SNEAKY SNOW COME AND GO - THEN THE REAL DEAL?

Good morning N.C. Piedmont. Hope you like early AM snow. Might be some excited kids out there.




WWA's (Winter Wx Advisory) posted by NWS GSP for all of the NC Piedmont forecast area (Davie, Rowan, etc) for a quick disturbance moving through in a few hours that could leave anywhere from a dusting to an inch, perhaps 2" if you are closer to CLT or the foothills.

Wouldn't be surprised to see schools cancel b/c timing of what are really just some light snow showers - however will be around sunrise / bus time. Ground temps are cold so if it falls it should stick. If you thought Tuesday was gonna be warm - grab an extra coat.

Most snow should be out of here by mid-morning, if you get much at all. Interesting little system because it has come on strong late...most won't be expecting this I would imagine. Weather guessers were not but you know what they say about that job. NWS WWA out late in the period as stated below. NWS in Raleigh has yet to issue anything but likely they will do the same.


SO, the real news is the snow-storm Wednesday across much of NC. Talking 4+" most places (better if you live near Raleigh/Coast...) Could be higher bust potential in our area because there should be a cut-off zone where it snows/precips less as gulf moisture transports to Atlantic low. Hopefully not us but we usually see such an area in the synoptic setup. Not sure if that is CYA Penn talking. 
Busts hurt people. 
They hurt. 

Graphic (1) from WPC about snow threat (almost 12 hrs old now) and (2) latest high res NAM model run showing general idea / track of storm coming in Wed and headed out by Thursday.







Any-who, will fine tune those thoughts later today (hopefully) if I have time. But Wed PM - Thurs AM time frame is the target. Enjoy any and all snow you get today. And your kids home again too if schools CYA out too. Be safe. NWS Advisory text follows after break. Out.
