The se ridge builds through weeks 3 and 4. 850 temps anomaly are +1 week 3 (not bad) to +3 at week 4 (bad).

The one thing that is semi ok, is the ridge in the NPAC which may have some amplification, but the se ridge is on HGH on the weeklies. Hope they are wrong.

May I ask what they show for my region, in Southern ONT..just north of u, in terms of temps and precip.

I had all the models before but I stopped subscribing lol.

And I'm sure they show no blocking and weaken the AK vortex?

Thanks!

The reason lakes flash freeze like that too can be attributed to the fact that in order for a body of water to freeze, the whole volume has to cool to 4*C. Even if it's -20 out, the lake will not freeze quickly because the whole thing needs to reach that critical temp. Once those temps mix in, the top layer freezes and it works down from there. Maybe it was sitting on that threshold and finally broke allowing freezing to take place.

yes i'm aware.

it's still fascinating to see such a large body of water such as James Bay just lock up like that.

They show the same in terms of temp anomalies for your area. I can't see precip anomalies.

Wow how sad....starting to look like 2001 and 2007 again and I mean 2006-07 lol.

Perhaps we can squeeze in a few storms given the Active Polar Jet and Subtropical Jet at times though with the QBO finally starting to descend across 50mb maybe we can nudge in a bit of stratospheric warming later on in the season but the AK vortex is still holding its own.

Trade Winds are continuing strong across the Pacific and this combined with the MJO wave is really keeping the Arctic away from the East haha.

Lets see but I do think we'll see some progression of decent cold anomalies come early-Mid Jan.

Nah, things can turn around fast. If the 12z Euro mean pans out that whole mid month warming is big trouble.

The MJO has no culpability on the AO, btw -

Well I don't want them to sound any more valid then they should be. It's week 4 and prone to errors so they are not gospel. They have done ok with the overall pattern, but hopefully the ridging ends up better than shown. That would help the northeast.

If the PV splits then things could get interesting but the PV remains locked across Northern Canada, lol.

A -EPO would certainly help but I dont see any sustained cold anomalies, at least not thru the next 1-2 weeks across the East.

Still lots of time to change things.

Though it would be nice to get the MJO into Phases 78/1 and improve the Pacific to better establish a Aleutian Ridge and so forth.

A 7 day stretch upcoming with 1 slightly below normal day. Torch continues. Euro weeklies now show a building torch with possibly record warmth after new years. Disaster.

Man, sometimes you're just diabolical. T minus 10 minutes until Kevin takes the bait.

(p.s. I am more in your camp but the next week still looks at least brisker than what it has been... lol, "brisk" is our consolation prize... sure beats 60 F with high dews and sweating through one's sheets in Dec.)

I have to say based on the pattern and the Euro ensembles it really does finally appear we are turning the corner to a colder more wintry pattern. Today is the first day you can actually look at things and feel fairly content. The key is going to be keeping the EPO negative..We've had some bitter periods thru the yrs with -EPO and +NAO..Storm track may be suppressed, but we'll take our chances with that

The euro ens may show a bit of relief by day 12 but I'm not too excited. Still looks hideous beyond belief.

Yeah hard to believe climo at BDL is now 24/40. We've been nowhere near that.

I'm shocked that there is no talk about this system. A signal has been showing up on the GGEM,GFS,Euro ensembles and now the GFS ensembles.

There has been some discussion of it. I brought it up around noon today. There's not much to discuss except that its there but it could travel over bos or over mineapolis or be nothing at all. If things break right it could be a decent swfe for someone. Odds are slim though.

Seriously? Were in a DUMP pattern and were going begin discussions on a storm 240 hours who's current odds are about <1% of actually occurring. Not the place you want to come to If you want mythical, fantasy, wishcasting discussion.....

Here's a good place to check out... http://twitter.com/bigjoebastardi

Channeling my inner Ryan.... haha

ETauntonMA... you're thinking of the system at day 7/8

Maybe I'm thinking of a different system.

Makes sense given the expected ripping easterlies west of the dateline for the next 10 days... that should teleconnect to a stronger SE ridge in general through at least D18. With no MJO help, not sure what stops them, either.

Sounds like a decent pattern for New England.

It's all about the EPO. 70/71 Style, all the SE Ridge does is round out and allow for a nuke conditions like we saw yesterday. What we need is for Ecanada to stay frigid, lots of snow cover in Quebec. Euro ENS show this well.

I was wondering about this last night.

It really woul not have taken much to have made that into a pretty good event...maybe epic.

The preceding air was just so foul and warm.
