Looks to me like the front edge of the heavier precip is bumping up against 77 now and brings a temp drop of about 3 degrees. So I look for flakage at 36-37 degrees around noon today across Winston Salem and into GSO. The question is how far east it gets before the moisture finally outruns the cold and how much backfill we see across the foothills.

Light rain has started back in the piedmont even noticing on radar a slight NW pull with the moisture. Really the clouds look like snow but the temps aloft have to drop some more and thickness indicates temps dropping. 

 

But still expect the radar to fill in some along this 700-850 frontal max.

If all of that moisture down around clt and spartanburg pivots right now we could be looking at 90 minutes of snow across the triad. Some places heavy where the changeover occurs quickly. We just need that moisture to wrap up and move NNE or else this will simply be a passing snow shower. Either way, totally cool!

Well looking at a combo of Greer and Blackburg precip shield is building over western NC so thats a good thing. Really as this trough axis moves further away from the mountain influence it should be even build more in the NC piedmont. So timing wise would be from Noon to later this evening.

 

If the rap is right in a sense about building the 700mb rh field and precip shiled... some places in the NC piedmont could get the ground covered in a sloppy inch or so.
