2026-2027 Record-breaking El Nino

The upcoming east coast heatwave and the recent western snowfalls is a canonical la nina feature. Yet another sign we are not yet being influenced by + enso.

The present more Niña-like pattern is probably being enhanced by how much warmer the Indian Ocean through the Maritime Continent to around the Dateline is than all the other previous super El Niños at this time of year. So we get a westward extension of the forcing overlapping with the El Niño standing wave. 

Notice how the dates of the record warmth going back to March in the East coincided with the forcing moving from the Indian Ocean to the WPAC. Plus the interaction between the record SSTs in the Mid-latitudes could also be influencing the pattern. Even the state of the Arctic could be playing a role. 

The extent of the +30C pool is larger than 2023 at this time when we were having a much cooler El Nino-like pattern from the late spring into summer.

So we are getting a head start on the Niña-like influences which waited until closer to the winter in December 2015 and January 2024 to occur. 

+30 C warm pool expansion since the late 1990s during the late spring of developing super El Niños

GLAAM just dropped from record highs to slightly above normal. I think we're at risk of ruthlessly extrapolating some short term mean reverting variability here. It's definitely coupled to the atmosphere. Hell, there's a standing wave set up in the tropical Pacific already.

The entire warm pool is being discharged.

Not only is there not any significant trade resistance this time around (remember '15?), quite a bit of activity has been ongoing away from the equator in addition to being on it. Modeling has steadily been playing catchup since the start of the event as it gradually incorporates all of the additional accumulated wind stress and eckman transport. 

This will be a colossal east-based event and trying to short it or fade it or talk it down is a fool's game. Look I get it, I like snow too and very early on (Dec/Jan) I was hoping we'd get a moderate event with the indo-pacific warm pool still intact. But that ain't happening. Better off cheering for some exotically warm winter up north that forces some weirdly favorable wave breaks downstream and south. Or save your emotional capital for the backlash Nina period. These big Ninos do have a tendency to cause climate regime shifts, so it's not always a bad thing once the event clears.

Wrong! You’re an idiot. Delete your account

What part is wrong? December 1997 and 2004 were indeed +QBO, + ENSO, and below normal. 2018 near normal. Refute the claim. These are numbers not opinions. You can be warm biased without literally lying like you currently are.

Backlash nina period won't be good for some of us either so...emotional capital for the year (or two) after? Lol

Huh what are you talking about? December 1997, 2004, and 2018 were all +QBO, +ENSO and below or near normal in new england. Incredible that you can spread misinfo like this and get away without anyone calling you out.

He does this every year. He loves to bash anyone who disagrees with him.  Ignore him and post away.

Is canonical a popular word now ? I heard that all winter last year but it wasnt a normal la Nina winter.

I could be wrong, but I believe a strong El Nino is traditionally better compared to avg for Colorado than it is in the east. Plus of course, we know how Denver can rack up September and May snow with 70F in January .

While measurable snow is normal here in the Detroit area from November thru April, its a more traditional curve, with the snowiest month being January followed closely by February (each month over 12"), with both November and April each averaging just under 2". A common trend seen in strong El Ninos is well ABOVE avg snowfall in November, followed by below avg snow in December. Once you get to January results get more mixed.

Yeah, strong Ninos almost always deliver at least one 12"+ storm here. Most commonly late Oct-mid Dec and then Mar/Apr.

Our last backlash nina period had one great snow season (2010-11) and a 5-month torch from November-March (2011-12).

1997 was close to neutral

2004 was close to neutral

2018 was a modest +QBO. I'll give him that one. That was a meh December (and winter overall), not an all out blow torch, like the other 5 +QBO/el nino Decembers.

That’s what I’m banking on. As long as the ElNino from hell manages to slay the west pacific hot blob dragon,  I’ll gladly sacrifice next winter to appease the weather gods.

