So unless it turns to all rain then Brad P and the models showing raining for the first several hours will bust and could see a little sleet accum and maybe faster transition to snow mix.

The last several runs of the HRRR on weathernerds.org are significantly speeding up the changeover to snow in Charlotte-Fayetteville. Might be headed to Fayetteville for this after all. Need a few more runs to be 100% sure.
Sitting at 39 at canton Georgia with a dew point at 37 with a northeast wind. Man it’s gonna be close?
Headed to highlands NC

HRRR on weathernerds has the column crashing within the next hour for the upstate so be patient.
Pretty close to our high for today, 43.7/33.8, with a light NNE wind. That will verify about 4 degrees lower than the most recent HRRR run and in line with the NAM. Somewhat concerned we don't mix out the last couple thousand feet later today and tonight, melting is a self limiting process but CAA never really gets going at the surface until the tail end.
Few pingers here, just started, mixed with -RN.

Latest HRRR is stuck on Hr 3 but it looks like it could be showing a change over faster (maybe).
RDU dew point down to 27!!!

Even where the radar says a mix, the soundings show snow which is really good to see.

sleet mixing in here already as well, once good rates develop I suspect it will be more IP/SN than rain even with surface temps in the mid to upper 30's, if we an get those to crash then this overperforms I think....
hrrr on weathernerds really crashes that column quick across much of NC

I guess it's coming even faster than thought. The CAD is breaking the 925 down to freezing as we speak across N GA, so that layer is almost done. 850s crashing almost vertically it appears in N GA.

I think it may take a little longer to change over to snow for area, but it also looks like the precipitation will hang around longer into the night than previously forecasted.
The 10z HRRR showed the dewpoint above freezing for RDU for 15z. It was about 5-7°F too warm.
I saw an MPing just north of the TN border reporting snow about 30 minutes ago. The traffic cameras in Huntsville show it is coming down good there too.
