Most local mets don't have anything over 2inches. All claiming the ground is too warm. WTKR, WVEC all under 1in everywhere with WAVY at 1-2 for Norfolk westward. It seems like everyone is taking a conservative approach as usual for this one

 

A LOT of snow will fall at times late Saturday and Saturday night. The big question is how much will stick with the warm ground and air temperatures that will be well above freezing. If you were to put out a frozen plate you would end up with several inches on it, but 60 degrees for highs Friday should mean much less sticking on the ground.-Jeff Lawson

I've got to stay conservative with this one and a general 1" with 2"-3" in some spots I think is going to about do it here. The ground is really warm and it seems like the models are kicking the precip off a little earlier which is going to mean more of a mix to start so that will cut back on accums. as well. Hey it's 1"-3" more than I thought I was going to get a couple of days ago so I'll take it.

Don't count your chickens before the eggs hatch.  My guess is generally a dusting to an inch.

Keeping a close eye on the vort coming through Kansas now. It dropped a quick couple of inches there. This is the feature that helps the Upstate/lower NC around midday tomorrow for snow chances there. However, temps just off the ground are warm in the lee of the Southern Apps and this has happened, many, many, many times for extreme western SC, southern foothills NC , northeast GA region where even though its plenty cold enough aloft to snow, the bubble of warmth near the ground turns it to rain. However, this vort is pretty powerful and may offset that low level warmth. Tough call. Further east the snow chances are better with better rates, more moisture and actually colder temps at 950 to 925 mb layer. So still, my favorite spot for significant snow (falling and the rates) is the Raleigh, Fayetteville, Rocky Mt and Norfolk region.
The NAM continues to trudge a little more moisture west with each run. The key now is the actual obs upstream (radar, satellite, ground reports).
