The December 16th, 2010 Wintry Mix Event

Low pressure moved from the Southern Plains late Wednesday, December 15th into south-central Kentucky Thursday morning Dec 16th. Weak high pressure resided over the area early with an arctic airmass in place. Precipitation moved northeast out of Tennessee into the area during the early morning Thursday. Most of the precipitation made it into areas along and west of the Blue Ridge around dawn Thursday, spreading quickly east by mid morning. Warmer air above the sub-freezing surface entered the mountains of far southwest Virginia into North Carolina quicker than forecast models projected, changing the snow to sleet/freezing rain. Highest precipitation amounts were observed across the I-81 corridor from Smyth Co to the the New River Valley. The surface low lingered across southern Kentucky through midday pushing into southwest Virginia by the afternoon. As this occurred, the switchover to sleet/freezing rain advanced further north into the New River Valley and Roanoke valley. This cut down on snow totals. The main snow band stayed across the Greenbrier Valley of Southeast West Virginia east to the southern Shenandoah Valley. From portions of far southwest Virginia from Tazewell and Richlands, south to Marion, west toward Tennessee, more ice was observered before temperatures warmed above freezing by early afternoon. Another area along the Blue Ridge from Watauga and Ashe County northeast to Meadows of Dan, and points to the east also received a little more ice before changing over to rain by the afternoon. See the maps below for analysis of the snow, sleet and freezing rain.

Thanks to everyone who provided snowfall reports for this event, including spotters, volunteer observers, highway departments and others.
