Mid to late February Pattern Discussion...stormy or end of winter?

JB Tip and LL have cancelled winter at one time or another this month, Kev cancelled the second half of Feb and all of March back in Feb, game on.

 

 

 

What - don't group me with those guys.  

 

I spoke factually about the teleconnector spread, objectively, and that did not require "canceling" anything

Tip, the PNA has very little bearing on our temps by late February and actually has a positive correlation (albeit weakly) with our temps by March rather than inverse correlation, so I would pretty much ignore the PNA signal unless we are looking at temps down in the Mid-Atlantic or southeast U.S.

 

EPO signal weakens as well, but still important...NAO most important in late Feb. All of them though have dampened signals compared to mid-winter.

It's not the PNA that worries me ....  it's the COMBINATION of the PNA + EPO + (2-5 octanes of the MJO), that's the issue - I was clear. 

 

But, I agree the NAO being negative is interesting...

Yeah John I understand the intricacies of these teleconnections. I think what sort of opens my eyes, is an active branch of the jet to our south, and the propensity of a -NAO. The caveat might be temps...but this IMHO has the look of an active pattern. 

 

Maybe it will be an above average bowling season - word

Pretty active week on the models. This was the pattern and week I was referring to a couple weeks ago. LOL

Last half of Feb looks banging with plenty of S/W's though. I gave you guys my forecast through Feb.11 last Sunday. I will write a more indepth forecast and POP of the last 3 weeks on Monday or something. But it looks like Feb 11-13 will be another 5-10 degree warm up ahead of a S/W arriving the 14 or 15th with colder air behind it for Feb 15-17.

 

Strat. analogs are showing 4 storms in a week and a half period for the second half of Feb. I'm waiting for more GWO data though before I confirm and jump on the bandwagon for such an active pattern. Although this would jive with the thoughts of a snowy pattern for the Plains/upper MS valley and the NE still ending up with about normal snowfall while at the same time having above normal temps for the month....just plenty of opportunities to score while getting screwed on others.

 

Also like the high in the way at 140W. I think it will do a nice job of splitting this strong xt-RWT at 170W in to several pieces with pockets of energy slipping underneath and emerging as pulses along the southern jet that could possible end up phasing with their siblings that took the northern jet on the 21/22 time frame. Also marked out xt-RWT over Africa that I think will be a player come March 6/7 that matches up with a Mtn. torque event meaning colder air should be over the region. I think it could be a decent storm for someone.

No

Yes

 

TUESDAY INTO TUESDAY NIGHT...WHILE INITIALLY DRY AND QUIET...SOUTHERLY FLOW WILL ENHANCE AHEAD OFA STRONG LOW PRESSURE SYSTEM WELL NORTH AND WEST OF NEW ENGLAND. THEATTENDANT COLD FRONT WILL BE THE FOCUS FOR WET WX ALONG THE COASTSWITH POSSIBLE INTERIOR SNOWS. AS MENTIONED EARLIER...THE 14.0Z RUNSOF BOTH THE GFS AND ECMWF HAVE BECOME SIMILAR. WILL CONCEDE TO ABLEND OF THE TWO. STRONG SOUTHERLY FLOW AHEAD OF THE ATTENDANT COLDFRONT TO THE SYSTEM WILL LIKELY RESULT IN A ALL RAIN TO RAIN/SNOWMIX FOR THE S/E SHORES AND COASTAL PLAINS OF NEW ENGLAND...WITHBETTER CHANCES OF SNOW ACROSS THE INTERIOR /SEVERAL INCHES PSBL/.

as modeled right now, it's meh. could evolve into something better depending on how things shift around to our NE but it's mainly wet even for you on the 00z runs.

 

maybe one of these days you'll actually trust us instead of thinking we are 2nd rate to other mets who don't post here.

Why so nasty and defensive and jumping into a 1 way convo?

Lol. Not nasty or defensive at all.

Just saying - you never like / believe our take on things...always have to find other thoughts to dispute our posts. How come?
