A fast moving clipper system moved through on the 6th.  It was aided by a wind speed maximum in the flow aloft.  Surface temperatures were only in the upper teens to lower 20s.
Four to 6 inches of dry snow accumulated in 12 to 15 hours over a portion of the lowland counties in West Virginia.  This was mainly along the Route 50 corridor.  In the more mountainous counties of Barbour, Upshur, and Randolph, snow accumulations of 6 to 8 inches were common.  The maximum snow accumulation reported was near 10 inches from Alpena.  The water content of the snow was mostly 0.25 to 0.40 inches.
This was the first accumulating snow storm of the winter for the northern lowland counties. Further south in West Virginia, the snow amounts were much less, diminishing to zero in the Huntington to Charleston corridor.
The higher snow criteria in north central West Virginia for heavy snow, compared to the mid Ohio Valley, was the determining factor for 2 different event categories in this episode, despite rather similar accumulations.
