It appears the tornado began at 614 AM CDT. There was F0 damage, in the form of scattered treedamage, from Vine Road just south of the Clay County line, east to near Highway 49. The damage increased to F1 damage alongHighway 49, especially to the southeast of the highway. There were several dozen trees snapped and uprooted, with many signs ofconvergence in the pattern of fallen trees. There were a few broken windows in two houses, and one house had its carport lifted upoff most of its support columns.

There was no roof on this building and it was taller than the two adjacent andattached buildings.
