Summer and winter don’t share any statistically significant correlations (certainly none tied to verifiable climate system dynamics).
Example, 1957 was a super niño onset summer w/ -PMM/-PDO and was a hot summer as well. Also had the solar max/+QBO in a similar stage of shear stress. That turned out to be a very solid winter.
Hmm if the Summer is verifying so warm something says the Winter won't perform. Unless the ridging max centers over the NAO domain - we've pretty much had 14 straight +NAO Winter's in the mean so let's see.
On the other side of the coin, today was my 8th 100+ day of the year. Second highest number I’ve ever recorded (behind 2012 which had 9).
In conjunction with the drought/convective whiffs this has been the worst buzzkill of a Niño onset summer imaginable. Unfathomably tragic. Winter had better perform.
