Seattle, WA – Western Washington drivers should enjoy Thursday’s sunshine, because rain and slick roads return to Seattle by Friday night. The evening commute on Interstate 5 could become slow and hazardous as scattered showers spread across King County into the weekend.
According to the National Weather Service in Seattle, Thursday will stay mostly sunny with highs near 82 degrees. Winds remain light but shift northwest by afternoon. By late Friday, however, rain chances increase to 30 percent, climbing into the weekend with greater coverage. Saturday and Sunday both bring a steady chance of rain with highs in the mid-70s, signaling the start of fall-like conditions across Puget Sound.
Those with outdoor plans should prepare for wet weather by Friday night. Football games, festivals, and outdoor dining may face interruptions as showers roll in. DOT crews urge drivers to watch for slick spots, especially on bridges and ramps along I-5 and SR 520 where early-season rainfall often causes reduced traction.
While rainfall totals appear light, the timing could impact travel and weekend events. Residents are encouraged to keep rain gear handy and allow extra drive time through Monday morning.
The rain pattern lingers into early next week, with highs dropping into the low 70s. Cooler mornings and cloudy skies mark a shift away from recent late-summer warmth.
Showers may not be heavy, but they bring the first real taste of fall for the Seattle metro. Weather alerts remain possible as systems strengthen later in September.
