Thats the opposite of the expected el niño pattern.
Not a scientist. George Monbiot wrote about this. The new paper explores the impacts on crop production when meanders in the jet stream (Rossby waves) become stuck. Stuck patterns cause extreme weather. To put it crudely, if you live in the northern hemisphere and a kink in the jet stream (the band of strong winds a few miles above the Earth’s surface at mid-latitudes) is stuck to the south of you, your weather is likely to be cold and wet. If it’s stuck to the north of you, you’re likely to suffer escalating heat and drought.
Oh interesting, please do explain! I thought El Niño meant warmer and wetter weather for parts of NA
"During winter, El Nino leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North."

So wet north and dry south is not the average el niño pattern. Partly because el niño just started.
Ah interesting, thanks for sharing!
