Big time -AO on 0z GFS ensembles hr96-300. probably <-2 std. 

180-192hr to me looks like big ice somewhere as there is arctic blocking/ridging, and the PV underneath of it near the Hudson Bay and SE Canada, then a ridge riding over it in the Mid-Atlantic from south-based+NAO. -AO's are our best index pattern for snow though, so it's possible it's snow north of DC/Balt in the normal climate zones and ice south.. still way far ways out.. it can go either way but with a <-2 AO less chance it's rain, imo. 

You nailed it Chuck, if it materializes.

-2 to -4 AO signals are quite often precursors to significant winter weather events.

Individual ensemble members are all over the place in the medium range (0z). It's been really rare to have a wall of strong High pressures in the Great Lakes/southern Canada, while a high qpf low cuts into the Mid-Atlantic or Northeast. Call it a decadal pattern. Let's see if we can break it!

0z EPS is frigid Jan 27-29!

I love how the Euro completely pulled the threat it was advertising at 150hrs at 12z and 144hrs at 18z on last night's 0z run (it's not there on 6z either.)

So I  feel even more confident than yesterday in saying the Euro fooked us again. Lol

New 3-4 week CPC keeps us cold to mid February

"Winter before an El Nino the next year" has been working out great this Winter so far. Here it is for February:

If there is cold air, there is always hope!!!!!

Thursday  12" snow on 1-25

Yesterday, snow disappeared but 0 F. on 12-25.....   I said, no-way.

This morning, Euro has been re-born to 18 F. on 12-25......  LOL again

There is indeed ensemble support for jan 25-27 and again 28-30. Don’t know why some are saying otherwise. Jan 22 is the only threat that doesn’t have much support.

Those ensemble mean snowfall maps @mitchnick posted were the best I've seen since

I always liked Christmas, but make that 1-25!

Jeez, the mood swings and tearing of hair, gnashing of teeth in this place!!!  You'd think we've gone from a HECS to a 70 degree wall-to-wall torch for the rest of the month given the tone of some posts!  Yeah, I know, should be used to it by now in all the years I've been on this forum.  But still.  I checked some of the models and read some of the better posts in here and...honestly, you cannot ask for a much better placed to be at this point.  As several others have said, and I agree, the potential and look starting around Jan. 22-24ish is great!  Obviously, that's no guarantee we score anything (the usual caveat statement!).  However, every model has been showing at least one and in many cases more than one solid event from next weekend through the end of the month.  The ensembles likewise look solid (I think @mitchnick posted the snow means earlier?) and have for a little while now.  This isn't some one-off where a stray deterministic run dumps on us one time and then it's gone forever and ensembles showing nothing.  This is a fairly consistent indication of waves running into solid cold air...maybe at different times each model cycle but it keeps showing up and it's not being can-kicked.  It's kind of like how @Bob Chill says...sometimes you see great looking ensemble means but "under the hood" there's not much there when you should see some good hits, which raises red flags; other times, you see great looking ensembles and there ARE good hits in there along with the same from deterministic models.  So yeah, I gotta like what's under the hood here!

"Winter before an El Nino the next year" has been working out great this Winter so far. Here it is for February:

If we can manage a BN or even slightly BN February, (which would be pretty wild considering November - January was also BN) coupled with the STJ waking up… we could see a monster before the pattern eventually breaks down. Obviously all speculation but the ingredients seem to be coming together for the January 24 - February 10 timeframe to possibly be very special.

Yeah I was concerned about pac energy breaking apart the +pna and torching canada, but recent ens runs stop short of doing that and still maintain western ridging. Canada will warm up yes, but we may stay NN/BN in the east and during this window that’s all we need.

Euro weeklies trended much better for us in feb even! It wants to keep the good pattern going through feb until losing it around 2/23
