El Nino who?

ERA5 record highest 500mb height over the CONUS is 6027 gpm (21 Aug 2023)

Now you've done it. Just wait for all those 246hr Gfs snowstorm maps this winter from us weenies.

Will it show the lowest DM ever recorded in US?

One regional caveat: 1977 was not warm at all in western Pennsylvania. It technically ranks as Pittsburgh’s 2nd-coldest summer, though several older downtown-era summers would likely have been colder under today’s airport siting/elevation. It was also the 7th-coldest at Erie.

That blistering July heat somehow largely skipped over this part of the region. Pittsburgh topped out at just 91°F, and Erie only reached 90°F all summer.

Thats crazy how it skipped over Pittsburgh. Detroit hit 102 and NYC 104.

The month had 14 days 90+ at DTW & 11 days at NYC

Strongest Niño on record with no precedence along with other competing factors and even some lingering niña-like effects. Wouldn’t be confident at all in making calls for the upcoming winter, especially at this juncture. Only confidence is that it’ll likely be very warm at times, and very statistically unlikely to be as cold as last winter in the East (even without taking ENSO into account).

Give me a spring like 1977 next year please. Still remains the warmest on record in my city, even beating out 2012 (and by far the warmest May). Kinda doesn’t really make sense either as it was a complete outlier in an era that was dominated by cold seasons in general (not just winter). Wonder what led to that happening.

I don't think a Winter -EPO El Nino is impossible. Further north it's more random than the mid-latitudes and the historical analog composite is probably biased to +epo (same with +ao and +nao of super Nino's). The warmth is definitely winning the battles in 2026 so far, however.

As I said, idk what happened at PIT but July 1977 had some brutal heat. However summers with brutal heat, regardless of the winter, are not uncommon in this area with our extreme seasons. But I do think spring 1977 gets lost in the shuffle. That was a very impressive and fast change from one of the coldest winters on record to one of the warmest springs.
