The difference though is that last year the confluence was caused by a monster ridge where the PV is on that run...still confluence but in different ways.

Quebec is the new Siberia this time while they were torching last year.

Its true its totally differnt up there this year as no cold was to be found, But the end result could be the same here

Some of the more affluent people on the board should start their own airline. Call it Weenie Air, but have trans-continental flights to Asia so they can sample the atmosphere over the Pacific.

All true, until one gets to "NE NNE". CAR is 22" below avg for this point in the season, has only 7" on the ground, and is still +5F for Jan despite the recent cold wx. Vim Toot's description of conditions in potatoland, on the NNE thread, is classic.

Wasted it there.

Not much readership for that snow-beggared part of the world this year these years.

I think Scott's onto something with the normal Euro and what'll be the normal NAM bias in the SW. The pattern this year is so repetitive - as bad as it was good for the M A last year...can probably lock up 6-12+ already...no matter what happens it'll probably work out...front end dump, two part system, three parts system, inverted trough, who knows doesnt seem to matter.

--

FWIW here's the recent 120 hour. Not bad but it was north. Inside of 120 it didn't bounch all that much aside of 72 hours where it flunked out for some reason. Just informational...but I lean south if we were gambling.

Careful though. The Euro was definitely a bit too far NW, but it was also a little too fast, so that will add a latitudinal error when you look at verification, that's not representative of the track error.

Not sure if it was posted, but Crazy Uncle was a bit less amped than the Euro...probably a good snow hit for SNE and CNE taken verbatim.

Either way.. I really don't think we can discount these two trends with this storm...

1. This storm will be NW of the model consensus at. 36-72 hours out

Until I see a break in that I think we have to take those into consideration with this storm

2. This storm will be stronger than the models depict it at 36-72 hours out

And as a result the Mid Atlantic winter last year is our winter this year,

The difference though is that last year the confluence was caused by a monster ridge where the PV is on that run...still confluence but in different ways.

Quebec is the new Siberia this time while they were torching last year.

Looks like brutal subsidence over MHT no matter the scenario right now. Looks good for 6-12" CON north and 6-12" ASH south. Probably flurries in Manchvegas.
