Seattle, Washington – Low clouds blanket the city at dawn as a dim gray glow washes over wet sidewalks and the chill breeze carries the scent of Puget Sound. The early quiet feels heavy and expectant, signaling a shift toward a wetter pattern just as Thanksgiving travel begins surging across Western Washington.
According to the National Weather Service, a 30 percent chance of rain develops later today before a stronger system arrives Wednesday night. By Wednesday evening, increasing moisture pushes rain across the metro with a 30 percent chance near sunset and higher probabilities heading into the late-night hours. Commuters along I-5, Highway 99, and the West Seattle Bridge should prepare for slower travel, glossy pavement, and brief periods of reduced visibility as steadier showers form.
Today stays mostly cloudy with a high near the upper 40s, but this lull sets the stage for Wednesday’s wetter push. Models hint at a clear Winter Tease—no lowland snow yet, but the cool air, damp mornings, and strengthening Pacific flow all point toward early-season transitions. Travelers heading east toward Snoqualmie Pass should watch for a possible changeover to snow in higher elevations, even if the metro stays in rain.
Rain continues into Thursday morning with highs rising into the mid-50s. The early window may bring the slickest conditions, especially near the downtown corridors and the Ship Canal bridges. Conditions gradually improve Thursday afternoon as drier air moves in.
Friday’s rain likely returns by evening, kicking off a wetter stretch into the weekend. Saturday and Sunday remain rainy at times, giving Seattle a classic November feel as heavier Thanksgiving Week travel begins.
