2025-2026 ENSO

[raindancewx]

From what I can see, no relevance for Dec, Feb, Mar for East Coast temps where it snows / where nor'easters are important.

For the alarmists out there you can make the case whatever importance that was there in January is also rapidly diminishing - almost all of the East Coast in the 10+ inch avg snowfall climo zone is now in the borderline irrelevant correlation zone. The deeper blue zone is way south of where it is on the longer term map...

March has a high -PNA/-NAO and +PNA/+NAO correlation.. wedges the SE ridge to near neutral. This is definitely a pattern though.. the lack of benchmark storms is because 80% of our Winter months have been -PNA since 2018

But there is a strong, strong correlation with US Temps and the SOI pre-1948. I suggest you check it out. I was only calling what I saw as SE ridge/NW trough -PNA, without looking at the North Pacific H5 (no data before 1948). It is possible the total composite of the 1948-2020 dataset is not big enough, if that is possible. Late 1800s - 1950, the SOI indicating a La Nina/El Nino was strongly correlated to Winter US Temperatures.
