Seattle, Wash. – Streetlights glisten on damp pavement this early Tuesday as clouds thicken over Puget Sound — the kind of morning that signals another stretch of classic fall rain. Light showers will build through the day, followed by a steady push of moisture Tuesday night as a Pacific system moves ashore. Commuters along I-5 should expect wet conditions and slower travel both this morning and evening.
According to the National Weather Service in Seattle, rain becomes widespread Tuesday evening, with totals up to a tenth of an inch across King and Snohomish Counties. Winds stay light, but low clouds and drizzle may linger through Wednesday morning before skies begin to break. Highs climb into the upper 50s under spotty sun Wednesday afternoon — a short-lived break before another round of unsettled weather arrives late week.
Thursday looks partly sunny and calm, giving residents a window for outdoor chores, leaf cleanup, or Halloween prep. Friday’s Trick-or-Treat outlook remains mixed: early evening hours could stay dry, but new rain bands may move in later, especially along the coast and foothills. Parents should plan on umbrellas and waterproof layers for kids heading out after sunset.
By Saturday, another frontal system will likely spread rain across western Washington, marking the first of several early November waves. Temperatures stay mild for now, but cooler air builds next week — a sign the region’s early-winter rhythm is ready to begin. After all, the gray season always comes calling right on schedule.
