A few years ago, it was breaking 127/128F in Death Valley for 4 days in a row in early June. All-time record is 134. With SW High getting stronger, something to watch out for.
+PNA/El Nino-transition really phased out today on models., -PDO-pattern for next 15 days. I think this will hold through the Winter, El Nino or not, and it could be something like 72-73. -PNA tendency, especially next Jan-Feb
Do you notice how the PNA/EPO and NAO are always dancing?
1) I see Winter pretty much over
2) the +PNA this Jan and Feb might give us a -PNA next Jan and Feb, but with -NAO or AO maybe
Usually you don't get new ENSO state (warm subsurface-now) -change impact the Winter pattern, Dec-Mar. Usually it's first felt in April. I guess 1988 is a counter example where we had more southern stream High pressures. The +PNA is from warm subsurface ENSO (greater 500mb correlation than surface, by alot). 1) The amount of "+PNA cold" we see in the east is capped by this "law".
