It keeps pumping the SE Ridge. Maybe the weeklies update later will have some more information. But you can see the latest GEFS is stubbornly holding onto that -PNA trough. Looks like the Niña/+GLAAM MJO phase 7 composite. The SPV hype has no basis either, there is no evidence of a warming or split and it continues to remain very strong. This illustrates your point further: 3 Link to comment Share on other sites More sharing options...
Allsnow Posted December 9, 2021 Share Posted December 9, 2021 -epo continues to move up in time on the ensembles. The Pv looks to take a hit around that time which might allow for a -nao. It will take time but after next week’s blowtorch I do see some positive signs 2 1 Link to comment Share on other sites More sharing options...

It that wave 2 hit is true, it could help improve the pattern for cold/nao 2 1 Link to comment Share on other sites More sharing options...

Allsnow Posted December 9, 2021 Share Posted December 9, 2021 Next week still looks mild but the 70’s talk might be a stretch. The weekend is now looking to be the warmest on the models.

Parts of upper Michigan have received 2-4 ft. of snow and International Falls Minnesota reached -15 and -16 this week. Minneapolis expecting a snowstorm tomorrow. The cold wintry weather barely making it across the Canadian border. Typical of Nina winters. The upper Midwest is usually favored for big winters then along with the Northwest. 1 Link to comment Share on other sites More sharing options...

bluewave Posted December 9, 2021 Share Posted December 9, 2021 The 12z EPS keeps the -PNA trough near the West Coast through Dec 24th.This pumps up the SE Ridge.The -EPO ridge is centered too far west near the Aleutians and the -NAO is too far east based near Europe. 12z EPS for 12z Dec 24th 1 Link to comment Share on other sites More sharing options...
SnoSki14 Posted December 9, 2021 Share Posted December 9, 2021 LR still looks like crap. The only good thing is the very positive EPO goes away. Strong Atlantic blocking would do wonders in this pattern. Maybe it won't be a 2015 blowtorch but it still sucks. I think we'll get a favorable period in Jan and then March like 2018 though nowhere as severe. 1 Link to comment Share on other sites More sharing options...

You can have a -NAO and a SE ridge at the same time, I’ve seen folks say they can’t co-exist but that’s nonsense. It’s very possible and has happened many times before. That severely -PNA along with the SE ridge flex is going to be an issue. It might be a “gradient” pattern for New England….. 1 Link to comment Share on other sites More sharing options...
EasternLI Posted December 9, 2021 Share Posted December 9, 2021 I think ensembles are slowly coming around to the phase 7 la Niña look. I suspect the NAO look on ensembles right now is actually an atlantic ridge, similar to that composite, but spread is smearing that into the NAO domain. Any real -NAO wouldn't be until after the ball drops IMO. It's a slow moving mjo wave. I feel like any sooner progression would be too fast. Gefs is a little faster than eps. I'm thinking the eps has the better idea with the timing here. It's the very end of the 12z eps where the changes are just beginning. That makes some sense to me. 1 Link to comment Share on other sites More sharing options...
