I wonder with the amount of lift possible if there might be some thundersnow somewhere.

Definitely think so. It's a very sharp trough with a lot of instability ahead and even just behind the front. Some of the convection/thunderstorms will probably move northward into the cold sector.

Let’s not get carried away here. This is not a triple phase from tornado to snow

LOL, I know. I just thought the alignment of the snow looked similar and this weekend is the 29th anniversary I wanted to throw a little modernweenie into it. ?
 
RGEM might be off it's rocker, but it's trying to throw down snowfall-QPF equivalent rates of up to nearly .5 inches per hour in NE AL through NW GA tonight. Even at ratios of 6:1, you're still talking over 2.6 inches per hour of snow.

Was just looking at that. I'm in NE bama. Those look like insane rates.

I mean I am not seeing much to suggest any accumulation outside the far northwest suburbs of Atlanta. Doesn’t mean it won’t. Just means it’s very unlikely.

Agreed. North and west of the Muddy Water & north of 20 are your best bets in GA.

Meanwhile, my polyethylene cover to line my walk to protect my tulips will work out great.

I know most people don’t care, and this is probably banter, but these bulbs were from my beloved late uncle’s yard. We lost him in 2013 and these bulbs have come back every year since. Gotta keep the streak alive!

And abruptly shuts off the waterfall as it crosses into GA

Question for those knowledgeable, I know @GaWx was speaking to something similar earlier, but what is up with the GFS operational map not being in line with the precip map? The temps support the snow sticking, but it shows no accumilations. Thanks

Model is predicting heavy rates won’t last long enough for measurable snow depth. Moisture pulling out fast, in other words.

Because the averaged precip map is garbage. That isn’t Simulated radar.

yep, TT is showing the prior 6 hours precip (6z to 12z precip for the 12z timestamp)
on the COD site, it shows measurable precip is about over for Atlanta around 9z, and by 12z it's long gone racing to the northeast, so based on that we can see that almost all the precip shown on TT site for the 12z timestamp is actually happening from 6z to 9z when it's too warm for snow. very misleading map, but sure it pretty to look at lol

NWS Wakefield calling for accumulating snow in Richmond now, dang! Can’t imagine the sun angle and warm soil temps are going to help, so hopefully whatever falls is really heavy, though.

Saturday
Rain before 11am, then snow. Temperature falling to around 29 by 5pm. Breezy, with a north wind 13 to 23 mph, with gusts as high as 37 mph. Chance of precipitation is 100%. New snow accumulation of less than one inch possible.
Saturday Night
A chance of snow showers before 7pm. Mostly clear, with a low around 18. Blustery, with a northwest wind 15 to 20 mph decreasing to 9 to 14 mph after midnight. Winds could gust as high as 31 mph. Chance of precipitation is 30%. New snow accumulation of less than a half inch possible.

You moved to Richmond ? Dang !

Why not a little more?!
 
I mean I’m not gonna lie I’m skeptical where I sit in Maggie valley. We are 3,006ft but models only really show snow for 2-3 hrs. Meanwhile the hrrr continues to show 2-3 inches here. It’s going to have to be extremely heavy to overcome a warm ground to see 2-3 inches in just a couple hours. I’m here now guess I’ll soon find out

1. Lmao, I highly doubt there is going to be 4” of snow almost down to Columbus, GA, as this 12 km 18Z NAM map shows.

2. I think it is best for me to not post the ridiculously overdone (for ATL) 18Z GFS Maxar clown map. There are issues with low resolution as I noted earlier on these maps.

Larry, how do I measure 4 inches of snow that melts as it hits the ground? My snow board just gets wet! Do I describe it as liquid snow? Phantom snow? Ghost snow?? Air snow, but not ground snow? Is it really snow if you can only see it as it falls?? This is an official request of Mr. Abacus!
