Timing is everything. Atlanta won't be at or below freezing until 3 am or so, at the rate of drop. The northern burbs will be there in an hour and a half. I'm now at 37.2/33.7, WB 35.8.

I don't know about that lol. I am sitting at 34.5/28 and continue to fall fairly quickly toward 32 here in Midtown. We'll be below 32 well before 3AM at this rate.

Isn’t that what Webber was talking about? 2nd snow growth zone? Sure is happening here

Yes. And the soundings on RDPS even showed it. RDPS is nailing temps on this. No one wanted to beleive we would be 14 and precip falling. But here we are

Really don't like that area of heavy precip down in southern AL headed straight for the ATL metro...if that stays as potent as it currently looks and it's below freezing here, might as well just lock down the half inch ice totals.

It's crazy to think that only 24-26 hours ago our area had 2 inch+ QPF. And yes, I've been watching that area now south of Montgomery since it formed off the Texas coast this AM.

One thing about the not-so-dry air. It's not dry over Georgia. Dewpoints and temps are relatively close, and even the lightest returns have been reported as reaching the ground wherever they occurred all evening.
 
Like others in my area have said, light frozen mist to drizzle which actually looks like really fine snow. Pixie dust. It’s been doing this for the last couple hours. Even though it’s very light, the ground and roads are whitening up. All this with no radar returns above

It was supposed to end closer to midnight but snow started a few hours earlier than anticipated. So I guess it cancels out. 6-7 (ha) hours of snow

Im convinced the light drops are trying to reform into dendrytes. They are falling again through minus 10 celsius air right after they come through the warm nose. Just a thought. Seeing some sharp pingers jet streak down as well in the flood light. This is as coldest at the surface ive ever seen it precip.

Went out and took some photos of the snowflakes that had accumulated on my cartop and they are indeed small 6-sided dendrites along with some plates. Was able to see a few columns in the photos as well.

I am at Dallas GA specifically right at 35.0 and pretty much wet-bulbed from rain we have seen and about 36 miles from Cummings in a straight line we shall see if the CAD and when because if make it makes it by 1-2 am right around the heavy axis is knocking on our door it could overperform or of course if doesn't of course not much of nothing.

Keep in mind also that right off the surface it's already below freezing. There will be accretion even at 32. With That cold air up to 950 to 925mb...temps will wetbulb easily well below freezing once precip starts in earnest.

Agreed. I expect with this new batch of rain, it will switch everyone Atlanta north to freezing rain. It'll be a close call for me. HRRR initialize too warm over my location on the last run.
