Other neighboring National Weather Service offices in Greenville-Spartanburg, Wilmington and Raleigh have also issued Winter Weather Advisories as well for portions of their coverage area.
A cold front has crossed the region early this morning. Temperatures will rise a few degrees to near 40 degrees. An upper level disturbance will increase precipitation across the area today. Precipitation will start late this morning in the form of rain, but mix and change to snow by early to mid-afternoon.
As colder air continues to build into the area, there could be a burst of moderate to heavy precipitation. Heavier precipitation would lean more toward snow and accumulations could begin to accumulate on grassy areas, despite warm ground temperatures. Surface temperatures will slowly fall from near 40 into the mid 30s later in the afternoon. At this time, there is no concern for accumulation on roads because of above freezing surface temperatures. However, bridges and overpasses are always colder and slippery conditions could develop.
The precipitation will move out of the area in the evening. Overnight low temperatures will fall into the lower to mid 20s. Black ice is pretty much a guarantee at this point from below freezing temperatures and wet roads.
Snow accumulation could differ location to location. On average I think snow amounts will range from 1 to 2 inches. Around an inch for Metro Columbia, lesser amounts towards Augusta and Orangeburg, higher amounts towards Winnsboro. It's not out of the the realm of possibility that isolated amounts of 3 inches could occur, especially across the Northern Midlands and into portions of the Pee Dee region.
