Are you in or NW of the snow line?

indeed it is, -1°C line not too far behind to our west. I wish temps at 925mb were dropping just as fast. Were between 3-4°C which I don't think is horrendous, that would probably be or at least close to a sleet sounding if evaporational cooling was in effect right now.
 
I have to say I wish I were on the north side of ATL right now, especially Cobb County. According to all of the 18Z GFS, 12Z Euro, and 12Z CMC, Cobb and nearby areas will have mainly SN falling (starting as a mix with rain) for ~18 straight from just before or near sunrise Fri til midnight Fri night. Qpf during that period is 0.5"-1" with the GFS wettest and Euro driest. With 850s being just below 0C throughout that period and steady precip of pretty decent strength and assuming no more big northward/warmer shifts, I'd be quite surprised if at least Cobb and probably also Cherokee, N Fulton, and Forsyth didn't get at least 2-3" of SN on grass and elevated surfaces with as much as 4-6" in at least isolated spots on grass/elevated. Any opinions about this?

I agree with everything you just said. It’s so close. So close. Won’t take much of a precip rate to make it happen either and I think that’s the elephant in the forecast.

I'm not sure the date but we had a winter storm roll thru and basically initial call was 1-3 inches for many parts of Georgia north of I-20 but it busted pretty big with just falling from sky little accumulation due to warm nose and 850 temps just kept flipping between rain/sleet/snow... this feels like the complete reversal of that with much more qpf potential time will tell
 
Carl Parker on TWC is having an absolute field day talking about the 18z GFS. Getting everyone all hyped up with his 24 hour snow in ATL talk, lol.
