That’s like 18+ hours of snow for NE NC.

From what I can try to tell, there seems to be snow in Chattanooga now. Can anyone there confirm? Also the CC line is nearing Dalton now.

nearest wx station near my office off Mansell was showing 39 down here a while ago. NE wind was howling. Not expecting anything, but I was surprised.

The changeover in the Upstate is at the Gaffney, Boiling Springs, TR area which is way ahead of schedule for the NAM. 850's are solidly below freezing in the northern upstate and 925's are right at freezing so this is a very good sign in my opinion.

I see some spotty sleet reports in northern upstate but that's all
 
Latest HRRR has 7-8" down IMBY at hr 18 and still snowing decent with several more hrs to go....starting to think 6-10" is doable would be the biggest snow here in a solid 10 years if we get 8" or more....still would feel better if the temps would crash a bit lol....still the 925/850's are going to be plenty cold once we get the heavier banding setting up it should go all snow fast and surface temps will crash.

Perhaps part of the problem for the NW Piedmont is the angle of approach. The precipitation is coming primarily from the west—over the mts and into relatively dry air. If the overall system were not so flat and the returns were approaching from the SW, then things would be different.

Good luck to everyone from RDU east. I hope you get a good one.

I definitely agree here .. I think the faster you get saturated the easier it is to get more returns and more precip in any one area
 
Something to point out on the latest NAM runs .. they don’t have as much precip in Tennessee as there actually is .. returns are back building and are easily up to the Kentucky Tennessee border and the NAMS have precip no where further than the middle of Tennessee

CAD is actually to blame for bringing dry north-East winds with low dp. Usually it’s confined to Surry/Wilkes but I think the issue became more widespread when you start to compound transfer issues it’s like a double whammy for the entire Triad region west. Those stale cold dry winds will work to eat away some precip but maybe not all.
