Even the EPS isn’t far off. Can’t see the strat on it but sets up a more dominant lobe of the tropospheric polar vortex over Hudson Bay. The Indo-pac forcing is forcing this strong +TNH signal, in some ways similar to 2014, but the East might get lucky here as a weak +EAMT event occurs around day 7 and gets the pacific jet just far enough east to be in a favorable location IMG_3782.pngIMG_3779.pngIMG_3780.png

I lived in Wisconsin back then please tell me the story of said storm
Major winter storm with widespread 12”+ total from Oklahoma/Texas east to the Carolinas. CLT saw its all time daily snowfall record set with that storm at 12.1”. The snow was pure powder with temperatures in the mid to upper teens throughout
 
Yea, i'm worried we're gonna overcook the cold press, but then I think there's no way we verify as cold as the Euro shows. It's probably best to keep the cold press shown as depicted(overbearing to the point of suppression) for as long as possible, b/c it will mostly likely slack off some in the next couple of days.

Right now, The 12z GFS, 12z GEFS, 12z Euro, 12z Euro AI, and 12z EPS, 12z ICON, 12z MOGREPS are all either too strong or borderline too strong/too far South and East with the cold.

The 12z CMC/00zSpire/12zCMCE/06z GFS graphcast are the the only models still showing concerns with too weak of a cold press and a baroclinic zone too far North/West.

Don’t know if I’ve ever seen a coast to coast temp map like this before! The US becomes Siberia 👀 👀 👀

For perspective from the POV of Houston, using it as a yardstick against the 14 F in the model above

one time growing up I experienced (hid in the bushes for warmth waiting for the school bus, as was our street's custom when very cold) 10 F in Houston. The next lowest in my 18 years there was 17 F.

This one always worries me. While trying to nail the pattern down it’s one that can give you +-20 degree swings between cycles. Hold on tight
Yea I feel like in the last 20 years there's been several times we were widely forecasted to be in this type of setup in the day 6 to 8 timeframe... and they have literally always trended the wrong way for us,(warmer/wetter).

The good thing right now is that we may need some shifting back with it this time since everything has went so extreme with the cold press.
 
The shifts East is what's been money for us. The concern is too much shifting South with the cold press... Feel like that almost certainly has to be overdone with the lack of blocking and the fact that this is essentially the main polar vortex we're talking about. We need an arctic high drifting/building west to East across the Northern US, not across the Gulf coast.
 
With the amount of cold being forecast this far out on ensembles. I’d like to see this trend stop. This has all the hallmarks of dominant dry cold. Something many here hate to see
Southern Illinois? I bet you don't like this look. Wouldn't you prefer some kind of apps runner?

In a perfect world yes. But past day the dry cold has dominated our trend. Given another day it will dominate for y’all as well. You want to see it hold up a bit or even move more NW. this is a pattern that favors more SE trends than NW
 
Is the Euro the only one showing a signal? So far as I have scanned thru this thread its the only one I notice being talked about.

Yeah, no doubt. I will be happy for folks south of here to cash in but it hurts to be north of the best snows when you live far enough south already! Mind numbing when that happens. @dsaur likes to remind me of one of those events! :D
 
Sorry - had to post this from the Euro. 2.5 inches of ZR near Valdosta?? WtfView attachment 163009

Tallahassee’s mossy oaks would be wiped out by that (not that it has a snowball’s chance in hell of happening, LOL). But one of the craziest model runs I’ve ever seen.

Two feet of snow would make up for two straight snowless winters, truly. Of course, it has no chance of happening but I haven’t seen a model run like this in a decade. 😂 And this isn’t even hr 384 on the GFS, this is actually around D10! 👀

Might be time to take the plunge for WeatherBell.
 
Since it was allowed to go out further than 240 hours lol
You know, it’s funny because I do think the Euro’s reputation of being Dr No and not showing fantasy storms in yesteryear was partially because it did stop at D10 and thus wouldn’t ever show all the goofy solutions you get with the GFS at hr 384, etc.
 
Was looking back at some archived model data I saved, and the Pangu-Ens mean did absolutely magnificent with the low track & temps with the last system. The run on 1-7 @ 12z was (anecdotally) the best run of any model that cycle with low track, 850mb temps, and 2m temps.

Will definitely be pulling it back out for any threats upcoming!

Yep. Plus it only ran 2x a day so it had half as many opportunities to spit out some weenie fuel.

Did it stay locked in or did it vary with subsequent runs?
