Seattle gets one more mild afternoon Wednesday before the umbrellas reclaim the week. Skies are clear early near Boeing Field, with temperatures around 41 degrees, but clouds will build and light rain may arrive after 4 p.m.
The high should reach about 57 degrees before temperatures ease back through the afternoon. The National Weather Service puts Wednesday’s rain chance at 80%, with new amounts likely staying below a tenth of an inch.
Rain Picks Up Wednesday Night
Wednesday night is when the forecast turns properly wet, with a 90% chance of rain. Southerly winds increase during Wednesday afternoon and evening, reaching 8 to 11 knots at KSEA, then slowly ease after the front moves through late Wednesday. The low should sit near 49 degrees, with temperatures rising slightly overnight as the front moves through.
Thursday brings a slight chance of morning rain followed by mostly cloudy skies. Another round of rain is likely after 4 a.m. Friday, followed by a cloudy day with a 70% chance of rain and a high near 55.
Wetter Pattern Builds Into The Weekend
Friday’s rain could total between 0.50 and 1.00 inches in the interior through Friday night, while Saturday may be the warmest day of the stretch at around 61 degrees. A chance of light rain remains, and the next wetter push arrives Saturday night before rain likely continues Sunday, with a high near 56.
Rain chances remain in the forecast Monday and Tuesday, keeping the broader pattern active well beyond the midweek change. That is a more substantial turn than the mostly dry setup described in Hoodline’s Tuesday forecast.
Coastal Winds Warrant Extra Attention
Seattle has no land-based weather watches or warnings in the supplied forecast, but marine conditions will deteriorate. Small craft advisories begin Wednesday across coastal waters and parts of the Strait of Juan de Fuca, while stronger winds and higher seas are expected with the next systems Thursday night and Friday.
