Can someone say +AO? (For the 3rd warm season in a row, since the Solar Max)

[Stormchaserchuck1]

May be one of the stronger -PNA's on record in the long range, near the 19-20th

I think he is fairly close to Erie PA.

Same with Erie. And NYC for that matter. 1990s winters were warmer than 2000s or 2010s winters. The globe may have warmed in that timeframe but winters in the Lakes/Northeast were colder the next 2 decades after the 1990s. So any parallels to the 1997-98 nino I certainly wont be worried about a verbatim weather scenario with temps a degree or 2 warmer, thats not how the weather works.

Modelology vs meteorology. 

Where exactly is the cold air coming from if it’s all above normal north of Tennessee? It has to travel from somewhere on the way down right? Cold air can’t come from the pacific at California’s latitude. Which would mean at minimum, near or slightly below normal temps north of TN as it travels down? 

Yeah. i don’t buy wall to wall torch up here either. Maybe it’s 80/20, 70/30 or whatever. But the main reason that it’s blue in the South while dark red over the Great lakes is due to the uniformity of the airmass. 40s is well above normal for the Grest Lakes, but below normal for Louisiana. 

 

 

This is a good point. But even then, its not steady temps across the board. Its still colder in the mean in the north than the south. 

Which means blues in the south arent necessarily great for snow, but reds in the north arent prohibitive of snow either.

It seems to be warming near the oceans, on the East coast and West coast, but not as much in the Midwest, where it's flat.

I remember global predictions in the 90s had a +PDO/El Nino pattern projected for decades forward, but it has not happened that way. Maybe some of the EC warmth is associated with +AMO decadal.

Yea, a  -5 departure for the winter in a place like Atlanta  and southern apps probably implies some much below normal periods in there that if timed up with a nino-style stj can give them their freak snows.   Meanwhile, during those same periods we're cold but watching the juice slide under us.     Likewise, when a place like Columbus or Detroit sees a +5 departure for the winter in a nino, chances are that the cold periods are dry and the warm is wet.     

But like i mentioned in an earlier post, super ninos can definitely pack a surprise or two.

The scenario you describe (dry during the cold periods) was the big problem in 1982-83 here. I haven't looked up Colombus but in Detroit, still plenty of snow chances. Ironically in 1997-98 Feb was the really bad month here (the rest of winter was ok, including a snowy mid nov to mid dec) but Cincinnati got buried in Feb. All varies. 2015-16 finished just a bit below avg snow wise at Detroit but above avg snow a bit further north near @roardog.

The latest June update from the ECMWF has the ONI plumes Nino 3.4 average around +3.6 and the RONI near +3.0.

@LakePaste25 @donsutherland1 Not only does it show the strongest El Niño in history, it shows it being severely east-based/East Pacific like 1997 was. And a new downwelling Kelvin wave has begun to form in response to the big WWB we are seeing:

Euro seasonal only goes out thru December, but looks pretty similar to Cfs2 vs Cansips weather-wise. Very wet along the east coast. I'll take it with my inland location at 600'asl.

Here comes the constructive interference boost from a budding +IOD

Very impressive progression of model forecasts over the last several months. Now we are getting past the spring predictability barrier. So this most recent forecast update incorporates the big increase in upper ocean heat and continuing WWBs.

We can probably assume that the W pac warm pool will finally slosh east if those model output verify. You don’t get a +4C ONI Nino without it doing so.

Sitting near/at record highs now.

Let this be a lesson that the state and path dependency are more important than generally given credit for. Arguments about the spring barrier tended to discount this by default and also discount that these models have to parameterize certain calculations that end up biasing them *cold* on big honking tail events like this.

What happens when you get 1997 and 1972-like wind stress patterns with 2026 OHC/SSTs? We're about to find out.

 Regarding 1+2 less 3.4 per the table link below, 1982-3 fall/winter monthly peak was +1.1. This is based on Nov, which had 1+2 at +3.0 vs 3.4’s +1.9. 1997-8 peak differential was way up at +2.1 (also in Nov)! This is based on 1+2’s +4.5 vs 3.4’s +2.4. But the Euro per Ben’s quoted charts above has a mere only ~+0.7 for 2026-7’s peak monthly 1+2 less 3.4, which is in Sept with 1+2 then ~+3.8 vs 3.4’s ~+3.1! 

  So, the Euro is actually forecasting 26-7 to have a somewhat weaker 1+2 less 3.4 than 82-3 and MUCH weaker than 97-8. So per this measure, it’s forecasting a less E based 26-7 than 82-2 and MUCH less E based than 97-8.

It’s still going to be east-based

Edit: @GaWx By “severely” I mean warmest anomalies centered in region 1+2

Agreed. I didn’t say 26-7 wasn’t looking E based. I’m saying it doesn’t look as E based as 1982-3 and not anywhere close to (not even in the ballpark) as E based as 1997-8.

 You posted earlier today this:

“Not only does it show the strongest El Niño in history, it shows it being severely east-based/East Pacific like 1997 was.”

 This (“severely east-based/EP like 1997”) is not true when you compare the regions, which is how E based/C based/Modoki are defined.

i've skimmed through the first 10ish pages of this thread and a lot of you should be embarrassed

Winter storms in the South outside of the mountains are for the most part somewhat freaky events. Thus, due to the low frequency, our snowiest or iciest winters are often from mainly just one major (or series of) winter storms at most. Examples: late Jan of 1940, Feb of 1952, mid Feb of 1958, 12/31/1963, 2/9-10/1973, 3/1-2/1980, 3/24/1983, late Jan of 1987, 1/7-8/1988, mid Jan of 1992, the ice storm of late Jan 2005, and Dec of 2018. All of these were during El Niño and these were enough to make them wintry.

 So, El Nino’s on average produce for wintry precip despite often being mainly from just one storm on the right track (usually Gulf to off SE Coast) at the right time (when cold enough air to the N/NW being tapped into enough).

There is no question there is some type of correlation too, at least for places like AL/GA/MS/SC for the frequency to be higher during the cold AMO periods.  That does not seem to be as much a factor for TN/NC/AR/OK/TX.  But there is a higher peak, even in El Nino winters for those other 4 states in the 70s/80s and even during the more neutral or weaker warmer AMO period of the 40s/50s.  I don't know if that is purely that colder outbreaks are more common then or perhaps/phasing amplified systems that cut north of them are less likely.
