Pattern Change.


SpartyOn

Recommended Posts

gfs has the 0 850 line over northern AL at 192 hr. Euro has it over GRR.

no doubt gfs will begin to collapse to the euro and the zonal pac flow forecasts will win out. A pattern change? yep, for Canada and northern tier states. What year was it when it stayed brutal cold over Canada throughout all of January with record warmth over the Conus? It was '01 or '02 I believe and it was the year that JB claimed January would be the coldest on record and it turned out one of the warmest on record. He said he nailed the 500mb forecast but it didn't work out at the surface :lol:

2001-2002 was when he thought January would be brutal and it was a bust pretty much everywhere, including Canada

From part of the Area Forecast Discussion out of the NWS in Northern Indiana at 424pm est today...

.LONG TERM...

WEDNESDAY THROUGH MONDAY

LONG LATITUDINAL TROUGH WILL SUPPORT SIG HEIGHT FALLS INTO THE

GREAT LAKES MID NEXT WEEK...WITH ANOTHER ROUND OF STRONG CAA PER AN

ADVECTING MODIFIED ARCTIC AIRMASS. H85 TEMPS WILL FALL NEARLY 20

DEGREES C...WITH PERTURBED NW FLOW OFFERING SNOW SHOWERS...ESP AS

INVERSION HEIGHTS RISE...AND LAKE EFFECT SNOWS ACTIVATE. LONG

TRAJECTORY FLOW WITH MODERATE LAKE INDUCED INSTABILITY AND POSSIBLE

SUPERIOR AGGREGATE AFFECTS WILL SUPPORT THE THREAT FOR HEAVY LAKE

EFFECT SNOW OVER SOME OF THE NW ZONES. LARGE SCALE FLOW WILL THEN

SLOWLY MODIFY AS PAC ORIGIN ZONAL DOWNSLOPE FLOW PUSHES BACK INTO

THE REGION BY THE LATE THIS WEEKEND...WITH TEMPS EXPECTED TO WARM

SAT THROUGH SUNDAY. THE POTENTIAL FOR WESTERN ATLANTIC FLOW BLOCKING

WITH GULF OF ALASKA REX BLOCK RIDGING /CONTINUALLY ADVERTISED IN THE

ECMWF/ MAY SUPPORT A SIG COLD SPELL OUTSIDE THE PERIOD BY MID-LATE

NEXT WEEK. HOWEVER...GIVEN THE PREVALENT PAC FLOW REGIME THIS

WINTER...CONFIDENCE IN THIS SOLUTION REMAINS LOW ATTM...GIVEN THE

CONTINUED LACK OF GREENLAND POSITIVE HEIGHT ANOMALIES AND ASSOCIATED

NEGATIVE NAO.

Yep, I remember his Vodka Cold, Hawaiian traffic cop low pressures, etc... This winter is looking more and more like a repeat of that wretched winter. Hopefully '12-'13 will be a major turnaround like '02-'03.

Holy crap!! Those were some amazing pics!

And you cant even use the old saying "the rich get richer". Its beyond that. Valdez AS IT IS is the snowiest city in the U.S. with an avg of 326". And they are seeing record snow for THEM. Meanwhile...the continental 48 so far has seen below to much below normal snowfall nearly across the board, from the snowless Sierra to green New England. Luckily it looks like some white is in store for the north in a few days!

so we go zonal with a tight gradient. Can't wait to see more modified PAC air.

Like stated before the pattern change is gonna come in installments.

IF the pattern change comes in installments, itd be the best case scenario for our area imo. A tight gradient could be golden for our area with a possible train of L's/clippers. Once, or if, the "vodka" cold gets locked in, count on lots of supression where we can hopefully snag a clipper or two that doesnt track well south of us. Of course, this would be fine for me if we have a nice snowcover courtesy of the tight gradient pattern.

It looks like early April where I live. Lots of bare spots with dirty, hard snow piles.

Although it would be kinda cool to make it an entire year without getting a 1" snowfall(Feb 6th), it's looking like that streak will be difficult to continue much longer. If the models are correct about the upcoming pattern change, there should be a series of at least weak disturbances riding the fast w/wnw flow across the region. Any or all of them could drop 1+ inches of snow.

That's what I'm concerned about.. Sometime the other shoe has to drop, hopefully it won't be springtime. How much would it suck to not only have a crappy winter, but a slow severe weather season. Talk about a double whammy!

Ha, I doubt we have a cold Spring...that's just me trolling the warmwantistas/trolls of the forum. Maybe the other shoe will drop by next December...we can only hope. :lol:

GEFS have us torching by next Monday and beyond. Starting to think this so called pattern change is bunk. :lol:

It will probably be better/more sustained roughly north of 40N at least for the next week or 2. That brief (hopefully) warmup early next week may be enough to wipe out a lot of the snow though.

I haven't seen the 12z GEFS yet, but the 0z and especially the 6z runs kept all the cold air in western Canada/Pac NW...with some intrusion into the northern Plains. Otherwise, it's solidly above normal for everyone else (Monday and beyond on average). Still can get a winter/snow event or two I suppose, but it's not exactly pretty. At the end of the run, it's full retrogression and we go back to what we've been seeing for the past couple of weeks.

I can snag my 2-3 Thursday and still be in play for sub 9"....it's called having your cake and eating it too.

I'm not sure if you saw my post about the winter of 1936-37 in the general Jan thread. I can totally see that happening. Imagine you and Joe popping the champagne on a record least snowy winter and along comes a late March 3-4"-er that spoils the party. :lol:

Anyone seen the most recent NAO observations?

Yeah, a brief dip to neutral/negative and then back to positive. Of course the ensembles have been pretty bad with their forecasting of the NAO. That period from Nov 16 to Dec 16 on the bottom panel is embarrassing.

Would be nice. Personally I would rather we bust hard on this winter and get it over and out of here. We are due for a **** winter..we really are..forget, forgive and move on. Lets face it bro. We technically lost 1/3rd or more of our Winter to a torch. Spring Robins and tulips will be here before you know u it. Also a fresh severe weather season:-)!! Tiger bats will be a cracking in no time.
