PORTLAND, Ore. – Streetlights glint on damp pavement this morning as clouds creep in from the coast, signaling the next wave of Pacific moisture ready to soak the Willamette Valley. The quiet early hours won’t last long — by Thursday morning, steady rain and low clouds will settle over the metro area, making for a wet, gray stretch into the weekend.
According to the National Weather Service in Portland, light showers may develop today, but the main event arrives Thursday. Expect highs near 62°F with rain chances climbing to 90 percent by mid-morning. Winds will stay modest from the east at 5–10 mph, though breezy pockets may develop near the Columbia Gorge. Commuters should plan for slower travel, reduced visibility, and slick roads, especially during peak drive times.
By Friday, the pattern remains locked in — more steady rain and highs near 56°F, with an additional quarter inch or more of precipitation possible. While flooding is not expected, storm drains could clog with late-fall leaves, creating ponding on streets.
The weekend stays damp, with scattered showers Saturday and lingering clouds through Sunday. Highs dip slightly into the upper 50s, keeping the air mild but soggy. Early holiday travelers on I-5 and I-84 should allow extra time, particularly during heavier rainfall windows late Friday and Saturday morning.
Looking ahead, models hint at a brief dry break early next week before another system lines up just ahead of Thanksgiving — potentially the season’s strongest so far, with a cooler air mass and early winter feel by late November.
For now, it’s classic Portland November weather: gray skies, puddled streets, and that familiar rhythm of rain on rooftops.
