Portland, Oregon – A more active and wetter-than-normal weather pattern is expected to take hold across Oregon from Friday through early the following week, bringing increased chances for rain in the valleys and periods of snow in the Cascades and higher elevations.
According to the National Weather Service Climate Prediction Center, the 8 to 14-day outlook for Jan. 30 through Feb. 5 places Oregon among a small group of states favored for above-normal precipitation. While much of the central and eastern United States remains locked in a colder and drier pattern, the Pacific Northwest is positioned under a more active Pacific storm track.
Temperatures across western Oregon, including Portland, Salem, Eugene, and the central Willamette Valley, are expected to run near to slightly above seasonal averages. That setup favors rain rather than lowland snow for most communities, though chilly mornings and occasional cool days remain likely. East of the Cascades, including Bend, Redmond, and Klamath Falls, temperatures are expected to fluctuate closer to seasonal norms, with colder nights but less persistent cold than across the Plains and Midwest.
The main impact during this period will be precipitation. Repeated systems are expected to bring periods of rain to western Oregon, while the Cascades and higher terrain see accumulating snow. Snow levels may rise and fall with each system, leading to changing travel conditions over mountain passes such as Santiam, Willamette, and Government Camp along Highway 26. Eastern Oregon may see lighter precipitation overall, though occasional snow showers remain possible.
This wetter pattern contrasts with below-normal precipitation expected across much of the Midwest, Great Lakes, and East Coast. While no major flooding signal is currently indicated, saturated ground and renewed rises on rivers and streams are possible if systems arrive in quick succession.
Oregonians should prepare for a wetter stretch, plan ahead for mountain travel, and stay alert for updated advisories as individual storms approach. Additional outlook updates are expected as confidence in timing and impacts continues to improve.
