I agree that temps would be an issue, but I think it's possible (although perhaps unlikely) that rates would win out. Temps fall to just below freezing in the heaviest bands in Greensboro. I could see Raleigh falling into the 33-34 range given heavy enough precip, if that band can manage to hold together past the Triad
It's a long shot, but my main point is that it's a small step in the right direction for those of us in the Piedmont, towards some fun nowcasting
