I know it's the NAM, but I just have a feeling it has the right idea. The cold air is going to have a very hard time crossing the mountains I'm afraid. You are set though if you are in Asheville, Hickory, the Triad in NC and on up into VA. Those areas get 4-8 inches of snow. Basically if you got snow just before Christmas in Dec 2009 you'll get snow tonight. If you got rain then, you'll get rain tonight.
