approximately 8 miles west of Clarksville, 

Texas, along U.S. Hwy. 82 where it knocked down several small trees. The tornado tracked east-northeast crossing CR 2123 

where it damaged several trees. It then crossed CR 2161 northwest of Clarksville damaging trees along the road. The damage 

up to CR 2161 was all EF0. Once the tornado reached the north side of Clarksville, it intensified and widened to its widest 

point. The tornado crossed through a neighborhood north of Clarksville on the west side of Hwy. 37 where approximately a 

dozen homes sustained minor damage to their roofs, awnings, or carports. Numerous trees were snapped or damaged as well. 

Just north of the neighborhood at a business, a FEMA trailer was completely destroyed with insulation and pieces of the trailer 

strewn northeast and east. On the east side of Hwy. 37, numerous powerpoles were snapped, a semi tractor trailer was 

overturned onto a small pickup, and a home sustained moderate damage to the roof. The tornado continued east-northeast 

crossing FM 1159 and CR 1700. The tornado continued east, north of CR 1700, damaging trees before lifting east of CR 3202. 

The tornado was on the ground for nearly 11 miles and a total of approximately 20 minutes. Maximum winds were estimated 

at 80-90 mph. The maximum width of the tornado was 225 yards wide.

An extended dry period over west Texas, as well as much of the state, resulted in the emergence of Severe (D2) to Extreme 

(D3) drought during the month of March. By the 8th, Severe (D2) drought had developed over portions of the southern Rolling 

Plains. The drought deepened and expanded over the region through the month, and by month's end Severe (D2) drought 

encompassed most of the western South Plains, the Rolling Plains and the extreme southeastern Panhandle, with Extreme (D3) 

drought developing over the southern Rolling Plains (including King and Stonewall Counties) by the 29th. 

Although the drought developed during the region's typical cool and dry season, rainfall for many areas of the South Plains 

region has barely approached one inch between October (2010) and March (2011). These totals amount to two to four inches 

below normal and rank as one of the driest October to March periods on record fro the region. Keetch-Byram Drought Index 

values ranged between 500 and 600 by the end of March. 

Through March, the impact of drought was already evidenced in increased wildfire activity. Impacts on agriculture, the area's 

primary economy, were minimal through March. However, area crops were beginning to show signs of stress as winter wheat 

crops were beginning to suffer. It was evident that if rain did not occur during April, wheat crops would be severely impacted 

and cotton planting would be delayed.

A wildfire ignited in heavy grassland fuels just east of Hale Center (Hale County) around 15:00 CST on the 23rd. Although 

winds were light, breezy and very dry conditions on the 22nd contributed to an enhanced curing of fuels on the 23rd. Relative 

humidity values around 10 percent and temperatures in the 70s helped to promote rapid fire spread in these fuels. The fire 

started when a resident attempted to burn a trash pile along Farm to Market Road 1914. The fire escaped in the parched fuels 

and destroyed two storage sheds when it ran more than 200 acres.

A vintage 1946 Stinson 108 airplane took off from a private airfield near County Road 142 and County Road 129 in Dickens 

County around 04:30 CST on the 27th. The plane, with a pilot and two passengers, encountered low visibility in dense fog

along a fence line, and nose-dived into the ground. The plane burst into flames upon impact, and all on board were killed. 

The above details of the incident were provided as results of a preliminary investigation per the Texas Department of Public 

Safety and the Federal Aviation Administration and were widely reported in local media. Fog and low clouds were widespread 

over the South Plains of west Texas in the wake of a cold frontal passage during the morning hours of the 27th, with officially

The ongoing severe drought, D2, increased to D3, over northern Texas. Much of the state of Texas continued with another 

month of below normal precipitation. In some cases, only a few hundredths were recorded for the entire 31 days. Since 

Thanksgiving, much of northern Texas has seen its driest precipitation totals since the 1920s and 30s. Much of the wheat crop 

planted in the fall had all but been declared a total loss. In fact, the conditions have gotten worse with the emergence of the 

wheat crop. The lack of precipitation has made for low water levels on stock ponds for livestock, and the water level in 

irrigation reservoirs used for crops is falling. Fire weather has been a major concern, with thousands of acres burning 

throughout the month. The exact monetary number for the crop loss can not be determined, although it would probably be in 

the millions.

On March 6th, a slow moving north-south oriented cold front, laden with copious amounts of moisture, entered western 

Vermont by late morning, central Vermont around midday and eastern Vermont by late afternoon. In addition, a surface low in 

the Tennessee Valley tracked along this cold front to the mid-Atlantic states by evening, then the New York City vicinity 

during the early morning hours of March 7th and to the Maine-New Hampshire coast by late morning. 

