I can not remember a tougher snow accumulation forecast off-hand. The entire atmosphere across much of the region is sub-freezing until you get down to the surface and just above. Because of that above freezing air near the ground, it will take some heavier rates of precip to get the precip to be snow and not rain, at least initially.
As of now, I am not making any huge changes to my going forecast, but I have changed the orientation of the accumulation areas a bit. For the Triad, Charlotte and into the foothills, I will go with 2-4" with some locally higher amounts, mainly northwest of I-85.
Around RDU, especially just east of there, right up through northeastern NC I have another area of 2-4". From Atlanta to Columbia along I-40 and points north I have 2-4" as well. Most other areas are in the dusting to 2" category.
There will likely be a strip that sees in excess of 4 or even 5 inches, but where that sets up is still very tricky. Other areas that do not get the heavier rates of precip will have a tough time seeing accumulations at all. See the video for details.
It will be cold and breezy tomorrow, and temps remain in the 40s for highs through Friday. Warmer weather rolls in this weekend and early next week.
