Areas along the border of Virginia and West Virginia could pick up 2-5 inches of snow with locally higher amounts. Further south, sleet will be more prevalent with widespread accumulations of 1-2 inches. Across the higher elevations, snow accumulations will range 4-6 inches with locally higher amounts in excess of 8 inches.

Snow will taper off from south to north, ending completely by late Friday night.

Thunderstorms Thursday for the Carolina Coast
A large upper level low is situated over the Midwest this morning. To the east and southeast of this low, numerous showers and thunderstorms are ongoing from Florida into the Northeast. Strong to severe thunderstorms may develop along the Carolina coast where plentiful moisture and instability are present. A broken line of thunderstorms is forecast to develop along the coastal regions and quickly move eastward through the late morning. This will pose a threat for damaging winds and perhaps a couple of tornadoes as storms move offshore by the afternoon.
