Sea level anomalies vs 1997….wow Sea level heights…this is a monster: -

2026-2027 Super El Nino

Not ready to say it will never reverse. Maybe 10 more years of -PDO and I’ll start having those thoughts. The only thing that’s certain is the that the planet will be warmer. When it comes to everything else, weather can always feel like it’s in a permanent state until one day it isn’t anymore. -

I am speaking in the present....I agree there is a chance that this one can become a more prominent hemispheric driver, but we aren't there yet. This is all I meant on Sunday on when I Said El Nino still had work to do. -

2026-2027 Super El Nino

I don’t know if this can be claimed with certainty yet. It’s also important not to use too much recency bias when it’s likely going to be the most powerful event on record. I’d be more skeptical if this was like 23-24. Even beyond 15-16 this event is in a league of its own. But, we will also have our own variations of winter forecasts this Fall and we can always look back on them. -

I feel like if the PDO doesn't reverse, especially with how big of an el nino we are expected to have, we are pretty much in a permanent -PDO. We haven't had a +PDO winter now since 2015-16, which was more than a decade ago, and is unprecedented. Even in previous predominant -PDO periods, we got a +PDO in there somewhere. Also, if we don't reach 175 ACE this year, it would be sixth straight year that we don't reach the threshold. Here is a list of longest periods with no hyperactive (175+ ACE) seasons: 1. 1962-1994 (33 seasons) 2. 1894-1925 (32 seasons) 3. 1934-1949 (16 seasons) 4. 2006-2016 (11 seasons) 5. 1927-1932 (6 seasons) [2026 would tie this streak, which began in 2021] The thirteen hyperactive (175+ ACE) seasons are: 1893 1926 1933 1950 1955 1961 1995 1998 2003 2004 2005 2017 2020 -
2026-2027 Super El Nino

The influence of ENSO, especially warm ENSO, is more geographically restricted now and more largely relegated to the tropics, regardless of it's intensity. Powerful events are more influential....in the tropics. However, the mid latitudes are now more dictated by these marine heat waves and expanding ridges. I get what Adam is saying....this El Nino is a powerhouse, but it's just that it's more the scope of Andrew rather than Katrina. -
Beats the usual smells in that area

That might also explain why the models have backed off on what was nascent potential for cap busters along the front Wednesday...

Yeah, I have been saying this for a while now. Once past the spring predictability barrier, the models like the Euro do a great job with ENSO SST plumes forecast. So the record breaking nature of this event isn’t in doubt. We can see the strong coupling with the atmospheric patterns in the tropics and the very high shear in the Caribbean. But the subtropics or mid-latitudes continue to do their own thing. It’s a very strong -PDO pattern north of the tropics rights now. If this mid-latitude pattern can continue to have some influence going into the winter, then the Aleutian low could split or end up in a different location than usual. It’s also possible the typical strong Nino ridge south of Hudson Bay could at least at times get displaced further to the south over the Eastern CONUS. This could mean that the heavily precipitation zones with the STJ may vary from the 1997-1998 locations like we saw in 2015-2016 and 2023-2024. -
Certainly possible the smoke could have an impact on surface temperatures but with an elevated mixed-layer moving in and dewpoints climbing instability shouldn't be an issue. Also, in terms of the MCS...this may sort of set the boundary for where the corridor of highest severe weather potential exists. This will probably leave behind some residual outflow boundaries and also have to watch out for a strong differential heating zone which may become established. But once the MCS passes things should begin destabilizing quickly. Big question I think is going to be do storms pop during the afternoon (like HRRR has). These would be more discrete/supercell and pose the greatest risk for very large hail and tornadoes
