surprise?
There are currently flurries in chapel hill with an air temp of 34 F. There were reports of coatings of snow just to the south (pittsboro). The raleigh NWS is now issuing "less than one inch" amount immediately northeast of raleigh. I bet that northeast NC and SE Va will see at most 2 inches. The upper air support for this snow is moving off to the northeast and there are very clear ENE banding features on the radar, consistent with the lower level flow. Also, east of Raleigh, the temp profile looks marginal at best for snow, with sleet and rain more likely. Interesting event.
