Still gets pretty warm aloft... thicknesses support mixed precip way north of the H85 line like Dendrite has been mentioning.

Can't even count how many times we've seen the GFS way too warm 48 hours out in these setups and then slowly trend colder.

Congrats Dendrite on the 18z gfs...looks like all snow. Maybe even 1" down to the pike on the front end.

He may not see a 6 year stretch like this in that area, again in his life....that spot has just been unable to lose since the 2006-07 season...unreal.

Crushed in the OCT KU and now this....I essentially missed both. lol

I can't believe that he only avgs like 10" more than I do...its been like 30" over that 6 year span.

Yeah the difference here and why I'm not yet concerned about this completely whiffing to the south (though anything seems possible with the models these days) is that normally we see blocking or a -NAO upstream that would allow for this to continue going south. Sure the high pressure may trend a bit stronger, but the NAO is still positive and the airmass is not all that cold to begin with. I could still see this bumping north again with no blocking upsteam. Watch Montreal get the jackpot, lol.

One of the perks of living up here is that I am 25 miles north and 500 feet higher than Dendrite. I never have to ask how much IMB? I get personalized forecasts just reading the thread. Love the model trend. Unfortunetly having 15 people driving up from SNE on Thur AM but should be fine by then. Kind of nervous with power issues with a pasting snow but at least the leaves are now 100% down.

South trend ain't done yet folks.. As HPC said yesterday..with the strength and position of that high there was no way this was shooting NW like it did the last 2 days.. Soon we will be back at the Euro solution from late last week of a snowfall for SNE

ALB now has WSW up for all of S.VT. Almost there.

The high has actually trended a couple mb stronger int he past 24 hours which is probably why we are seeing the rare colder trend on a SWFE. Reminds me of a weaker version of 12/16/07 in that regard...that high trended stronger as we got closer and we ended up getting blasted by the time the event was upon us.

80-90% of the time the trend is opposite with little to no blocking. Def good for those in CNE where it might mean the difference between a sloppy inch and 5-7".

that high and low combo was amazing. you know how they saw you want a 'fresh' arctic airmass in place rather than a stale one. well that was a protype. i was -23C low that day and my high was -13C. that is pretty much unheard of to get those kind of temps to dig in over quebec and to have a storm barrel into the cold dome.

fabulous event.

Maybe they will get taken out back to the woodshed '64-'65 style this year.

LOL Mike is the "QPF Queen"...

It's a beautiful dance he does. He congratulates everyone else for being the jackpot on the 00z JMA. When it looks more likely that GC will get in on the action he openly frets about the diminishing QPF (Messenger does his best to fan these flames by constant posting about the SE trend and convective feedback.) Then as the precip breaks out to our SW he fixates on the radar looking too spotty or wrong trajectory. Then come the excited posts between he and I as the heavy snow sets up over us. After houirs of SN+ obs he falls asleep and then awakens to make astonished posts about the new 24" that has fallen. It really is a wonderful thing and I look forward to it repeating over and over again this Winter.

Probably not. I've really been lucking out with deform bands on the SNE storms and then front end thumps from SWFEs.

The 18z GFS is alright here, but I changeover on this run. It's warmer aloft versus 12z although it's a little faster too. I'd probably push warning criteria before mixing with RA/PL.

Possibly a white Thanksgiving? Do tell. lol

Sounds like oct 2011
