|A cold high pressure system arriving from the north, coinciding with the approach of a mid and upper level trough from the west allowed for winter weather to develop over central North Carolina. As precipitation developed during the day on February 20, colder air continued to be advected into North Carolina courtesy of strong high pressure located over the Great Lakes. A brief mixture of rain and snow changed to snow as the precipitation spread east throughout central NC during the late afternoon and early evening. Temperatures were near or slightly above freezing during the late afternoon, limiting accumulations. Temperatures fell below freezing during the evening and the snow accumulated rapidly. By late evening, light snow was falling over much of central North Carolina. The snow ended shortly after midnight at most locations. Storm total snowfall amounts ranged between one and four inches, with most Triad and Triangle locations receiving between two and three inches.
Moisture overspreading a southward-moving cold front resulted in development of precipitation across the North Carolina mountains throughout the daylight hours of the 21st. Temperatures were cold enough in most locations for this precipitation to fall as snow, although rain mixed in at times below about 2500 feet. By the time the snow tapered off during the evening, snowfall totals ranged from trace amounts up to an inch in the lower interior valleys, to 1 to 4 inches above 2500 feet and in the valleys near the Blue Ridge.
