Weathafella official winter forecast...supercedes all prior guesses


weathafella

Recommended Posts

Analog years:

1950-51, 1964-65, 1968-69, 1970-71, 1988-89, 1999-00, 2000-01, 2001-02, 2008-09. Thankfully, the weakest of the list are 1999-00 and 2001-02. I base this on late Sept early October SSTA of the Pacific AND the Atlantic as well as other factors. ENSO sometimes doesn't add up well but so be it.

Here is the winter composite (dec-march) using those years.

Winters overall are average.

So I'm playing 52 pickup and see what I can come up with.

I think there are some ominous signs for snow lovers right now. Snow cover and ice are lagging particularly in Eurasia. While we may well be in a long term negative NAO regime and most assuredly a negative PDO period, NAO may not cooperate as much this year given some early signs.

Many have touted the gradient pattern and that fits most La Nina seasons. However the strength of this Nina is going to trump 2008-09 so while that is probably the best analog year, I need to be careful.

So my forecast is very different than most and since I'm not predicting heavy snow outside of the usual spots, I expect to be pilloried. I don't give a f u c k.

I believe December will begin very mild and the above normal regime will dominate most of the month. Cold periods in the 2nd and last week may give some hope but any snow will be quickly erased by the above normal pattern.

January should turn cold and hold cold most of the month and I suspect for most of us, 75% of our seasonal snow will occur then. February should turn mild again until the final week and March actually may be a decent winter month.

Temperatures:

DEC: +4

JAN: -2

FEB: +2

MAR: -4

Snow...major climo centers, Kevin, Steve, Pete, Will, Ray, major climo centers:

BOS: 31 inches

PVD: 28 inches

BDL: 36 inches

ORH: 56 inches

GINX: 33 inches

GC: 340 inches

RAY: 53 inches

REV: 42 inches..

Phil on the Cape: 19 inches

Rindge: 75 inches

Hubb Dave: 49 inches

Northern New England: Decent but not spectacular year.

Sorry friends, I hope I'm wrong but I suspect I won't be. October has disappointed in so many ways. We're fooked. Squirrels are not fat and neither is the cryosphere.

We had some dry periods in those years...both cold/dry and warm/dry.

I should correlate autumns. 1988-89 was cold and bone dry. The late 90s and of course 2001-02 as well. We have the sun on our side this year but I don't see alot of help from it this year but that's what is preventing snow totals in my mind being way lower.

It's hard to believe we'll see a long-term dry pattern, given what's been going on lately.
