Snow update with accumulation forecast...

As I mentioned earlier, the model data has reached a pretty good consensus regarding the winter storm to affect us tomorrow night and Friday. Despite today's nice weather, an arctic front will cross the region tonight, plunging temperatures into the 20s by morning. Cold, dry air will continue to ooze into the area tomorrow. Meanwhile, low pressure will track through the Gulf states and then redevelop along the North Carolina coast. Moisture will begin to overspread the region later tomorrow, but with cold, dry air in place, it will take some time for snow to develop. It should begin in the metro sometime during the evening. The time to watch for the most significant snow will be Saturday morning into early afternoon. The track of the storm will be critical to snow amounts, as a sharp contrast will likely be present across the Commonwealth from very light accumulations near DC to a heavy snowfall in southern Virginia to the North Carolina line.

Based on the current data, here are my current thoughts:

Metro Richmond: 5-9 inches (highest across the southern half/Chesterfield County)
Tri-Cities south to NC: 9 inches + (locally a foot or more possible...assuming sleet doesn't mix in)
Charlottesville: 4-7 inches
Fredericksburg: 3-5 inches

Stay tuned for updates...
