Seattle, Wash. – A quiet, partly cloudy start to the week will soon give way to the return of the Pacific Northwest’s trademark rain. After a stretch of dry skies and mild afternoons, a new system is on track to sweep into the Seattle area by midweek, bringing wet roads, gray skies, and that familiar October rhythm of umbrellas and headlights glowing through drizzle.
According to the National Weather Service in Seattle, Monday and Tuesday will stay mostly dry with highs near 60°F, but a stronger front arrives Wednesday afternoon. Rain chances climb sharply by late day, with widespread showers expected across the metro and along the I-5 corridor into Thursday morning. The heaviest rain will likely hit during the Wednesday evening commute, when gusty south winds could slow traffic and reduce visibility.
Residents should plan for slick streets and possible ponding on secondary roads. Outdoor workers and event planners will also need to prepare for wet conditions through at least Thursday afternoon. Temperatures remain seasonable, with highs in the lower 60s and lows in the upper 40s — mild enough to prevent frost but cool enough to signal the region’s steady slide toward winter.
Beyond Thursday’s front, models suggest another round of light rain could arrive late in the week before clearing just in time for the weekend. Friday and Saturday may bring brief sunshine breaks between passing clouds — a welcome window before the next Pacific wave likely rolls in by early next week.
