Seattle, Washington – Sunshine will dominate across western Washington on Wednesday, July 30th, as Seattle climbs to a high near 83°F — marking one of the warmest days this week before a cooler, wetter pattern develops by Friday night.
According to the National Weather Service, calm winds will shift to the northwest by mid-afternoon, keeping conditions dry and mild across King County. No precipitation is expected during the day, but residents should prepare for a 20% chance of showers returning Thursday after 11 a.m., particularly impacting outdoor plans and commutes along I-5 and I-90.
While Wednesday remains picture-perfect, the shift begins late Thursday and builds into the weekend. Friday night through Saturday morning could bring scattered showers, making it wise to reschedule lawn work or early hikes. Drivers should stay alert on Friday night as roads may become slick with scattered light rain — especially in low-lying and shaded areas.
Looking ahead, temperatures dip to the mid-70s by Friday and Saturday, offering some relief from this week’s heat. By Monday, August 4th, another round of showers may develop across the Puget Sound, with daytime highs hovering around 73°F.
⚠️ What’s Next: Expect breezy conditions Thursday afternoon and prepare for a possible damp weekend. Pack a rain layer and check back for evolving alerts.
