SEATTLE, Wash. – After a soggy Columbus Day, Western Washington residents can expect a major shift toward clear, crisp Fall weather starting Tuesday. Rainfall that has soaked I-5 commuters through the long weekend is tapering off early Monday night, giving way to blue skies, cooler mornings, and picture-perfect afternoons ideal for leaf viewing or outdoor school drop-offs.
According to the National Weather Service in Seattle, showers will diminish by Monday evening as a drier air mass builds over Puget Sound. Tuesday and Wednesday bring full sunshine and daytime highs near 59 degrees, with cool mornings in the low 40s. The transition marks the start of a calmer Fall pattern, perfect for post-holiday travelers and families heading back to work and school.
Winds will turn light from the north as skies clear, helping dry out wet roadways along I-5 and I-90 by early Tuesday. Drivers should still watch for slick spots in shaded areas and falling leaves that can make roadways slippery during the morning commute.
By midweek, forecasters say mild sunshine and calm winds will hold, with no significant rain chances until late Thursday. For those planning pumpkin patch trips or outdoor school events, conditions look favorable with crisp mornings and sunny afternoons — classic October weather across King and Snohomish Counties.
