Northwest Oregon Weather: Heavy Rain Returns Friday Night as Colder Air Approaches
PORTLAND, OR — The calm, cloudy start to Thursday across northwest Oregon won’t last long. By Friday night, a Pacific weather system will push inland, bringing heavy rain and gusty winds that will remind residents that November weather has officially arrived.
Rain Returns Friday Night
According to the National Weather Service in Portland, rain chances will climb to 70% by Friday evening and reach near 100% overnight, marking the first widespread rainfall in several days. Clouds will steadily thicken through the day as highs reach around 59°F, with south winds increasing slightly by nightfall.
Saturday: Wet Morning Commute
Rainfall totals could reach a quarter to half an inch by Saturday morning, with the heaviest showers before midday. Commuters traveling along I-5 and I-84 should anticipate slick roads and slower traffic, especially during the morning rush. As the front moves east, skies may partially clear by afternoon, though cooler air will linger.
Cooler and Breezy Sunday
Behind the front, Sunday will feel noticeably cooler, with highs in the mid-50s under partly cloudy skies. Light showers may linger across higher elevations, while the Willamette Valley begins drying out again. The breezy, crisp air will make it feel more like early November across the region.
Looking Ahead: Early Snow for the Cascades
Forecasters are monitoring a colder, more active weather pattern developing between November 8 and 15, which could bring the first snow of the season to Cascade passes, including Government Camp and Santiam Pass. Drivers planning mountain trips later next week should prepare for changing road conditions as temperatures continue to drop.
Fall’s Familiar Rhythm Returns
While Portlanders enjoy one last quiet day before the system arrives, the return of gray skies and steady rainfall signals that the Pacific Northwest’s signature fall pattern is back in full swing. It’s time once again for umbrellas, rain jackets, and warm coffee as the region transitions toward its wetter, colder months.
