Portland Weather: Snow Showers Possible This Week
Portland and Vancouver metro areas are bracing for a chilly week with the potential for snow showers, particularly overnight and in the early mornings. Whereas significant accumulations are not expected in the lower elevations, a Winter Weather Advisory is in effect for the Coast Range and Cascades through Thursday night.
Current Conditions and Forecast
As of Tuesday, February 17, 2026, cloudy skies and cold rain are impacting the region. Temperatures are in the upper 30s, with little warming expected. Showers will continue into the late morning, with highs near 43°F. A rain and snow mix is possible as snow levels drop to between 500 and 750 feet by Tuesday [Koin].
Snow Risk and Potential Accumulation
The National Weather Service reports a 50 to 70 percent chance of at least a trace of snow by Thursday morning for the Portland and Vancouver metro area [Hoodline]. There is a 10 to 20 percent chance of a narrow band dropping 1 to 2 inches of snow Wednesday night into Thursday morning. Any wet pavement that refreezes could create icy patches, particularly on bridges, overpasses, and shaded ramps.
Winter Weather Advisory
A Winter Weather Advisory is currently in effect from 4 a.m. Monday through 4 a.m. Thursday for the Coast Range, Cascades, and Cascade foothills. These higher elevations could receive several inches of snow. Travelers heading to these areas should check pass and road reports and be prepared for reduced visibility and traction requirements [Hoodline].
Valley Forecast
Portland and the valley can expect potential freezing temperatures and snow showers each night and early morning. Scattered rain showers and/or a wintry mix are likely each afternoon. Dry weather is expected on Friday, with rain possible over the weekend [KGW].
Travel Considerations
Commuters should deliver themselves extra travel time, watch for ponding water in low spots, and be prepared for slick road conditions. Highways above 1,000 feet in the Coast Range are already covered in snow [KGW].
