Portland, Oregon – A colder and increasingly active weather pattern is expected to take hold across Oregon by Thursday, with temperatures dipping below seasonal averages and a higher likelihood of rain and mountain snow affecting travel and daily routines statewide.
According to the National Weather Service and NOAA’s Climate Prediction Center, the 8–14 day outlook from Friday through the middle of next week favors below-normal temperatures across much of Oregon. Daytime highs are expected to run several degrees below typical mid-February levels, keeping lowland areas cool while reinforcing snow potential in the Cascades and higher elevations.
Portland, Salem, Eugene, Corvallis, and much of western Oregon fall within the cooler-than-average signal, while central and eastern Oregon are also expected to remain colder than normal, particularly overnight. Morning lows near or below freezing could lead to slick spots on untreated roads, bridges, and shaded surfaces.
Precipitation probabilities are above average statewide during this period. Repeated systems are likely to bring frequent rain to western valleys and accumulating snow to the Cascades, including Santiam Pass, Willamette Pass, and Government Camp. The Oregon Department of Transportation warns that mountain travel could be slowed by snow-covered roads, reduced visibility, and potential chain requirements.
The colder, wetter pattern is expected to persist into the middle of next week. Residents are encouraged to monitor updated advisories and pass conditions, as additional alerts may be issued with each incoming system and shifting snow levels.
