Oregon – The sound of steady rainfall fills the early morning air across Portland as the city settles into another gray, soaked start. Pavement glistens under misty streetlights, and traffic splashes along I-5 — a preview of what’s shaping up to be a wet and blustery December weekend across northwest Oregon.
Rain will continue through the day and into the weekend as a series of Pacific fronts push inland. According to the National Weather Service, showers will be heavy at times with gusts up to 25 mph and highs near 56°F. The Hydrologic Outlook remains in effect, warning of prolonged rainfall and rising rivers through next week as an atmospheric river develops. Though widespread flooding isn’t expected yet, low-lying and urban areas could see ponding and minor drainage issues by late Sunday.
Saturday won’t bring much relief — rain chances stay near 100%, with steady showers and highs around 54°F. Expect reduced visibility and slick roads on major routes including I-84, US-26, and I-205, especially during peak travel hours.
By Sunday, the wet pattern strengthens again. Models show widespread rainfall returning with another inch or more possible through late evening. Winds ease slightly, but the soil saturation increases runoff potential into early Monday.
A mild start to next week continues the soggy theme, with highs near 57°F and daily rain chances holding above 80%. Long-range models keep Oregon in an active pattern as December’s second week approaches, hinting at possible colder systems down the line.