This surface low and cold front was responsible for severe weather along the Gulf coast states as well as flooding in the 

Tennessee and Ohio River Valleys on March 5th and 6th. 

On March 5th into the morning hours of March 6th, temperatures were in the 40s across Vermont which promoted significant 

snow melt to the region. 

On March 6th, heavy rainfall preceded the cold front as it moved across Vermont. The cold front crept across western Vermont 

during the late morning hours, temperatures fell 12-15 degrees within an hour and heavy rain changed to heavy sleet and then 

wet snow.

The cold front slowed across central Vermont during midday resulting in more rainfall (up to an inch) with a gradual 

changeover to sleet then snow. In eastern Vermont, heavy rainfall (1-2 inches) fell through early to mid-afternoon before colder 

air eventually filtered into the region...reaching the lower Connecticut River valley toward evening, where icing was the main 

hazard. 

At the same time, rapid snow melt and heavy rainfall accounted for ice-covered rivers to swell and cause ice flows. There were 

several reports of ice jams and flooding related problems in the Passumpsic, Missisquoi and Winooski river valleys. 

Heavy snow continued from the afternoon of March 6th to midday on March 7th with the heaviest occurring in the early 

morning hours of the 7th with snowfall rates of 1 to 3 inches per hour. Total snowfall accumulations ranged from 20 to 30 

inches across much of the Champlain Valley and northern 1/3 of Vermont, 10 to 15 inches of snow with ice accumulation up to 

1/4 inch in central Vermont and 2 to 6 inches of snow with 1/4 to 1/2 inch ice accumulation in the lower Connecticut River 

valley.

A substantial rain event in mid January resulted in a strong, thick rain crust on an already established snow pack in the east 

slopes of the Cascades. Mid-January to mid-February was mild with only modest amounts of snowfall added to the slopes. 

Temperatures were much colder through the end of February and a series of storms from February 28th through March 4th 

resulted in heavy snowfall over the thick icy crust. This series of events resulted in an unstable slab of snow susceptible to 

avalanche formation. M28OU

Several rounds of mid and high elevation rainfall impacted Central Washington March 25th through March 27th. Two-day 

rainfall amounts ranged from one to one and a half inches. The combination of the rainfall and a slow snowmelt resulted in 

increasingly saturated soils which eventually became unstable. A large slide which occurred southwest of Peshastin was 

believed to have been caused by the excessive rainfall causing an underground stream to surge out of the steep hillside. This 

stream had surfaced several hours prior to the actual slide according to reports from residents near the 6100 block of Campell

Rain amounts of over an inch were common late on Saturday the 5th. A strong cold front came through during the predawn 

hours of Sunday the 6th. A few hours in the wake of the surface front, the rain changed to wet snow. Snow accumulations 

were highly dependent on elevations. Snow accumulations of 2 to 4 inches were common, except 1 to 3 inches in McDowell 

and Wyoming Counties. The higher terrain around Richwood, Webster Springs, Pickens, and Snowshoe saw 4 to 6 inches of

common. Including this episode, the accumulative affects of 5 significant rain events over the upper Ohio River Valley since 

February 21st, caused the Ohio River to flood. The crest along the Ohio River was mostly 2 to 6 feet above the assigned flood 

stages. The crest occurred late on the 12th into the morning hours of the 13th. Along many reaches, it was the highest stage on 

the Ohio River since 2005. Some of the flood gates were installed in the flood walls at Parkersburg, Point Pleasant, and 

Huntington. 

Many of the flood prone parks and recreational areas along the river were flooded, including some of their outbuildings. 

Several roads were closed, causing motorists to take alternate routes for a few days. 

The unique feature about this flood was the fact that there was no significant headwater river or small stream flooding in West 

Virginia leading to the flooding along the Ohio River.

A lightning fire destroyed a house in the Town of Knowlton. A woman and her dog were home at the time of the fire but were 

able to escape without injury. 

A low pressure system that moved across northern Illinois from Iowa received plenty of moisture from the Gulf of Mexico. 

The abundant Gulf moisture allowed the late-season storm to produce plenty of heavy, wet snow and occasional thundersnow 

across parts of central and northeast Wisconsin on March 22nd-23rd. During the two-day period, many locations received 

more than a foot of snow. Lightning from the storm destroyed a house in Marathon County. 

The high water content of the snow caused more problems than would normally be expected with storms having similar 

snowfall totals. In Marathon County, a squad car was stuck in the snow for three hours on the 23rd, and two plow trucks that 

tried to push it free also became stuck. Plows in Marathon County not only became stuck in the snow, but several broke down 

mechanically attempting to clear the snow from the road. A buildup of hardened snow caused a freight car to derail behind a 

paper mill in Rhinelander (Oneida Co.) on the afternoon of the 23rd. The weight of the snow from this storm caused the roof to 

collapse at a consignment shop on the west side of Green Bay (Brown Co.) on the evening of March 28th. 

