Yeah ... and it not just the AO.  All the indexes are flagging a warm abrupt end to winter ... This is the agglomerate index mode on Mar 7:

+AO/+EPO/+NAO/-PNA         Mmm, yeeeeah, that's a pretty quick end.  I mean, maybe in another era, imagined or distantly in the past, the behaviors of the total atmosphere would argue for exceptions to the rule that implies - a big warm one.   But nowadays ?

Folks need to get real about where we are circumstantially at a global scale, and just how enabling this has been over the last 6 or so weeks

Here, and Japan ...  are the only two places on the entire planet, where civility reigns or doesn't, that has experienced a January that was "cold" relative to climate, and probably extending into these first 10 days of February.

Where do folks think this winter would be without that very insular layout above?  Experienced hobbyists and mets know why this was the case ( above) and it was related to the NE Pacific dominating the circulation mode during that 45+ days.   Oscillating between -EPO cold loading into N/A and/or highly compressed low wave height +PNAs

Should this index spread confirm, +AO/+EPO/+NAO/-PNA  , out there, doing so in that world above, at a time of year deep into the solar transition, during a La NIna footprint that correlates to warmer than normal springs... during CC... anything else we can pile on?   I mean, geez  

 

 

Lol..you said this on MLK day too…for two weeks later.  Maybe this time? Maybe not.

Mean sucks ass.

-"What does she look like, Johnny"

-"She has a beautiful heart that warms a room"

That’s prob where you want it at D8. Otherwise it will end up in Ottawa the way this year has gone. :lol:

mm no.  Not in this context.  That was regarding a single model run of the GFS, and I was discussing why those "kind" of looks shouldn't be tossed because of the broader correlations in play.  If anything, below is a the primitive attempt to materialize that idea, so it offers support to it.

The teleconnectors now, are in aggregate, completely abandoning any cold signaling.  It is entirely fair to say that is a first, if perhaps primitive, in deterministic method to demonstrate the matter; within which, that is unfortunately what you don't like.  Too bad. 

If you want to quibble with the notion that nothing is absolute - okay.  That's true everywhere in nature at all times, at all scales.  But one that is connected to objective reality understands the importance of probability, and how reality is constructed out of very high degrees of to anticipate - it's like one of the things that separates humans from other apes.  We're all supposed to remove that native, gift of evolution and faculty of higher order intelligence, because you think the future cannot be presupposed.  Not going to happen.   EVER.

Lol, not on the weeklies…maybe someone else does. I do have a precip anomaly map

Weeklies are cold, below normal right through March ( well below normal Feb 17-27). Maintain east coast trough west coast ridge through first week of March.  Looks dry first week of March , other than that very active.

Yeah... I only "like" the 20th because as I've been pointing out using a lot of tl;dr's and some time wasting annotations ... the flow is relaxing while entering a +PNA. 

However, as I've also pointed out... this is not the first time this last 45+ days I've seen the guidance aggregate attempt this lessening compression - but what happens is an insidiously slow adding of gradient in time, such that we're not aware ...we just end up sped up to hell and back in the same quagmire.

Back to earth re the 17th ... it's a little frustrating because there are canonical reasons to argue that track being farther S-E... Not even a ton, but just not so enraged like the Euro.  

I also noticed the 12z GFS is outright modeling a nasty tuck early Monday.   I still think we have a lot of low level model error potential from this range, with that warm intrusion - all cynicism and snark aside.

You know my feeling with respect to potential this period ....I'm just letting off some steam. Certainly not tossing anything.

Here's where we are at ending February 10th. I started working on these Monday so they don't include last nights light snow.

Nice, thanks.  FWIW I have 30" here very near where you show 21" just SW of Quabbin.

I was waiting for someone to utter that obligatory cliche...don't forget, this season has been an equal opportinity sodomizer in every direction.

How about this:

The mean is useful only for the general longwave pattern, useless for storm location.  For storm location you have to look at the clusters.  Otherwise, you are falling for "The Golden Mean Fallacy".
