An area of low pressure progressed from the Tennessee Valley to the east coast, and then farther northeast to off the New England Coast. The impact on the region was first widespread rain. As colder air moved into the region once the area was on the western side of the low, there was a transition from rain to snow, with a brief period of freezing rain and sleet. Snowfall totals from the event ranged from 4 to 5 inches within the region of roughly Roanoke to Lexington to just north of Lynchburg, VA. Farther west across the mountains, amounts were more in the 5 to 10 inch range across parts of the New River Valley, and 6 to 12 inch range across the southern Alleghany Highlands.
