That is interesting....KBOS went to crap in the spring too after last winter. You can see when they fixed the REALLY bad issues back in spring of 2020, but then the step down to crappy (but not quite as bad as before) in spring 2021 and now getting back to normal in fall 2021

EPS basically cancelled it too...maybe a brief torch around D10.

Actually pretty decent mean for 6 days out...has measurable snowfall for most of the area.

Not the final solution of course....that was close to something a lot better. Verbatim though, prob just some light snow mostly S of pike on that run for Sunday.

Euro is going to have snow here on Sunday...possibly into Monday too...backside energy trying to dive in so we'll see if it goes to town, but even the current solution has light snow falling on Sunday in SNE.

PRob going to be getting good upslope snows on Friday too...even over at BW. This looks like a pretty robust event because there's a lot of deeper level synoptic moisture associated with it.

GEFS actually cancels any torch at all....just reloads the cold before the mild air ever has a chance to make it into New England.

Ukie with a little nuke next Monday. Canadian trying too....GFS not interested.

Yeah we know the caveats. Guidance has been volatile so nothing is locked.

Pretty classic “good La Niña” look on that run where the N tier gets cold and active storm track. You can see the gradient there on the 850 temp anomalies (and it’s easy to see at H5 too). That’s definitely what we are hoping for. It helps that the Atlantic isn’t horrific...almost kind of neutral look there. PV also displaced a little south toward our side of the pole.

I’d be surprised if we don’t at least get the “first flakes” monkey off our back for many of the areas who haven’t seen them yet. Prob a lot of popcorn snow showers around with that upper level cold pool even if we don’t get a real storm.

EPS looked really solid last night. We’ll take this for sure....

May have to watch for a follow-up clipper if that Sunday/Monday system gets crunched offshore. The cold definitely has been getting prolonged on guidance. Seems like we may only torch for a brief time now...hopefully that holds.

The anomalies up there were incredible that winter. That had to be like a minus 3-sigma event.

This is the same "system" from the post I made several days ago....interesting that it has reappeared recently (GGEM has it too but just a day earlier).

Maybe...there's a lot of uncertainty in our area actually for the first several days of December....several pieces of guidance are trying to drill a localized cold shot via a PV lobe into NE while the upper plains torch away....that could shorten the amount of time we have any real true torchy weather. Here's an example from the 12z GFS below....yes, its clown range so obviousl this can/will change, but we don;t know which direction it will change. Maybe we end up torchier, but we could also end up colder/snowier like the 12z GGEM shows

Most of those early Dec 1995 days in BOS were below average. I think we only cracked 40F maybe twice in ORH during that stretch.....but the real snow started on 12/9 when we got about 5 inches and then some ZR (BOS changed to rain in that one). We did have some leftover snow from 11/29/95 still in spots though before 12/9.

Yeah the upslope spots will see some action on Friday/Saturday. Pretty good ULL spinning there nin N Maine and S Quebec for a couple days wrapping around some cyclonic flow and moisture.

What is good is that all the ensemble guidance (EPS/GEFS/GEPS) all show the Aleutian ridge rebuilding into the Bering Strait....so this isn't just one model ensemble showing it. We just need to keep an eye on the timing....if it keeps getting pushed back, then that would be trouble. If not, then we're probably going to have a nice period IMHO in mid-December.

We actually had the ice storm that week....then a brief torch after the ice storm before things went crazy for a few days 12/19-12/21

Yeah model gudiance has punted very early December for a few days now....we're gonna get a full torch for a few days there. But they are pretty adamant about rebuilding the Aleutian ridging into the WPO region by about Dec 7-9 or so. That should set the stage for some cold air bleeding down into northern CONUS and get some winter wx threats.

Looked like great times. Really bummed I had to bail on this one at the last second but couldn’t attend in good conscience being under the weather. I’ll def try and make the next one.

Yes. It’s looking like we could go full-torch for a few days in early December as the pattern shuffles. But we’ll see. If the NAO hangs a little tougher then the mild air would be blunted. Longer range guidance has been fairly volatile so confidence is low. That Aleutian ridge building up has been pretty consistent though. It’s just a long ways out so the timing isn’t going to be exact.

Everyone woke up this morning in my house under the weather. Normally I’d still come but I can’t in good faith...esp with the holiday just a few days away. Real bummer. Was looking forward to this one too. I’ll def try make next one.

Here's the EPS....you can see how the longwave pattern is pretty decent synoptically for a threat....you obviously need the details to work out, but the larger pieces are there..... You have your -NAO forcing the PV lobe under it into 50/50 low position while you have the main trough axis still back in the center of the CONUS and a nice PNA ridge to help amplify anything diving into that trough. Still a long shot but it's at least a compelling setup.