Some of the highest snowfall totals from across the area included 18.8 inches at Shawano (Shawano Co.), 18.0 inches at Irma 

(Lincoln Co.), 17.8 inches at Green Bay, 17.0 inches at Peshtigo (Marinette Co.) and Oconto (Oconto Co.), 16.0 inches at

Surface low pressure developed rapidly ahead of a strong short wave trough and moved south of Wisconsin from west central 

Illinois to just south of Chicago. A shield of precipitation spread over southern Wisconsin the night of March 8th with forcing 

from warm air advection ahead of the low, and continued through the morning of the 9th as the low crossed northern Illinois. 

The thermal structure associated with the storm was such that the rain/snow line bisected the Milwaukee/Sullivan County 

Warning Area. Locations along and northwest of a Fond Du Lac to Madison line saw snowfall accumulations of 3 to 5 inches, 

with isolated spots seeing more than 5 inches. To the east of this line, 2 to 4 inches of snow was common. The tier of counties 

right along the Illinois border only received 1 to 2 inches of snow, as most of the precipitation fell as rain.

A powerful storm system developed across the central Plains late Monday evening, and moved northeast across the Midwest 

and slowed down. 

Copious amounts of moisture moved northward across Minnesota and developed a band of heavy rainfall and scattered 

thunderstorms the morning of Tuesday March 22nd. Some of the rainfall began to mixed with sleet by the afternoon across 

portions of west central Wisconsin. The mixture of sleet, snow and patches of freezing rain, switched over to all snow by 

Tuesday evening, and became heavy at times during the night. 

Portions of west central Wisconsin, from Osceola to Menomonie, Chippewa Falls, and Ladysmith, received locally 6 to 11

Storm Data Disclosure 

Storm Data is an official publication of the National Oceanic and Atmospheric Administration (NOAA) which 

documents the occurrence of storms and other significant weather phenomena having sufficient intensity to cause loss 

of life, injuries, significant property damage, and/or disruption to commerce. In addition, it is a partial record of other 

significant meteorological events, such as record maximum or minimum temperatures or precipitation that occurs in 

connection with another event. 

Some of the information appearing in Storm Data may have been provided by or gathered from sources outside the 

National Weather Service (NWS), such as the media, law enforcement and/or other government agencies, private 

companies, individuals, etc. An effort is made to use the best available information, but because of time and resource 

constraints, information from these sources may be unverified by the NWS. Therefore, when using information from 

Storm Data, customers should be cautious as the NWS does not guarantee the accuracy or validity of the information. 

Further, when it is apparent information appearing in Storm Data originated from a source outside the National 

Weather Service (frequently credit is provided), Storm Data customers requiring additional information should contact 

that source directly. In most cases, NWS employees will not have the knowledge to respond to such requests. In 

cases of legal proceedings, under Department of Commerce regulations and/or rules of the court, NWS employees are

An “Episode” is an entire storm system and can contain many different types of events. 

An “Event” is an individual type of storm event. 

When listing wind speed values under “Character of Storm”, i.e. High Wind (G81): The G indicates a “Gust” which is 

a peak 5-second averaged wind speed in Knots (kts). 1 kt. = 1.152 mph. This number can be either E (estimated) by 

damage caused, or M (measured) by known calibrated anemometers. Examples: (M61) = measured 61 knots; (E75) = 

estimated at 75 knots. 

All wind speeds listed are estimated by NWS personnel by the amount and type of damage unless otherwise noted 

with an “M” which represents an actual wind speed as measured by official NWS approved anemometer. 

When listing hail size under “Character of Storm”, ex. Hail (2.25), the hail size is given in inches and hundredths of 

inches. 

When listing property and crop damage, the figures indicated are the best guess made by the NWS from the available 

sources of information at the time of the printing. 

The fatalities, injuries, and damage amounts appearing in tropical cyclone events are attributed only to wind damage 

experienced in the coastal counties/parishes listed. Other tropical cyclone related events such as tornadoes and 

flooding are listed within their separate event types.

The Saffir-Simpson Scale 

Category One Hurricane: 

Winds 74-95 mph (64-82 kts or 119-153 kph). Storm surge generally 4-5 ft above normal. No real damage to 

building structures. Damage primarily to unanchored mobile homes, shrubbery, and trees. Some damage to poorly 

constructed signs. Also, some coastal road flooding and minor pier damage. 

Category Two Hurricane: 

Winds 96-110 mph (83-95 kts or 154-177 kph). Storm surge generally 6-8 feet above normal. Some roofing material, 

door, and window damage of buildings. Considerable damage to shrubbery and trees with some trees blown down. 

