Portland, Oregon – Oregon is expected to close out January and move into early February under a warmer-than-normal and relatively dry weather pattern, with above-average temperatures spreading statewide and limited opportunities for rain or mountain snow.
According to the National Weather Service Climate Prediction Center, the Jan. 24–Feb. 6 outlook favors above-normal temperatures across much of the Pacific Northwest, including Oregon, with below-normal precipitation probabilities. A persistent ridge of high pressure is expected to keep stronger Pacific systems aimed north into British Columbia, limiting moisture across the region.
Western Oregon, including Portland, Salem, and Eugene, is expected to see milder daytime highs with fewer rain days than typical for late January. While occasional clouds may pass through, no prolonged wet periods are indicated, helping keep travel conditions favorable along I-5 and Highway 99.
Central and eastern Oregon, including Bend, Redmond, and Pendleton, will also trend warmer than average with dry conditions dominating. Overnight temperatures will still drop below freezing in high desert locations, but daytime warming should be noticeable. In the Cascades, snowfall chances remain limited, slowing short-term snowpack growth at higher elevations.
The primary impacts statewide will be tied to the lack of precipitation, including reduced mountain snow accumulation and increased awareness of dry fuels during breezy periods. Outdoor activities and travel are expected to see minimal weather disruptions.
Above-average temperatures are expected to persist into early February. While the pattern remains quiet for now, updated outlooks may be issued if Pacific storm tracks begin shifting south later in the month.
