One helluva EPO download going on with this 12z GFS run - wow.

Scott - yeah, agreed. that product seems a bit amped, so why I added that I wasn't sure if were normalized somehow. We'll see, but the operational means for D8-10 off both primaries has a pretty potent looking -EPO ridge, and that does actually relate well with AB Pac/-WPO/ at least some present of MJO. I also agree that the the MJO is [probably] less correlative at this time of year due to all kind of noise damping things, but when superimposed over recurvature might just give it a kick, being the thinking there - and subsequently registered down stream effect.

Time will tell.. .

I agree with that EPO ridge. I guess the question is how strong will it get, and how will the -PNA try to fight it off. That's the gradient pattern look we've been describing. The GFS obviously is quick to bring cooler air our way, but the EC and even Canadian are saying not so fast. But, the GEFS have won a few battle so maybe we'll see a couple of shots?

And to be clear, this is after early next week when we mentioned we will probably cool down later in the week. The question is just how much.

Oh yeah...we're talking late middle range onward at the earliest. My deal is the attempt to assess the last 10 days of the month

...if not to prevent a bad-karma snow in that time frame with all my might ...

You gotta wonder ... if at some point in the last 2 million years of eastern North American history, just once did a full bird hurricane get sucked up into a bitter cold core full latitude hammer - just once. It's hinted at every year it seems. The big nor'easter of Dec' 2003, the CMC model sniffed that out at D9 as a just such a fusion of insane polarity. I think it stem-wound the bomb on down some 950mb and change, with snow on the western semi-circle.

Push came to shove and while there was a TC, it stayed in the Caribbean then moved NE and out without getting involved with the westerlies like that.

I read some old articles on the 1804 storm in the stacks at Cornell back years ago. They had newspapers from Boston back to like 1790, lol. I don't know where they got them from.

At any rate, there was 1-2 feet of snow out this way from it and even more up into NH.

Let us guess ... no other snow fell through the rest of that year :arrowhead:

GEFS pretty chilly towards late next week.

It seems as if all of the operational models except the EURO have trended towards the more progressive GFS wrt to cutoff low later this week and also how the pattern evolves next week.

Scott do you think the recurving typhoons (or stalled) are having an effect on the models and why they are behaving erraticly?

Euro ensembles of a couple days ago seemed too aggressive in breaking down the huge Aleutian -EPO ridge...GEFS definitely keeping it around which would transition us to a shot of colder weather down the road once the -PNA relaxes a tad.

Seems as if lately the euro ensembles have been outdone by the GEFS

Perhaps the most extraordinary early-season snowstorm in New England history occurred on Oct. 9, 1804 when a hurricane roared ashore on Long Island, New York and then encountered an arctic air mass over southeastern Canada. The winds of the hurricane caused extensive structural damage from New York to Massachusetts (where the steeple of North Church in Boston was blown down). The rain turned to snow as far south as the Connecticut River Valley in Connecticut, where low elevation towns from here to the Canadian border received 4-6" of snow, and the higher terrain of Vermont up to three feet of accumulation. In Vermont, drifts buried fences and blocked roads. The Catskills of New York reported 12-18"; the Berkshires of Massachusetts received 24-30". Even coastal New Haven reported some snow (and 3.66" of rain). Reference: "Early American Winters: 1604-1820", by David M. Ludlum, American Meteorological Society, 1966, and "Early American Hurricanes, 1492-1870", by the same author
