Wider weather episode

Moist air flowing over a wedge of cold air banked against the eastern slopes of the Appalachians resulted in precipitation development across the foothills and northern Piedmont during the evening of the 12th, continuing through the overnight and early morning hours of the 13th. The atmosphere quickly cooled to around freezing north of I-85, resulting in some freezing rain in these areas. By the time the precipitation ended around sunrise, ice accretion of up to a tenth of an inch was reported across this area, mainly on elevated surfaces.
