Accumulating snowfall is expected for the lee of the central Rockies and the central High Plains through Thursday, the southern Appalachians and across much of North Carolina, northern South Carolina and southern Virginia late Thursday into early Friday. Locally several inches of snow is expected.
The snow could come at the worst possible time Thursday for North Carolina, as 1 to 2 inches of snow is possible during the evening commute.
Light accumulations are forecast from parts of Tennessee to portions of North Carolina and southern Virginia.
Snow is expected from Colorado to Kansas, where locally a half foot of snow is possible, and 6 to 8 inches of snow from the Great Lakes to New England.
Unfortunately, with ongoing major to historic river flooding, another round of precipitation is expected to push eastward from the southern Plains tonight and move east across the Gulf Coast states and Southeast on Thursday. Additional moderate to heavy rainfall is expected across these areas, exacerbating the ongoing significant river flooding across areas of the South.
By Thursday morning, an additional 1 to 3 inches of rain will move into already flooded areas of the South from Mississippi to Alabama.
Meanwhile, Arctic high pressure pushing down across the north-central U.S. today will spread east-southeastward and encompass much of the central to eastern U.S. going through Thursday, keeping temperatures below average for this part of the country.
Wind chills could dip as low as 30 degrees below zero in the Upper Midwest and the Western Great Lakes.
