No, May-June-July-Aug NAO was -0.75 per month, that comes out to -0.07/month for DJFM, or DJFM total of -0.28, based on 75 years. Weak correlation, but generally those 4 months negative then Oct pos is an interesting point for more winter -nao tendency.

May, June, Aug, Sept NAO total was -3.00.. -0.75/mo. 3/4 months negative. I think the overall correlation from -0.75 MJJA to DJFM is -0.07/8 lol.
-
It looks like May-Aug NAO was -0.75/month and if October ends up +.. that is a formula for a more -NAO Winter. Plus since 2012 90N May-Sept SLP has reverse for the Winter every time, and it was strong neg anomaly this Summer.

Yeah, October is the only month of the year that has an opposite correlation to DJFM NAO. I don't know if that's true given 250+ years of examples though.

I was 15, keeping a weather journal. Only year I ever did one. Picked one hell of a year for that huh! I was looking back and there was snow 4x in October, but it could have been flurries, or even just flakes -
Looks slightly negative overall.. with seasonal models. I just don't know that I think we are in a -NAO time right now

You got it with those correlation maps.. lack of a SE trough accentuates SE Canada ridge, or extends it south. The issue I think is - what is the Pacific pattern in that circumstance? It may favor a ridge NE of Japan or west-based -PNA with the NPH area off the West coast (most impacted region of east-based Nino) having a negative anomaly. I don't think the EPO and WPO are big parts of the ENSO/PDO, a little more random further north than what we are discussing. Negative EPO could come to our rescue this Winter but that index is the hardest to predict seasonally.

EPS with a >5940dm ridge south of the Aleutian islands at Hr 360 It's completely backed of the <-250dm at D10.. now models have like -150dm max and the pattern only lasts 3-4 days

Locally. I just had 3 consecutive nights in the 40s. No major heatwaves late Summer for the 3rd consecutive year. -

Nothing too unusual -
2026 Atlantic Hurricane Season
Stormchaserchuck1 replied to Stormchaserchuck1's topic in Tropical Headquarters
Well, 8 named storms and it's still September.. not bad. Shear in the Atlantic has been record high this season. I think the old days of 9NS/yr average, pre-1995, may be done. -
Daily PDO has been tanking.. it's near -2 right now

Under. Late Summer to September has been pretty cool.
