Things are looking promising for a big December.

The only thing I disagree with here is the negative NAO. Our big -NAO years like 09-10 and 10-11 were near the solar minimum. We are descending, but solar activity is still a lot higher than it was during those years. I would lean towards more of a neutral to slightly positive NAO. The more important factor is the fall pattern, we have diverged from the bone dry fall pattern that continued into the winter. We saw a mid fall shift from an extended dry stretch (leading to drought conditions), and it has shifted to a stormy pattern with frequent coastals. This combined with the other factors mentioned has me very optimistic about this upcoming winter for New England, even if the negative NAO idea doesn’t pan out. When I think of a big snow pattern the first thing I think of is NOT a Greenland block, it’s a tall ridge over Montana.

PDO is still solidly negative, but it is less negative than it was last October.

I got buried in 12-13

I am all in. I believe something big is going to happen this winter.

I am very excited about what I am seeing this fall. It is still early but things are looking better and better for a big winter in New England.

Agree. We are already seeing some promising signs with a transition to a wetter pattern, which did not happen until Feb last year. Weak east based Nina, early northern snow cover build up, the early signs look pretty good. The PDO is negative, but it’s less negative than last year (-2.4 September 2025 vs -3.5 September 2024).

Yeah, I was of the impression the debate was weak La Niña vs cold neutral and everything else was off the table.

You can tell it’s bullshit by looking at the south. It’s not going to snow a lot in the south.

Way too early

How come? I know you don’t like the 13-14 analog, so I’ll bring up a different year that is a better PDO match. Jan 2022 was strongly +PNA with a -2.7 PDO

This is the most excited I have been about an upcoming winter since probably 21-22. East based La Niña AND that warm pool off the WC and in the GOA??? I like the look of that.

I am starting to think this has the potential to be a big winter in the east, especially New England. I like what I am seeing with the warm pool that has developed just off the pacific NW, that is something that was present in our big +PNA/-EPO winters. There are also signs that the La Niña is going to be east based, which is another point in our favor.

Looks like a gradient pattern.

Cold ENSO 3.4 and warm ENSO 1+2 is still a La Niña, just a different kind of La Niña (modoki La Niña). At times it didn’t behave like a La Niña, but that is more because it was so weak than what ENSO 1+2 was doing. In Feb though the storm track was consistent with a modoki event. In modoki events storms tend to take more of a northern track, which is why they are unfavorable for big snows outside of NNE. There was a lot of low level cold though, so it got icy.
