Ref the question in yesterday's comments....unfortunately no...the first 10 and maybe 15 days of September look dry with high pressure off the coast. While we could see isolated mountain showers from weak upper level lows off the coast. None of the models show any shift that looks like the first storm of fall.
Today a low pressure trough and frontal system are moving through western Canada and the Pacific Northwest. We may see a few high from this system but for the most part today will be sunny with slightly cooler temperatures. Gusty southwest to northwest winds will occur this afternoon over the higher elevations.
Sunday the high pressure off the coast gets stronger and things start warming back up. Sunday through Tuesday with will be sunny. Monday will be the hottest day with temperatures 6 to 12 degrees above normal. Gusty north winds will occur on Monday.
Wednesday through the weekend a weak upper level low pressure area will be over the Pacific Northwest and along the coast. (see map below) This will cool temperatures back to near normal and may trigger some afternoon cumulus clouds Thursday and Friday.
