Portland, Oregon – Oregon is expected to remain firmly entrenched in an unusually warm pattern during the first full week of February, with high confidence that temperatures will stay well above seasonal averages statewide.
According to the National Weather Service and NOAA’s Climate Prediction Center, there is an 80 to 90 percent probability that temperatures from Tuesday through the following Monday will run above normal across Oregon. Daytime highs in western Oregon, including Portland, Salem, and Eugene, are expected to reach the upper 40s to mid-50s, several degrees warmer than typical early February conditions. Overnight lows should remain mild, often staying above freezing in lower elevations.
Central and eastern Oregon will also trend warmer than normal, though colder nights will persist in high desert and mountain valleys. Even so, the signal strongly favors fewer hard freezes and less persistent cold compared to a typical midwinter pattern.
Precipitation chances appear limited overall, especially west of the Cascades, reducing the likelihood of low-elevation snow. Mountain snow levels are expected to remain elevated, which could impact snowpack accumulation and contribute to gradual snowmelt at lower elevations.
Travel along major routes such as I-5, I-84, and U.S. 97 should remain largely unaffected by winter weather, though drivers crossing mountain passes should still watch for overnight refreezing. Residents may notice early signs of springlike conditions, but officials caution that winter is far from over. The warm pattern is expected to persist through the week, with additional updates possible if conditions shift later in February.
