2026-2027 El Nino

[Stormchaserchuck1]

^CPC was putting out long range Winter outlooks that looked like that: warm in the SE, cooler in the NE. Then last month they updated with a full on El Nino composite for the Winter.

 The new Cansips has winter anomalies significantly colder in the NE than the SE:

 For all of the Ninos peaking at +1.5+, not a single one going back at least to 1895-6 had a colder NE than SE anomaly wise! Not even one!
 
 These are the winters: 2023-4, 2015-6, 2009-10, 2002-3, 1997-8, 1991-2, 1987-8, 1986-7, 1982-3, 1972-3, 1965-6, 1957-8, 1940-1, 1930-1, 1925-6, 1918-9, 1902-3, 1899-00, and 1896-7. That’s 19 winters, a nice sample size suggesting the CANSIPS E US winter temp. anomalies and a strong El Niño prog aren’t at all jibing with history.

 Here is the aggregate of those 19 winters:

 

Edit: Even going all of the way down to peaks of +1.0 yields the same result, no winter colder in NE than SE. That adds 13 more for a total sample size of 33!

I see it has some split forcing showing up with some lingering convection in the west pacific. Also appears to be more basin-wide. I agree - i think a +TNH outcome like that is probably overkill even if there’s split forcing.

Yea, I could buy some vestige of it remaining, but it's probably overdone.

@bluewaveLooks to me like the Pac jet was up to it's old tricks again in March, as the blocking for met winter abated and the MJO, albeit largely favorable, remained weak.

Oh no! That's the best site on the internet! Why the heck would they stop it?

It did well last year. I was skeptical it would end up that cold. Interesting to see how it does this year.

I’m looking for it to bust badly assuming El Niño verifies.

Last Summer the CANSIP had -5 anomalies around the Great Lakes and Midwest at 0.0 month (the 1st of the month). It verified +2-3 lol

What does it look like in the ENSO region?

Brings ENSO warm as far west as New Guinea lol

What Chuck said. It has a healthy strength Nino, probably nearing or exceeding +1.5 ONI. That doesn’t at all jibe with the La Ninaish temperature anomaly pattern it has for the US!