He said the fact that we’ve had 6 +QBO/El Nino Decembers since 1980 is a lie

+QBO Nino Decembers: 1982 (warm temps), 1987 (warm), 1994 (warm), 2006 (warm), 2015 (warm), and 2018 (normal).

I count 1997’s 0.78 as neutral QBO

2004’s +2.45 and falling is pretty neutral

 So, I agree on 6 Nino Dec +QBOs since 1980. And all but one were warm. 2018 was NN. Favors warmth in Dec for sure!

And 1997/2004 (neutral QBO) weren’t warm.

Edit: Dec of 1957 also had +QBO and was warm! But Dec of 1963 (moderate Nino) and Dec of 1969 (weak Nino) were cold despite +QBO.

**Edit 2: If we stick to just high end moderate/strong/super Nino fall/winter peak with +QBO Dec, Dec was warm in all 5: 1957, 1982, 87, 94, 2015.

Therefore, I think warm Dec is notably climo favored as of now.

This year was basically fine. Just need to keep it to a low simmer and slowly reconstitute the warm pool over time. Maybe throw in a cooler NATL spell that can reinforce trades and pop an actual CP Nino or two. We're at least very very likely to see some very strong Arctic warming into early winter '27-28 (response up there tends to lag lower latitudes quite a bit).

Which year between 10-11 or 11-12 had a very strong Arctic warming?

I don't understand how you have reached the conclusion that the mid Atlantic will not muster so much as a moderate event....Jesus, what is it with inability of the majority of this forum to accept any dialectical nuance.  It's either ALL or NOTHING. The reality is that the coastal plane has a decent shot of a major event this year and history dictates that.

I think csnavy was hoping for a moderate Nino earlier this year before it was obvious that there wasn’t going to be? Don’t think snowstorm is being inferred here. Nobody can say whether there will be one or not

Was referring to hoping for a moderate Nino event initially. Quickly became evident in March that wasn't going to be the case.

[Stormchaserchuck1]

The difference between Weak vs Moderate vs Strong vs Super Nino is the same. In weaker events, the ENSO signal is weaker so other things dominate more, more randomness. Caveat being that East vs West based event does make a difference.

@PhiEaglesfan712

Cold ENSO/Strong -QBO gave us a cold December last year too. 2021 was the exception, but it works in reverse too (cold ENSO/-QBO is cold). Even in Dec 2021 there was a >+300dm block in the N. Pacific. Move that 250 miles NE and it would have been cold. 

Of course the Nov Stratosphere warming last year was the reason.

We've definitely already peaked as far as the Pacific cold phase goes....likely pretty near neutral for the coming winter (slightly negative probably favored), but I still think it will be early next decade, around the solar min, when we truly switch into the new warm phase. Like a very big winter right after the solar min, as we begin the ascending phase.

I think the Arctic cold this warm season will serve as a catalyst to keep the PDO more negative in comparison to ENSO this year. It's a pattern. Still have July-Sept to go though, so it could change, but since the Solar Max it's been a pretty sustained Summer +AO pattern.

Oh, geez....so sorry. My bad.....yea, I held out some hope initially, but quickly became clear it was not to be.

That's not east based. I like the way warmest anomalies fade west.

This may surprise some people - Nino 4 is neutral in trend since mid-April

I think what it comes down to is it's easy to keep the heat out of the eastern regions if it's weaker, but def. agree on the bolded.

Low pressure over the N. Pacific favors east coast troughing though. Of course if the negative anomaly spills into the West coast like 82-83 and 97-98, that pushes everything east. +AO kind of dominated the pattern in 82-83 though. 

 

[bluewave]

The more west based super El Niño in 2023-2024 had an even warmer winter than the east based 1997-1998 super El Niño.

So exactly where the warmest SSTs end up with 2026-2027 that is forecast to be significantly stronger than both of those may not really matter that much.

Plus I also don’t think the timing of how quickly the SSTs drop by the later portion of winter into spring will make much of a difference considering how record breaking the peak with this one will be.
