Winter 2026-2027. Historic Potential

Upper 40s tonight. I think it will be cold enough in the Winter. Would be really surprised if we do a scenario like 97-98. Last 2 years we had early cold periods in September and they were both cooler Winters. Would have to be an unfavorable index pattern like +EPO if the Winter goes wrong, only mildly connected to ENSO. 

Who hacked your account Chuck? You're making me nervous with your positivity.

you are all free to tell me why the most historically unfavorable enso state is going to be better this time

Is a record-breaking east-based La Nina the most historically favorable state for cold?

I think the global warming skew is significantly helping your case

An actual low in the N. Pacific is not bad for NE, US cold - wavelengths never get that long on average. It's more in the Upper Midwest. There has been a slight historical tint of anomalous troughs in the arctic in the historical east-based Nino dataset 48-25, more examples than a few is more random there. And El Nino does tend to warm the Stratosphere, so over like 200 years of examples you would have more -ao.

2 things can be true. A winter could be warm and rainy, and it could also have a blizzard. 

This is the thing forky is deliberately forgetting. 2023-24 averaged 0.7F warmer (DCA) compared to 97-98, and had 8" of snowfall. 15-16 was only 0.5F colder than 97-98. Likewise, 72-73 was 3F colder than that winter, but was also a shutout. A Super Nino can overwhelm the base state with torcherrific airmasses for 90% of the winter, but it very evidently does its best to load the deck in the few intervals that temperatures are remotely seasonable.

Eh...I see what you're saying, but ENSO doesn't operate in a vacuum. I get the sample size limitation, but we also need to consider that 3/4 Super El Ninos have occurred during the descending portion of the solar cycle, which is pretty hostile towards sustained high latitude blocking. I don't think that connection between descending solar and super El Nino is a coincidence, either.

this is stronger and further east than 1997. why is anyone remotely hopeful

I think your thought process is intentionally linear here.....you know damn well how chaotic snowfall is and the bar that year is pretty damn low...I'll take the over.

You don't think +EPO has been historically favored during super El Nino with a huge GOA low?? The seasonal mean will be +EPO, but I think we can have some fleeting periods of cross polar flow.

We won the toss in 2016 so I'm predicting we lose it this time, lol We only win the super niño toss every other time!

There will undoubtedly be less MC influence this season relative to 2016.
