Oregon – Pavement still looks dry early, but the calm won’t last. Clouds thicken quickly, and by later today, rain begins tapping on roofs and pooling along curbs across the Portland metro.
According to the National Weather Service, rain develops by late afternoon and becomes more widespread tonight, continuing through Wednesday. Early temperatures sit near 36°F, cold enough to keep a winter edge in the air, but warm enough to avoid icing for now. Highs today reach the upper 40s before steady rain settles in.
Tonight and Wednesday bring the most consistent rainfall. Roads across Portland, Beaverton, Gresham, and Vancouver will turn slick, especially during the morning commute. Expect reduced visibility, standing water in low spots, and slower travel along I-5, I-84, and Highway 26. While rainfall totals remain modest, wet pavement combined with lingering winter grime increases stopping distances.
By Wednesday night, rain continues with temperatures staying in the mid to upper 40s. That prevents freezing but keeps conditions damp and chilly. Thursday trends similar, with rain likely through the day and highs in the low 50s. To be fair, this pattern favors nuisance impacts rather than severe hazards, but accidents often spike during long wet stretches.
Friday stays unsettled with scattered rain showers and highs near 55°F. Sidewalks, trails, and neighborhood streets remain slick. Plan extra time for errands and school pickups. Keep headlights on in rain and avoid sudden braking on busy arterials.
Looking ahead, NOAA’s 6–10 day outlook shows near-normal precipitation and above-normal temperatures into early February. That suggests rain continues to dominate rather than snow, even as winter lingers.
For now, grab rain gear, slow down on wet roads, and expect soggy commutes through the workweek. How wet did your drive feel this morning around Portland?
