Synoptic Patterns Associated with <strong>the</strong> Record <strong>Snow</strong>fall<br />

Record snowfall totals of up to 211 cm bl<strong>an</strong>keted <strong>the</strong> Sou<strong>the</strong>rn Appalachi<strong>an</strong>s between mid-<br />
February <strong>an</strong>d late-March 1960. <strong>Snow</strong> w<strong>as</strong> reported on average every o<strong>the</strong>r day in <strong>the</strong> higher<br />
elevations, <strong>an</strong>d me<strong>an</strong> temperatures for <strong>the</strong> period were nearly 6 C below normal. <strong>Snow</strong> piled up to<br />
great depths, with Boone, NC, reporting a maximum depth of 112 cm. <strong>Snow</strong> drifts buried roads<br />
<strong>an</strong>d made travel impossible, requiring food, fuel, <strong>an</strong>d hay to be airlifted into <strong>the</strong> region. This paper<br />
<strong>an</strong>alyzes <strong>the</strong> synoptic patterns <strong>as</strong>sociated with <strong>the</strong> record snowfall of February <strong>an</strong>d March 1960.<br />
<strong>Snow</strong>fall events are identified using a combination of first order hourly observations <strong>an</strong>d<br />
cooperative observer daily snowfall totals. The spatial patterns of snowfall are mapped using a<br />
GIS, while me<strong>an</strong> values for various synoptic fields (e.g. 850 hPa temperature, 500 hPa height) are<br />
calculated <strong>an</strong>d compared to 50-year climatological me<strong>an</strong>s. <strong>Snow</strong>fall events during this period are<br />
<strong>the</strong>n cl<strong>as</strong>sified according to <strong>the</strong> pattern of cyclogenesis <strong>an</strong>d prevailing flow direction.<br />

INTRODUCTION<br />
February <strong>an</strong>d March 1960 continue to be remembered <strong>as</strong> <strong>the</strong> snowiest period on record in <strong>the</strong><br />
Sou<strong>the</strong>rn Appalachi<strong>an</strong>s. <strong>Snow</strong> w<strong>as</strong> nearly a daily occurrence between 13 February <strong>an</strong>d 26 March<br />
at higher elevations, with Boone, NC, reporting 211 cm <strong>an</strong>d m<strong>an</strong>y o<strong>the</strong>r locations in excess of 175<br />
cm. These snowfall totals are considerably greater th<strong>an</strong> <strong>the</strong> current 30-year me<strong>an</strong> <strong>an</strong>nual snowfall<br />
of 102 cm for Boone <strong>an</strong>d approach <strong>the</strong> me<strong>an</strong> <strong>an</strong>nual values of nearly 250 cm for <strong>the</strong> 2,000 m peaks<br />
(e.g Mt. Leconte <strong>an</strong>d Mt. Mitchell) of <strong>the</strong> Sou<strong>the</strong>rn Appalachi<strong>an</strong>s. Me<strong>an</strong> temperatures for <strong>the</strong><br />
period were nearly 6 ºC below normal (Hardie 1960). The combination of frequent snowfall <strong>an</strong>d<br />
low temperatures allowed <strong>the</strong> snow to pile up to great depths, with Boone, NC, reporting a<br />
maximum depth of 112 cm on 13–14 March (NCDC 2002). Considerable blowing <strong>an</strong>d drifting of<br />
snow compounded problems, closing roads <strong>an</strong>d requiring emergency distribution of food, fuel, <strong>an</strong>d<br />
hay (Figs. 1 & 2). Although <strong>the</strong> impacts were greatest in <strong>the</strong> Sou<strong>the</strong>rn Appalachi<strong>an</strong>s, <strong>the</strong> <strong>entire</strong><br />
E<strong>as</strong>tern U.S. w<strong>as</strong> adversely affected. March alone broke more records for cold <strong>an</strong>d snow across <strong>the</strong><br />
E<strong>as</strong>tern U.S. th<strong>an</strong> <strong>an</strong>y o<strong>the</strong>r March on record until <strong>the</strong>n (Ludlum 1960a, Ludlum 1960b). It<br />
remains <strong>the</strong> coldest March on record for m<strong>an</strong>y locations in <strong>the</strong> Sou<strong>the</strong>rn Appalachi<strong>an</strong>s (NCDC<br />
