Upon inception of -dAAMt mid-month, you would expect any ridge to retrograde offshore fairly quickly. Very skeptical of any prolonged western heat with this wave cycle, could be quite awhile until a lower frequency +TNH tendency becomes apparent.
Experienced 100+ degrees five days this century in the area. Three from 2021. The other was 2009, and there was another 100 burger in some Eastside areas a couple years after that (2015?).
I would be willing to bet something liike it will legit will happen again, possibly more than one more time, very tough to bet against it now. What probably won't happen again is a 1950 type winter, that should have happened again before the 3 day 2021 inferno, but it didn't. Just my opinion, that is all.
