Both Wet & Dry

Well, the long awaited turn into a wet period has taken place.  Looking forward through October, we see both wet & dry periods, with lowering snow levels, at times, in the mountain,.  Oh, and we see a Mug that needs refilling.  Get to it.

That cool Low pressure system, that has been ‘parked’ west of the WA/OR coast the past day or two, will finally nudge inland, continuing rain and showers, along with a possible thunderstorm, through today (the 10th) into the first half of the weekend.  Another Low will move in from the NW BC coast on Sunday, with even cooler temps, more rain, and lowering snow levels.  

By early Monday Oct 13 - Columbus Day - that Sunday Low will have worked its way down along the southern OR coast, setting up an outflow of chilly WINDS down the Fraser Gap, and to a lesser extent, the Columbia River Gorge.  (This will NOT be an Arctic Event as the ‘Yukon Dome’ of high pressure will be well above our ‘indicator' 1040 mb depth.)  Clearing, but notably chilly, most of the day Monday (upper 40s to low 50s).  Shutdown or not, Columbus Day is a recognized Federal holiday, so don’t expect everything to be open.  Grab a book if indoors; a sweater if outdoors that day.  

The rest of the Oct 13-17 week is charting as DRY and gradually warming - - temps could climb back into the upper 60s to low 70s by Fri.  Winds will diminish late Tue, so don’t be surprised to experience some foggy-bottoms later in the week.  California will turn WET and rather stormy as the PNW Low is modeled to drop farther south, wetting the Golden State; some localized flooding or mudslide issues could develop.  

Our next chance some precipitation arrives the weekend of Oct 18,19.  No strong storm is charted, just a cold front draping over the PNW, with most of the moisture falling over southern & eastern OR on Sunday.  Temps will cool down again, much like Columbus Day.

Week of Oct 20-24:  Trending mostly dry, with a glancing cold front passing mainly over BC mid-week.  Fall cool temps on tap.  Earlier solutions brought more rain into the entire region; we’ll see what verifies.  —> Possible STRONG WINDS across northern CA early that week, as a wet Low passes over Las Vegas.

Dry for the Oct 25,26 weekend, per current projections.
