Seattle, Washington – A late-January arctic cold front is expected to push into Washington, bringing a colder and more unsettled pattern with increasing chances for snow, particularly across interior lowlands and mountain passes as January ends and early February begins.
According to the National Weather Service Climate Prediction Center, the Jan. 24–Feb. 6 period favors below-normal temperatures across the Pacific Northwest, with precipitation chances increasing as colder air spills south and interacts with Pacific moisture. This setup raises the potential for snow not only in the Cascades, but also in parts of western Washington during the coldest periods.
Western Washington, including Seattle, Tacoma, Everett, and Olympia, could see one or more opportunities for lowland snow or rain changing to snow if colder air arrives quickly. Even light accumulations could lead to slick conditions on I-5, I-405, and key arterial roads during overnight and early morning hours.
The Cascades and mountain passes, including Snoqualmie, Stevens, and White Pass, are expected to see more consistent snowfall, increasing the risk for difficult travel and possible pass restrictions. Eastern Washington, including Spokane and the Palouse, will likely experience colder temperatures with periodic snow chances, though totals remain uncertain.
Statewide impacts include icy roads, increased heating demand, and potential travel disruptions, especially in higher terrain. Residents are encouraged to prepare for colder conditions, monitor pass reports, and stay alert for updates as storm chances increase toward the end of the month.
Below-normal temperatures are expected to persist into early February, with additional advisories or alerts possible as the pattern becomes clearer.
