As Tippy and Will alluded .. there may not be much of a mild up at all

Thaaaat's not what I said.   Not speaking for Will...  I precisely stated that cold --> warm up of unknown magnitude --> colder pattern works S-E via the natural -EPO evolution.  That's the ultra compressed version of all those tl;drs from yesterday from me. 

If that interim warm-up ends up being muted ... then 'not much at all' will be correct, but I didn't actually assert that's what's going to happen. It's still possible that we spend a couple of days above normal, perhaps exotically so, if you believe some of these recent GFS/ens members.   

In fact, some indicators overnight attempted to go back to the more +PNA look as opposed to the -EPO.  Yesterday, all ens means moved en masse toward the -EPO.  The new EPS mean is splitting.      

The only thing we know of higher confidence ( still ) is the breakdown of the mid Pacific ridging/height anomaly, which has been transitively ...well, fucking up the works. It's been conducting the music into a cold melody over the continent over the last several weeks, but the rhythm of the wave spacing has been negatively interfering with storm system genesis. etc...  not going over that again. 

Seeing that breakdown will be a good thing ... in theory. I mean, if we're juggling between -EPO (standard variant) vs +PNA from these ens visions, neither is climo "bad" for winter event enthusiasts.  So we got good problems in that sense. But, we have to get on the other side of ~ the 5th-7th, first.   By the 8th, the Pacific mode change has completed and the ens systems will prooobably have a better handle on what's happening on the other side of the pattern change door by then. 

Speculation:  It still looks cold above STL-DCA latitudes between the 10th and 20th.  If the +PNA ends up more reality than the big -EPO, we may conjure an event entering said PNA phase. If it's the EPO version, we may go (unknown) warm first, than eventually/have to wait that out.

Yeah, I guess after the 12th ...but the timing of all this isn't set either. it's just where the indicators look now...  again again again, we need to get on the other side of the Pac change window

I’d expect anything post-1/8 to be pretty poorly modeled right now with the big PAC changes going on. Our biggest chance at a monster torch day or two would be just beyond that…maybe 1/10ish if we warm sector cleanly with no precip like a few OP runs showed. But we’ve also seen some CAD looks around then too. So we wait. Heights will be way above normal but we don’t know on sfc temps yet.

...as things stand right now at least the next 7-9  days are likely to not have any significant winter weather . At that point it will be approaching the middle part of January...

thats a bold guess

And the can gets kicked once more. One more pattern delay after that and we’ll be looking at end of January

The 7th through the 17th. Not a cold look. 17th is 1st . Too lazy to change it.

Wondering how the glass overflowing wolf will try to spin this one.

This is legit unlike the other ones.

Happy 2026, looks like winter is done for the foreseeable future.  It was a great December at least

Don’t you read anything the Mets say on here . You can’t just rip and read and assume warmth

Winter 2013-14 was excellent overall, but January was major frustration.  It was significantly BN for temp, AN for precip, and the 2nd least snowy of 130 Januarys at the nearby Farmington co-op.  That's a near-impossible trifecta.

[jbenedet]

The -PNA is fading but so is the -NAO…Not seeing anyone pointing out the latter…

I don’t know why these phases have been in sych in recent years but it continues…

As for the CPC forecast beyond day 10, I think the +AN risk is greatest along the east coast losing the -NAO, and with the west coast ridge axis being west of Washington state…

It’s a long wave pattern where upstate  NY into northern VT can do very well, snowfall wise. The whites of NH into northern Maine as well…latitudinal Gradient vibes returning to New England. This means a poor pattern for sig snowfall chances in the major metros from Philly to Portland.

although, Jan 2014 was fantastic for SNE

[dendrite]

Def looks warm for a good 5-7 days starting around the 7th. The waters get a little muddy after that.
