2026-2027 Super El Nino

Which is more likely? ONI at 3.5, or 3.5 pages without mention of snow in the Northeast. I know what I'd bet on.

July 2015 was actually very much dead on the long-term temp correlation for Nino 1.2, 3, 3.4, 4, etc. This year has been less so month to date.

The pattern right now for July looks a lot like the 2023-24 winter - very warm NE 1/4 of the US, a bit cool or near average West & South. But July 2023 itself was cold North Central.

The Modoki El Ninos that are cold in the East in winter tend to be cold in July in the East: 2004, 2009, 2014 were all cold in the East or Northeast for both.

Best indication that everything is "clicking" correctly for US El Nino impacts is the long-term precipitation tendency. We're not there yet. Amarillo-Boise zone is not behaving yet. Northeast and Florida should be much better too. 

 

The map (even accounting for Tropical Tidbits adjusting for global SSTs by global mean above average) for oceans looks very different to July 2023.

You can see on the maps four major differences to now if it isn't clear:

1) In 2023, you had hot water east of Mexico, cold water west of Mexico. That implied high pressure off the West Coast, and low pressure of the east coast. Absolute worst possible case for monsoon development. Followed the hottest June on record in Mexico, and coincided with the hottest July (and month) ever locally. in 2026, the warm water west of Mexico implies low pressure and the colder Gulf implies high pressure - nearly ideal pattern for moisture. Monsoon has been quite strong in Mexico since May and should pick up locally here too in the next week.

2) NE/SE Atlantic are night and day different - much colder now than 2023.

3) Coldest waters are relatively in the Atlantic now. Not the Pacific.

4) The SE Pacific (SW of South America) is much warmer, consistent maybe with steady weakening of the -PDO, just as the -PDO seems to be weakening somewhat in the NE Pacific. Still present though for both spots.

Im not going to play catch up since I have last been on here but here is TAO from May through July 4th, I'll be taking out May next update around mid month.

The difference in overall depth of the warm anomalies looks to be an artifact of the -PDO still being around. During the 2023-24 Nino this was centered around 130-140W. We also are lacking a significant negative anomaly region developing near the Dateline. I gotta ask the question though are we seeing Nino take on a new form with SSTs the way they are globally?

 The strong left-sidedness of the MJO continues:

Per The Long Paddock website, which hasn’t shown a new SOI daily since July 2nd:

 June/July SOI values have been subject to an incorrect data feed. The values will return after the data source has been replaced and values are recalculated.

100%. The 30C isotherm is already east of the dateline and the EURO seasonal started showing this happening last month, projecting that the 30C isotherm will push all the way to 120W by November, which would be an all time record. I absolutely believe it given the huge WWBs we’ve been seeing since April. This year, unlike 2015, we have a complete trade wind reversal with WWBs/westerlies and DWKWs pushing well east of the dateline with no resistance….that is going to keep pushing the 30C warm pool east. We didn’t see that in 2015, in fact, we actually saw EWBs and the trade winds fighting back even up to this point in time…this year, not even close. The surface from region 3.4 to region 3, to region 1+2 is warmer and the subsurface is warmer than 2015 with more substantial WWBs and DWKWs. Region 4 is actually cooling now, also unlike 2015. The TC/typhoon parade projected to begin this month in the WPAC and the EPAC and the MJO progression is only going to reinforce it (WWBs, DWKWs)


 

 

 

 

Wow:

The PDO continues to operate independently of El Nino. The more Niña-like pattern which resulted in record heat in the East caused the PDO to fall and the AMO to rise. This is a result of the strong mid-latitude ridges warming the ocean surface below.

The Atlantic City, NJ with the airport on the edge of the Pine Barrens just tied its all-time highest temperature. Most other years above 100° were La Ninas like 2011 or weaker El Niños or more neutral years.
