ECMWF bottoms out in the mid to upper 70s in Seattle on Thursday... looks like low to mid 80s next weekend. Maybe upper 80s in Portland next weekend again.
Huge drop between Tuesday and Wednesday despite no low clouds at all until late Wednesday.
ECMWF delays marine layer along the coast and any push inland until Wednesday night. Haven't seen temps yet but assume Wednesday has to be cooler. Marine layer even makes it to Seattle for a few hours on Thursday morning. Another ridge builds in again after the trough passes to the north but it seems more reasonable with morning clouds along the coast and patchy inland each morning next weekend.
