SEATTLE, WA – A gray dawn greets Seattle this Monday morning, with the air cool, damp, and heavy with that familiar autumn stillness before the next rain. The Emerald City’s brief dry spell won’t last long — Pacific moisture is already lining up offshore, preparing to return by Tuesday and linger through much of midweek.
According to the National Weather Service in Seattle, light rain will begin to develop Tuesday afternoon as a Pacific front sweeps into western Washington. By Tuesday night, showers become widespread, with steady rain expected through early Wednesday. Winds shift east-southeast, gusting 20 to 25 mph along the coast and through the Strait. Rainfall totals could reach up to half an inch across Puget Sound by Wednesday morning, with heavier bands possible north toward Everett and Bellingham.
Commuters should expect slower travel on I-5 and wet conditions through Wednesday morning. Clouds will dominate, though brief breaks may appear mid-afternoon before another weak system brushes the region late Thursday. Temperatures stay consistent — highs near 55°F, lows around 45°F — keeping it comfortably cool but far from winter chill.
By Friday, skies begin to brighten as high pressure builds in, setting up a calmer, drier pattern for the Halloween weekend. Trick-or-treaters can look forward to mild, partly cloudy conditions Friday evening — a welcome pause between storms.
Long-range models hint at more Pacific moisture next week, though cooler air could tag along, suggesting early hints of a chilly November ahead.
