Meanwhile, colder air north of the storm track is forecast to bring wet snow, sleet and/or freezing rain for portions of the southern and central Appalachians tonight and into Sunday.
Given the dynamic nature of this system and the marginally cold airmass in place, accumulating snowfall may be limited to the upslope regions of the Appalachian Mountains, where there is a 50-80% chance of snow accumulating 4"+.
In addition to the snow, warm air aloft will bring a risk of icing over portions of the interior Mid-Atlantic, particularly over the central and southern Appalachian Mountains.
WPC has issued a 30-50% probability of 0.1" of ice accretion over northwestern North Carolina and into southwestern Virginia.
