Northern Europe really warms up. 2 years ago, we hit 80* on the border of AK/Arctic Circle in late September, to cap off the Summer, so I wouldn't be surprised if there isn't some of that energy lingering. Maybe even into October.
^They must have changed the CDC reanaylsis plots. I had thought Nov-Dec 2018,2019 had the coldest 10mb ever since 1948. and that 2020 carried the trend, the last 3 years Nov-Dec, 10mb was record coldest on record.
We actually have >+0.0 waters in the central subsurface ENSO zone, which is the most favored area 0.90_0.75, this could lead us to some mean EC troughing in the future.
