It is reminiscent of a couple of winters ago when the ensembles and operationals kept showing the MJO going through phases 8-1-2 at high amplitude in the long range over and over again for months….it never happened. I believe it was the 2023-24 winter

This ties in with the very persistent trend of dry/drought we’ve seen since the tail end of summer, 2024 you just posted about. The most persistent dry pattern we’ve seen in this region in over 24 years. Every time it’s looked like we are going to go into a wet pattern again, it fails

Mentioned this in response to @Bluewave post in the NYC forum, but we haven’t seen a dry pattern of this magnitude since 2001-2002. It began in late summer, 2024

Looks like Ray @40/70 Benchmark was right about the SPV strengthening in January……

The op EURO/EPS was absolutely awful with its big west-based -NAO block it kept insisting on for days, run after run for early-mid January, which is totally gone now. A really bad performance with that

As of now, I’m seriously doubting that we see -NAO blocking to go along with the anticipated -EPO/+TNH pattern later this month. +TNH very strongly favors a +NAO/+AO/SE ridge regime as both @40/70 Benchmark and Eric Webb mused. Also, @StormchaserChuck1 found a very strong tendency for a positive NAO when the EPO is negative the last 10 years….

Nice write up. I think the -EPO/+TNH just after mid-month into late January is real. I also think the cold is real. The risk again would be the +NAO/+AO/SE ridge tendency that comes along with a +TNH regime. I can see a gradient type pattern with overrunning events and SWFEs. The question, as always, will be where does the gradient set up? New England would obviously be the safest on the cold side in such a gradient pattern. Probably can get a better idea of how it’s going to play out the next couple of weeks

All about the clout. Guaranteed, 100%, come mid-late January they completely change their February forecast to very cold and very snowy from the Midwest/Lakes to the east coast no matter what. No doubt in my mind. They need the subscription money to keep coming in. They’re in too deep now. They’ve turned into a franchise that’s all about the like clicks, subscription money, views, follows and retweets like a few others are. It’s a shame…..

What a God awful performance by the op EURO and EPS on that big west-based -NAO block for early-mid January. Epic failure. Good lord did they fuck that model up with the “update” years back. It’s sad

Yep and he also followed up with this tweet…the +AO (aka “NAM”) and +NAO with SE ridge risk:

Therein lies the risk if we do in fact see a +TNH pattern take over just after mid-January….the AO (NAM). Here’s Eric’s new tweet on it, but +TNH favors the AO going positive along with the NAO going positive. And you already mentioned the SE ridge risk with it

t’s starting to look like a +TNH (-EPO) develops maybe just after we pass mid-January into late January. The caveat with +TNH patterns is that they are also correlated with +AO (+NAM), +NAO and a healthy SE ridge. So, while certainly arctic cold, it’s not going to be a “KU” pattern with ‘big dog’ snowstorms up the I-95 corridor, DC-BOS as some folks on twitter are saying. IF said +TNH pattern (-EPO/+AO/+NAO/SE ridge) develops just after mid-month into late January, it would argue for overrunning events and SWFEs. The question then becomes does it favor New England? Or PHL/NYC north into New England?
