Snow developed during the day on Tuesday the 11th.  This was in response to a weak low pressure tracking east across the upper Ohio River Valley.  The snow intensity increased during the late evening hours of the 11th, then transitioned into snow showers during the overnight.  The snow showers became drier and fluffier as colder air blew in during the early morning hours of the 12th.  The snow showers decreased in coverage and intensity by dawn on the 13th.
Increases in snow depth of a foot were common across Upshur, Randolph, Webster, and western Pocahontas Counties.  The snow depth increased 6 to 10 inches across Barbour, Nicholas, Fayette, Raleigh, Wyoming, and McDowell Counties.  For example, some preliminary data indicated the snow depth in the town of Buckhannon went from 3 inches to 15 inches.  On the mountaintop near Richwood, the snow depth increased from 5 inches to 21 inches. The snow depth at Pickens increased from 10 inches prior to this event to 24 inches.  A few other increases in snow depth included Beckley from 4 inches to 9 inches, Elkins from 5 inches to 12 inches, Oak Hill from 2 inches to 9 inches, Belington from 3 inches to 10 inches, Oceana from zero to 8 inches, and finally Mt Nebo from 4 inches to 16 inches.
Lesser amounts of snow fell across the western lowland counties.  Snow accumulations of 4 to 6 inches were common across Calhoun, Roane, Jackson, Braxton, Gilmer, Lewis, Harrison, and Taylor Counties.  However, some narrow banding of the snow showers occurred during the evening hours of the 12th, causing localized deeper snow accumulations.
