Overnight EPS did trend colder for 12/24 vs the 12z run

If I can't get snow/cold: Still find a way to win:

This Saturday looks good to me, got 30 coming over ( high 40's) so I can send the younger ones out in the Pasteur to rumble around.

Waiting on one more set of runs and Booking tee times 12/26-12/27. It's any many mighty moe etc trying to peg the CAD days down.

On the webcam I see the slopes firing Guns on all cylinders. They are off to a banter start. Has to be pure powder up there this a.m., see some brave hearts getting it done in 6 degree air up at Beech. Hopefully they can get some below freezing nights , to maintain. Snowpack gonna takes some blows across the chin next couple weeks durig the daytime at a minimum.

And to join the choir. That block over to the west Alaska, just will not budge. Been there for what, at least 2 weeks now, and is still sitting there on the ens, as far as eye can see.

If we want to score something good near or just after the New Year, we will probably need to really shorten the wavelengths and cut something off underneath this retrograding -NAO block to time it up with one of these big CAD highs.

I say that because I don’t think we’re moving the Aleutian ridge anytime soon :/. I’d feel better about the odds of something like that happening later in Feb or Mar even but I guess crazier things have happened 🤷‍♂️

It feels like we've been talking about the immovable Aleution ridge for weeks, if not months. Yet, the eastern US, other than a few days, has been much below normal for weeks as well. Even this week, we start the first couple of days frigid, and likely go below normal again this weekend after a couple of days of moderation. What gives?
 
Its wild the drastic switching between runs now at 10 days on the operationals. I guess a weak CAD is better than a torch for some but is useless down here.
I really like that if we can build a good strong -NAO like we’re seeing signs of, it could get the job done as we head towards peak climo. There is serious cold building in Canada

It hasn't been in that spot for months.

Yep...we've had a very favorable pattern the past few weeks...

But our worst miserable winters have been when the gigantic aletutian ridge sets up shop where it's being modeled. I get it...."it's not winter yet"...."models are always wrong"...."CAD will save us"...

That big aleutian ridge will only promote a strong PV...but I won't bring that up. I'm not sure how we get out of this mess anytime soon.

Do you see a solid meteorological reason that that block will remain locked over that location through most of the winter?

I still think we see maybe a change mid January but that's more hope than anything. Our canonical pattern the past almost decade has been an aleutian ridge...that's the world we live in.

From early 2000's to roughly 2016 we had a magical pattern run....so hopefully this terrible aleutian ridge runs its course soon...hopefully by 2030.

Yeah, enso seems to have little to do with our problem the last 8-10 years or so (I'd argue 2014 was the last great winter for mby). Nino or nina, western troughing and the SE ridge prevails. And we're relegated to hoping for Miller B CAD miracles when a 50/50 forms. I think it's the warming of the ocean at the equator in the bad phases of the mjo/Indian ocean/maritimes that's the problem. Puts the forcing in the wrong spot for us and we get Aleutian ridges.

Nothing really to say about the long term. It's just more of the same, and I hope it gets switched up out in the pacific sometime in January.
