Yeah, there are years when you just sniff out a warm December. 2015, 2021, and 2023 were pretty obvious. The Weather Channel had these predicted months in advance. This year looks like that way as well. 2026 would make it the 4 warmest Decembers ever in 12 years.

Nowhere in that post did I say as warm as 2015, I said “the strongest warm December signal since 2015”

I'm sure they'll be winter weather sometime between late November and late March. Just expect much of the winter to have temps above normal. Probably lots of rain.

A good indication will be late October and early November, that's when the torch began leading to that insane Decmber month..Lets see if we see that in a few weeks

2021 and 2023 were warm in October and cool in November before torching in December. Then again, those were -QBO years, with 2021 being a la nina. 2023 was a strong nino.

If I remember correctly, 2015 had a very warm late August and September. October was the odd cool month in the bunch.

Like anything, when warmth dominates a pattern, it doesnt mean there will be no cold shots. And its impossible to pinpoint when they will be. I will be surprised if there isnt a spell of cold/snow in the Great Lakes in November.

Another big time WWB is in progress currently. This time pushing east of the dateline. First chart are the actual zonal winds.
