A low pressure system moved out of the central Plains into the Ohio Valley, opening the Mid-Atlantic to southwesterly flow that was enriched with moisture. Along with the increasing moisture was rising temperatures, meaning precipitation types changed through the event as temperatures climbed. In the end, parts of North Carolina received a mix of snow, sleet, and freezing rain.
