SEATTLE, Wash. – After a string of crisp, sunny fall days, Seattle and much of western Washington are bracing for a soggy turn as steady rain and clouds move in by late Thursday. The return of Pacific moisture will bring several days of wet conditions and cooler air, affecting commutes and outdoor plans through the weekend.
According to the National Weather Service in Seattle, a frontal system arriving Thursday night will deliver widespread rain and occasional breezes across King, Snohomish, and Pierce Counties. Rain chances reach 70% Thursday night and continue into Friday, with showers likely persisting through Saturday. Drivers along I-5, I-90, and SR-520 should expect slick pavement, reduced visibility, and longer travel times during peak commute hours.
Forecasters say rainfall totals could reach a half inch in the Seattle metro area and higher in the Cascade foothills. Winds remain manageable—generally under 15 mph—but localized gusts may accompany heavier rain bands. Residents planning fall events or pumpkin patch visits should prepare for muddy fields and pack rain gear for Friday and Saturday outings.
Sunday may bring brief clearing with lighter showers before another weak front slides in early next week. Temperatures will stay seasonable, with highs near 60°F and lows in the upper 40s.
While this stretch marks a typical mid-October weather shift, it’s a reminder that the Pacific Northwest’s wet season is back. Keep umbrellas handy—Seattle’s classic fall rain is here to stay through the weekend.
