A 2-4 week period of warmth in early December makes sense. I think we rock after that. Could see a repeat of what we saw this month with very warm temps followed by a crash, cold, and this time- snow.

Still think this. Totally fine with a crap pattern for the next few weeks. Then we reload.

I wouldn’t mind a can kick as long as we do get a supportive snow pattern eventually (which I do think will happen with that high latitude look plus MJO progression). Climo is so much better by Dec 15.

Hate that blob ridge near the Aluetians...."usually"......but with a ridge bridge from the EPO to NAO and a split flow coming onshore western n america, that can overcome the central PAC pig ridge. I like how said ridge (base state?) is feeding the EPO. We take.

It's a prominent feature of a Nina. Keeping it somewhat in check is a constant battle for our purposes. Ideally it would be more poleward over AK rather than broad and flat south of the Aleutians. What the models are depicting is a bit of both over the next 10 days or so, and the vortex near Okhotsk will continue to influence the character of that ridge. We need the -NAO to be legit and west based to counter the tendency for a trough out west and to keep the SE ridge flat.
