Wintry January 29th-30th ARCC Slam Dunk Winter Weather Threat

Through 00z Wednesday . No doubt the ugliest run yet . It’s like watching a slow death

18z vs 00z

Can you explain how it's caving to euro, I'm just asking not being sarcastic LoL. I'm just curious that's all

Trough wise. At one time all the models had the big vortex sitting over MN with a large broad trough across the south, the Euro was really the first to keep the vortex well in Canada and also really sharpen the trough to it's south. The other models are slowly correcting to the sharper trough and probably the low pressure wave next.

Of course I say that and now watch the Euro spit in my face.
 
I will be be very surprised if the Euro doesn’t come in with some really light shades of grey at 00z. It’s just not time for it to go *poof* completely yet. That will most likely come late Sunday night imo. Arctic fronts are just a really tough way to get snow. You would think they could update the frontal algorithm to make it a little more realistic in the long range

I don't know. To be honest looks like that all are matching up closer to the Euro and some of the esembles. I mentioned earlier when Kylo posted the 18z Euro Control that I expected a shaft zone if a small wave forms. Look at the FV3 and GFS tonight. The FV3 also continues to trend more separation. If this trend continues, it wouldn't surprise me to also see the two precip maximums and the minimum show even more. Can't say I don't like where I sit at the moment.

Is that a coastal wave that tries to develop off Nc/sc ? No wonder there so much more precip east of the apps
 
So folks in TN, MS, and AL either get a dusting to an inch at most, per the GFS, or widespread 2-4 inches. We've got a few more rounds of these runs before we can have a clear idea where this is headed.
 
Memphis get shafted in qpf on this run .. about the same in the rest of the areas if not a little better

Just FWIW, modeled accumulations stay about the same, yet QPF drops. That tells me cold air filtered in just a little faster this run. That is something to watch as we get closer and we clearly have a QPF increase down south. That is highly interesting as well.
 
Moisture looks fine here, but it's just gonna come down to the timing of the deeper cold air(pretty much for everyone east/southeast of the Southern Apps). Euro says I get almost 2 inches of snowfall(I'm sure a lot of this is probably being mixed with rain). Other models are meh. We'll see what tomorrow brings in terms of solutions. Still plenty of time for this to go one way or another.

Tomorrow, I personally want to see a trend towards a more progressive front.
 
Something also to monitor, the snow would begin right as rush our traffic starts in Atlanta. Factor in an Arctic front brining in the freezer behind it, and you have issues.