Considerable damage to mobile homes, poorly constructed signs, and piers. Coastal and low-lying escape routes flood 

2-4 hours before arrival of the hurricane center. Small craft in unprotected anchorages break moorings. 

Category Three Hurricane: 

Winds 111-130 mph (96-113 kts or 178-209 kph). Storm surge generally 9-12 ft above normal. Some structural 

damage to small residences and utility buildings with a minor amount of curtainwall failures. Damage to shrubbery 

and trees with foliage blown off trees and large trees blown down. Mobile homes and poorly constructed signs are 

destroyed. Low-lying escape routes are cut by rising water 3-5 hours before arrival of the hurricane center. Flooding 

near the coast destroys smaller structures with larger structures damaged by battering of floating debris. Terrain 

continuously lower than 5 ft above mean sea level may be flooded inland 8 miles (13 km) or more. Evacuation of 

low-lying residences with several blocks of the shoreline may be required. 

Category Four Hurricane: 

Winds 131-155 mph (114-135 kts or 210-249 kph). Storm surge generally 13-18 ft above normal. More extensive 

curtainwall failures with some complete roof structure failures on small residences. Shrubs, trees, and all signs are 

blown down. Complete destruction of mobile homes. Extensive damage to doors and windows. Low-lying escape 

routes may be cut by rising water 3-5 hours before arrival of the hurricane center. Major damage to lower floors of 

structures near the shore. Terrain lower than 10 ft above sea level may be flooded requiring massive evacuation of 

residential areas as far inland as 6 miles (10 km). 

Category Five Hurricane: 

Winds greater than 155 mph (135 kts or 249 kph). Storm surge generally greater than 18 ft above normal. Complete 

roof failure on many residences and industrial buildings. Some complete building failures with small utility buildings 

blown over or away. All shrubs, trees, and signs blown down. Complete destruction of mobile homes. Severe and 

extensive window and door damage. Low-lying escape routes are cut by rising water 3-5 hours before arrival of the 

hurricane center. Major damage to lower floors of all structures located less than 15 ft above sea level and within 500 

yards of the shoreline. Massive evacuation of residential areas on low ground within 5-10 miles (8-16 km) of the 

shoreline may be required.

EF-Scale Intensity Wind Speed 

(mph) 

The Enhanced Fujita Scale 

Typical Damage (Suggested) 

EF0 Gale Tornado 40 - 72 Tree branches broken, chimneys damaged, shallow-rooted 

trees pushed over; sign boards damaged or destroyed, 

outbuildings and sheds destroyed. 

EF1 Moderate 73 - 112 Roof surfaces peeled off, mobile homes pushed off 

foundations or overturned, moving autos pushed off the 

roads, garages may be destroyed. 

EF2 Significant 113 - 157 Roofs blown off frame houses; mobile homes demolished 

and/or destroyed, train boxcars pushed over; large trees 

snapped or uprooted; airborne debris can cause damage. 

EF3 Severe 158 - 206 Roofs and walls torn off well constructed houses; trains 

overturned; large trees uprooted, can knock down entire 

forest of trees. 

EF4 Devastating 207 - 260 Well-constructed frame houses leveled; structures with weak 

foundations blown off some distance; automobiles thrown, 

large airborne objects can cause significant damage. 

EF5 Incredible 261 - 318 Brick, stone and cinder-block buildings destroyed, most 

debris is carried away by tornadic winds, large and heavy 

objects can be hurled in excess of 100 meters, trees 

debarked, asphalt peeled off of roads, steel reinforced 

concrete structures badly damaged. 

EF6 Inconceivable 319 - 379 Brick, stone and cinderblock buildings destroyed, most 

debris is carried away by tornadic winds, large and heavy 

objects can be hurled in excess of 100 meters, trees 

debarked, asphalt peeled off of roads, steel reinforced 

concrete structures badly damaged. 

Typical EF0 Tornado Damage 

Note the trees are stripped of leaves, but the 

trees remain standing. Only light roof 

damage and a few missing shingles. 


Note the uprooted trees and missing shingles 

from the roof. There is significant roof 

damage.


This home is missing it’s entire roof but the 

exterior walls remain intact. Some of the 

stronger hardwood trees remain standing. 


This home is missing the entire roof as well as 

some of the exterior walls. Trees are blown 

over or snapped near the base and 

outbuildings are destroyed. 


This home is almost completely obliterated, 

with no walls standing. The debris from the 

home is where the house once stood. 


These homes have been completely removed 

from their original locations. The debris 

field has been scattered some distance from 

their foundation. 


The asphalt surface has been peeled off of 

this road.
