2026-2027 Super El Nino

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. 

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.

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.

^Vs the 61-90 average seems a little weird. 

You have to use the 1961-1990 base period or earlier which was in effect for the 1997-1998 super El Niño to directly compare the actual temperatures during 2023-2024.

Using a more recent 1991-2020 period will show smaller departures for 2023-2024.

The warmest CONUS winter rankings below are based on an even older base period starting in 1895. 

The 2023-2024 super El Niño event was the #1 warmest CONUS winter since 1895. The 2015-2016 super El Niño was the #3 warmest winter. While the 1997-1998 super El Niño was the 9th warmest CONUS winter.

Fargo's nearly +18° departure in February 2024 was undoubtedly boosted by the very strong Nino, but that wasn't the whole story.

Given the elevated global baseline and increased frequency of extreme warm anomalies, seeing a month like that this upcoming winter somewhere in the lower 48 wouldn't be too surprising. Not to mention the strength of this Nino, which is unprecedented. Things could potentially get out of hand, but I’m ready for it.

You might be but I'm not sure your phone or keyboard is since you only show up when it's warm.

This decade has been consistently warm so far. 2020, 2021, 2023, and 2024 (the warmest year on record) all rank among the ten warmest years for my city. This year has generally followed the same overall warm pattern, with January being the only month to post a meaningful negative temp departure (spring was top ten warmest as well). Based on the trend, the rest of the year will likely remain warmer than average as well. I'm not sure why this seems to bother you so much. 

The reason I rarely bother posting here anymore is because this board is packed with people who are complete denialists, so detached from reality that they dismiss years of temperature and snowfall trends whenever those trends don't match what they want to believe. Instead of looking at the evidence, they default to denial and personal attacks. It's not worth wasting time arguing with people who have no interest in an honest discussion, which is why I mainly use Discord now.

these weirdos think you're using it for some hidden agenda or whatever. That's an unbelievably paranoid line of thinking tbh, like, borderline schizo.

The exact opposite. I posted earlier that I liked the fact the Cansips faded the Niño west over the winter. He didn't quote me because that the way he operates.

An incredibly bold prediction to make in this day and age. A warm climate lends itself to warmer than normal temperatures? Tell us more.

Actually. Strong ninos often have cool months in the Fall. And we've already had several cool months this year, so no, i dont think every month the rest of the year will be warmer than avg.

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.

snowman made the stronger claim that +qbo, +enso decembers are a slam dunk always warmer than normal REGARDLESS OF STRENGTH (his exact words go read it). 1997/2004 are weakly +qbo. He's wrong.

Pretty good cold air correlation in Octobers in El Nino's historically:

Counter point is PDO also has a high correlation in October - negative being opposite of map below

Speaking of cansips. Its July 1st update maintains a cold look centered in the Great Lakes despite the nino strength. January is the coldest month relative to average. It warmed some in December.

Thanks Nostradamous

Not sure it's as sure as that. Everyone is jumping on like that 5/5 were warm in some skewed logic of Super being a different entity from Weak. I think -SLP in the warm season that we have going now 60-90N supports more Winter -AO. There is a global temperature jump happening I think and that could bring Winter warmer just about everywhere, but I don't it's as ENSO-related as people think.

The Canadian run is actually pretty cold most of the US in the winter. The look is -WPO ish.

We haven't really had a big El Nino with a -WPO. The El Ninos starting in 2023, 2019, 2018, 2015, 2006, 2002, 1997, 1987, 1986, 1982, 1972, 1968, 1965, 1957, 1951 are neutral/positive WPO net. The El Ninos starting 2014, 2009, 2004, 1994, 1991, 1977, 1976, 1969, 1963, 1958, 1953 are neutral/negative. 1982 was +WPO early, -WPO late winter (Dec v Feb) but mostly positive.

2009 is the strongest -WPO El Nino DJF, but even then its driven by a strongly negative -WPO in December.

For the stronger El Ninos (1957-58, 1965-66, 1972-73, 1982-83, 1991-92, 1997-98, 2015-16, 2023-24), the -WPO months are: Dec 2009, Feb 1992, Feb 1983, Feb 1958.

A lot of La Ninas in the South/Southwest are predominantly warm with sharp, brief cold shots - think all the recent snow down to the Gulf Coast, Texas in Feb 2021, etc. I'd expect a similar type of thing this year, but for the Northern US - predominantly warm with sharp, brief cold shots. The southern US should see mostly 'weak' cold but with brief sharp warm ups.

 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. 1997 is neutral QBO, not +QBO. So, it doesn’t need to be considered.

If the monthlies still say cold when get to the fall, then that's the time to start paying attention. I know strong and super el ninos usually mean warm winters, but if the monthlies are still showing a cold signal for winter in the fall, then you know something is up.
