It was a slow trend toward the icier scenario on the euro but still not enough for big impact...maybe up into W ME. Some front end ice too for interior CNE.

Ukie looks more like the 00z euro keeping the southern energy more consolidated and west so you end up with a cutter anyway albeit with CAD out in front of it...but wouldn’t be that much snow on that setup.

GEM is definitely an icy look over interior even if verbatim the 32F sfc isotherm doesn’t make it much past NH/MA border. Lot of mesolow showing up there. Still a bit skeptical until Euro gets on board but it’s plausible.

GEFS d15 pattern is definitely very good. But obviously not agreeing with EPS. For the first week of January, we will definitely have to hope for good NAO blocking to set up or we’re probably going to struggle with an AK vortex out on the PAC side.

Temporary one eyed pig setting up over AK early month too. We need the NAO to set up then or we’re gonna have a useless first week of January. It does look like the pig retrogrades west so it’s not locking in.

A majority are rainers on the EPS but you can still see quite a few wintry scenarios too mixed in. The spread is large.

Still crap (ensembles...06z operational doesn’t go out far enough)...though it’s slowly trending the right way. Problem on the euro is it keeps the energy pretty consolidated in the southern stream and then phases with another shortwave coming in behind it. It’s slow and consolidated compared to other guidance.

We’ll want to see the northern stream clear pretty far south ahead of the southern stream to have significant winter wx into SNE I think. Need the high to build in a real airmass otherwise it’s probably not enough down here. Having deeper cold push would help NNE get more snow too which they need badly.

Hard to go bullish on wintry wx until euro looks better. Most other guidance is coming on board though (Ukie/GFS/GGEM) with icing to at least interior CNE if not northern SNE. Problem is the euro is still holding a lot of that energy back and consolidating it allowing the storm to wind up to the west after the northern stream clears out. May or may not be its old bias in effect...but we’ll see.

Quite the change at 90h on 06z euro. Even compared to 00z

Feb 1950 was a big month too in the potent '49-'50 Nina. Best month of that winter after the warmest January on record (still stands as the record in many sites around here)

2001 was 2nd best month behind March.

Good La Nina Februarys (at least off top of my head for interior SNE)....2001, 1996, 1975, 1972, 1956. You could technically say 2011 and 2006 were good, but they were pretty choppy. I guess 1996 might fit in that group too. Feb 1956 would be the bullseye we are shooting for though. Monster month.

Yeah, it's just the timing of the epic grinch distorts the "feeling" of it. But I personally enjoyed Xmas eve a ton...it had the reggae weekend vibe at the ski resorts....we were burning the firepit outside with temps near 50F and deep snow cover. My son making and then destroying a snowman, lol. Xmas day itself though was a total bummer. No denying that. 2017 this was not.

This was admittedly worse than most grinches. There was deep snow cover across a huge percentage of the posting subforum after a pretty big time storm on 12/16-17....those types of storms don’t grow on trees, especially first 3 weeks of December. Then the progged NAO blocking for late December started to look crappier in the days approaching the grinch storm, which caused us to lose 12/29 and then recently it looks worse in early January. So a lot of people are playing the “pattern pushed back so it’s bogus” card. Even if that isn’t really sound reasoning.

Grinch storm broke a lot of people. Kind of ruined the vibe of the good start for many peeps...so I kind of get it. But that isn’t an excuse to start punting January. Especially when model guidance is all over the map...and these same models basically wanted to puke all over December too. Then they started getting optimistic, and then tried to pull the rug out again early in the month.... Remember all the panic of December not panning out after 12/5 disappointed some folks and they were complaining that the pig was coming back by 12/15 or 12/20? Lol...then we got a major snowstorm.

Lol it’s definitely a small random town.

Even in Holliston I have 17” for the month with 15 days of snow cover so far. Both solidly above climo.

That's actually a decent PAC, look at that AK ridging. It's a classic massive poleward Aleutian ridge...-EPO/-PNA/-NAO pattern. The NAO is crucial there though for avoiding some cutters, but the PAC is keeping a lot of cold in Canada there.

A true davis strait block will trump a shitty PAC, but a garbage N ATL ridge won't. So it all depends on where it sets up.

Cancelling January is just as bad as locking in 2011 at this point. Guidance isn't consistent at all right now.

Euro did change a lot aloft though. It definitely made a step toward the less phased scenario even if t didn’t come all the way there. It wouldn’t take a whole lot more to bring the wintry scenarios into play. Check out 108h today vs 120h on the 00z run...notice up in Canada you see today’s run having a bunch of energy sheared out north of Lake Superior...that also causes the main trough to the south to become more elongated and positive tilted

Verbatim it’s mostly just in the high elevations but in reality it could be more widespread. I’d like to see the isobars orient the sfc front more NE to SW though for a classic icing event.

I’m not even sure what the 12z Ukie is doing now. It basically leaves about half the energy behind but still has some ejected into the southeast. Almost looks like it would have trouble even getting the storm this far north. That could be an icing setup though... Lol

Ggem whiffs on the phase too now but it still tries to track the low pretty far west. However, because it whiffs on the initial phase, it allows some high pressure to build in ahead of it so it starts to act more like a SWFE in NNE. Esp at the surface with icing. Trend that a little more and there could be a snowier solution on the table.
