MORRISTOWN — The National Weather Service has issued a winter storm warning for heavy snow, which is in effect from 3 p.m. Thursday to 7 a.m. Friday.
Snow accumulations of 3 to 6 inches are possible, with up to 8 inches across the highest elevations.
Forecasters say an area of low pressure will move into the southern Appalachians Thursday, producing light rain, which will turn into snow late that afternoon as an Arctic cold front moves across the region.
Officials say a significant snowfall is possible late Thursday and Thursday night, with moderate to heavy snow accumulations across the mountains of Southwest Virginia and far East Tennessee. Light snow accumulations are possible across the northern Cumberland Plateau and lower elevations of Southwest Virginia.
In addition to the snow, very cold air and blustery northwest winds are expected Thursday night. Temperatures will fall into the teens and lower 20s, and highs Friday will be only in the 20s and lower 30s. Wind chill values Friday morning will fall to between -5 and -10 degrees in the mountains.
Roads may become covered with snow and ice late Thursday and Thursday night, especially roadways at or above 2,500 feet.
