This is an odd event coming in, odd because we may not drop to 32 degrees until Wednesday night. Instead of coming in from the NW, a low off the Carolina coast will spin moisture up from the coast and pull down some colder air aloft, and the ruling thought is we'll accumulate a few inches of wet snow. There may be no accumulation for places near us to the north....Maggie's zone forecast calls for no accumulation overnight.
A Winter Weather Advisory is in effect from 9pm tonight through 12 noon Wednesday. 2-4" of wet snow is expected in the advisory counties, especially to the south.
My models have both had ACA in a 3-5" zone, but I expect some melting if not rain mixing in as our forecast low is only 33 degrees. The latest run of the NAM has us in 10-12", so maybe it is seeing potentially colder temps and more snow/less rain. The GFS has not yet followed suit. Ugh. Given our warm ground temps, I really don't expect travel troubles in ACA unless you have only 2WD which might be problematic in thicker slush should it amount to that on our roads. The 2-4" outlook for the moment seems plausible.
Snow chances, albeit limited, will return Wednesday night and parts of Thanksgiving Day when temperatures will be colder, just less moisture to work with.
