Seattle, WA – A gray morning sky hangs low over Puget Sound, still quiet for now — the kind of calm that never lasts long this time of year. Clouds are already thickening over western Washington, setting up the next stretch of wet weather expected to move in this weekend.
According to the National Weather Service in Seattle, today stays mostly dry and cool, with highs near 51°F and light north winds. Clouds build through Friday night ahead of a weak front that may bring a few light showers Saturday, mostly north of the city. By Sunday night, that pattern strengthens — with a 30% to 40% chance of measurable rain developing into Monday.
The heaviest rainfall is expected Monday into Tuesday morning, potentially affecting post-Thanksgiving travelers on I-5, I-90, and U.S. 2. Roads could turn slick, especially during early commutes, as temperatures hover in the mid-40s. While no flooding or snow is forecast for the lowlands, mountain passes could see wet snow and fog, signaling a transition toward early December winter travel conditions across the Cascades.
Next week looks cooler but unsettled, with daytime highs near 47°F and a few showers lingering midweek.
Plan extra travel time if you’re heading back from the holiday — and keep rain gear close as winter’s rhythm returns to the Northwest.
