Pattern December Doldrums 2025 🎄 ❄️

We’re currently watching an S2S tug-of-war play out between the +AAMa/anomalous westerly flow in the tropical Pacific trying to extend the Pacific Jet vs -EAMT & beta advection from the ridge itself trying to constantly retract the jet and shift the Aleutian high westward.

These 2 things competing against each other plus La Nina is why we have a stationary wave pattern w/ Aleutian ridging in the North Pacific

We honestly need to extend the Pacific Jet again to break this stalemate, because those +AAMa aren’t going anywhere. Hence, retracting the jet doesn’t fix the issue.

You made your point 10 posts ago.

You've always been one of my favorite posters, but I am tired of logging on and seeing passive aggressive strawman-type posts.

This isn't just you. But we're going to put a stop to that. It just makes everybody mad. I'm going to call out every post where I see it from now on.

If you or anyone else has a beef with how someone responds to a post of yours when you are providing good analysis, then PM them and work it out or let the staff know that it's bothering you. Or I can set up a winter battle thread and we can have a free for all.

I am so sick of the constant passive aggressive stuff every time the weather turns bad. It is like clockwork every winter. The staff is going to start muting posters if we don't get that under control.

I don't care if you don't like my posts....that's a you problem. Piss off with your passive aggressive attacks on me...just because you are red tagged doesn't give you the right to directly attack people. I didn't directly attack you or anyone else...

But I get it...sarcasm is lost on the stupid.

Do you think it will extend enough?

The 12Z GFS -NAO for week 2 remained strong:

Per the maps, below, it looks like the 12Z GEFS likely has about as strong a -NAO as the prior 3 runs, if not a little stronger:

Classic NAO calc. is based on pressure anoms diff between Iceland and Azores: I see ~-2.2 std devs:

for those who care (me)

christmas afternoon wedge/chilly/not AN:
00z EPS --18/50 (36%)
06z AIFS-ENS -- 11/50 (22%)
00z GEFS -- 8/30 (27%)
06z GEFS -- 9/30 (30%)
12z GEFS -- 8/30 (27%)
12z AI-GEFS -- 0/30 (frown %)

side note, welcome to the party, AIGFS and AIGEFS. looks like no snow products from those yet.

55-60 is a W for Christmas to me at this point
 
If we can get a shortwave to eject east on the heels of a 50/50 low around December 30/31… we might have a tiny window to score. That’s what the 06z euro AI was showing and 12z euro shows it, but need the shortwave to speed up a little. Other models hinting at the same thing around the same timeframe. Something to watch for at least.

note my numbers are fairly generalized and not everyone within wedge zones was wedged in the ones i counted. a notable number of members had the idea but didn't execute very far south.

We are inching closer and closer to turning the entire week next week into a foggy insitu mess

12Z GEFS strong -NAO that starts in just 5 days and is the strongest -NAO for days 5-16 averaged out on any GEFS run back to at least Oct 31st:

I’m sure the MJO will go into phase 5 or something, to counteract this beautiful-NAO
 
It looks like Christmas might not be sitting by the pool weather for the RDU area after all. Temperatures on the Euro and GFS look to be about normal with highs in the mid 50s. It looks like it will be a boring day weather wise.
 
Natural gas closed up nearly 4%, easily its best day since Dec 5th. This is largely based on today’s forecast speculation that the forecasted dominant warmth may not be as widespread, intense, and/or long lasting in the E US as thought yesterday.

You sit by the pool in the mid 50s F?

Just heard opposite during lunch time . Guess there basing this off NOAA s winter forecast
 
So if we all come on here and post that we wish for 70 degrees in January, does that mean we will get cold?

Check out the widespread much lower H5 for nearly the entire E US on the 12Z GEFS as of 0Z 12/30 helped mainly by the apparently even stronger -NAO:

I'd like another New Years storm. Stalled out front, impulse comes up it into cold air. Not out of reason...if there's actually a front out there...and if the front stalls...and if a low forms...and if the cold air comes on down... hmmm...about like any southern storm chances....iffy, lol.
