Portland, Oregon – Rain and a growing snow risk could impact Oregon Feb. 18-22, with cooler temperatures increasing low-elevation mix potential.
According to the National Weather Service 6-10 Day Outlook issued Thursday, Feb. 12, precipitation across Oregon is leaning above normal, with a 60-70% probability of wetter-than-average conditions during the Feb. 18-22 period. At the same time, temperatures are favored to trend below normal statewide.
Western Oregon, including Portland, Salem and Eugene, is expected to see periods of steady rain. However, with cooler air in place, snow levels could lower, raising the potential for mixed precipitation in valley communities, particularly during overnight hours.
The Cascades and higher elevations, including Santiam Pass and Government Camp, may see accumulating snowfall during the period. Eastern Oregon, including Bend and Pendleton, could also experience rain changing to snow if temperatures drop sufficiently.
The combination of above-normal precipitation probabilities and below-normal temperatures raises the risk of travel impacts, especially across mountain passes and higher terrain.
For commuters and college students returning after President’s Day week, fluctuating rain and snow could create slick conditions along Interstate 5, Interstate 84 and U.S. Highway 97, particularly during early morning hours.
The National Weather Service notes that 6-10 day outlooks reflect probability trends rather than exact storm totals or snowfall amounts. Residents are encouraged to monitor updated forecasts for refined timing, snow levels and accumulation estimates as the period approaches.
