It’s a mostly cloudy start to our Sunday across the Portland/Vancouver metro area. Clouds will gradually clear out by the late morning, giving way to a nice afternoon with highs in the mid 70s. Clouds should return this evening, keeping temperatures on the mild side of things tonight.
Monday and Tuesday will feature a good amount of cloud cover, but some sunbreaks as well. High temperatures should range between the low to mid 70s across the Willamette Valley. Overall, we should stay mainly dry through Tuesday and possibly early Wednesday morning.
Forecast models have been in agreement for several days now on changes arriving Wednesday. A plume of moisture (AKA an atmospheric river) will collide with a cold front digging into the Northwest. This will lead to a wet day on Wednesday and high temps dipping back into the 60s. There’s a bit of concern about steady moderate/heavy rain falling on our local burn scars. This could lead to additional debris flows in those locations. Showery weather continues Thursday, and possibly Friday/Saturday as well. Drier weather should prevail by Sunday.
Have a great day, and enjoy the fresh air!
