That is the same picture.

Winter 2025-26 Medium/Long Range Discussion

Yeah you're all going to want to watch out if that phasing trend continues in the west with this weekend system. Potential for a major short range bust in the positive direction and a major winter storm for the sub-forum. -
As someone living in OK, holy shit at that 00z GFS. Also as someone watching the potential for the Mid Atlantic, holy shit at the 00z GFS.

MO/KS/AR/OK 2025-2026 Winter Discussion
andyhb replied to stormdragonwx's topic in Central/Western States
Massive storm for pretty much all of OK on the 00z GFS. Even at 10:1 that's approaching record-breaking territory. -
The PDII comparisons starting to flash into the picture.
-
I do think there's a logical limit to how far north the mixing is based on how strong the Arctic high is initially. Someone is going to get absolutely hammered with ice though if the SE ridge amplifies significantly.
-
If the dynamics get super charged by that northern stream wave, it increases the chances of a 2'+ jackpot for someone, if you want it in real weenie speak.
-
That northern stream wave/lobe of the PV continues to get stronger with each passing Euro run. Not sure if that continues, but it absolutely raises the ceiling on this if it phases. I should probably add that it also may induce more mixing concerns for areas further south, as it would lead to SE ridge amplification and WAA aloft.
-
That run is an absolute disaster for the Carolinas ice wise, particularly upstate SC, Charlotte, and most of the Triad/Research Triangle metros.
-
GFS is very heavily suppressed. That's the number one failure mode with this storm by far with a near record strength Arctic high to the north.
-
I'm telling you all what you don't want with this storm, and it's this centered over the Atlanta metro via the 00z Euro. Do not be in the ZR swath with this thing.
-
-
1.5+" of ice for much of the Atlanta metro/N GA thanks to an extremely strong CAD wedge. This is a nightmare.
-
Absolutely historic, devastating ice storm on that 00z Euro run for a wide swath of the Southeast. You do not want that verifying.
-
-
Bordering PDII levels on that UK run, deeper storm with a long period of heavy snow both in the WAA region and the deformation zone.
-
And for the knockout punch...
-
If you want a major storm, you want Tomer Burg talking like this. End of story.

-
Big west based -NAO with a lot of cold air present usually equals some kind of pay dirt, just uncommon in a Niña.
-
What in the 2010 hell was that AIFS run?
-
That is a catastrophic ice storm on the 12z Euro for this region and particularly Atlanta.

Ok but seriously, what in the actual hell happened with that run? -
Nov 28-30th Post Turkey Day Winter Storm
andyhb replied to Chicago Storm's topic in Lakes/Ohio Valley
Jackpots of over 16” in central IA and S WI with this, seems like many areas got over 10” by the end of it.
