That map I posted was the run-to-run change between September and October Euro seasonal.  The actual snowfall anomaly map is above and that shows AN in that location.

Looks about the same for me....about 15" below average seems reasonable. No complaints.

is roni going to lower the amount of latent heat that gets released into the climate system and trapped by carbon dioxide? is roni going to keep an eastward displaced north pacific low from flooding the continent with maritime airmasses all winter?

No to the first, but as far as as the second....not the RONI itself, but the disconnect that it represents may to an extent...and that doesn't necessarily mean colder in the east, either.

RONI is not meant to be used for the absolute intensity of this event. It’s more about gradients and storm tracks. With something this historic, it’s the absolute temperatures and water vapor increase that matter which is better reflected by ONI.

 

They why did the 2023 El Niño have a very meager GOA low presence despite a peak ONI of 2.0?
