Another round of wintry weather is on the way to North Carolina late Sunday night and Monday.
Snow showers hits western counties in the late morning, with the storm spreading more widely during the afternoon.
The greatest chance for significant snowfall accumulations will be well west and northwest of the I-95 corridor in the Northeast, from the Appalachians to western Pennsylvania, western, central and Upstate New York and northern New England.
Snow will begin late Sunday night and continue through Monday before changing to sleet and freezing rain on Monday. “Ice accumulation of a 1/2” or more is possible.
“This area [with amounts in excess of six inches] will feature highly-impactful travel disruptions via snow-covered and slippery roads”. After midnight, precipitation is expected to switch over to rain.
Looking ahead to early next week, a stronger winter storm system is expected to move into the region late Sunday through Monday night.
In the South, the heaviest snow accumulation may occur in a swath from Kentucky to Tennessee and the Appalachians, where some totals could approach or locally top 6 inches. The precipitation should change to rain Monday evening.
Warmer air begins moving in out of the south, turning our snow to a wintry mix of precipitation, with sleet and freezing rain possible overnight into early Tuesday. Travel could remain treacherous into the morning hours. Temperatures should warm above freezing by mid afternoon.
Periods of moderate snow will continue through Monday morning and into the early afternoon. “Near the Raleigh and Durham area snow and sleet accumulations should range from a trace to less than 1”.

Plain rain with temps above freezing in the metro and southeast Virginia. The freezing rain will add some ice accumulation on top of the snowfall, but as temperatures warm up and the precipitation changes to all rain, the snow and ice will all melt.
