Looking Ahead:

Friday will be the warmest day of the week with plenty of sunshine and the low 80s. The upper level low offshore will swing in Friday night into Saturday, increasing clouds, cooler temperatures and bringing the chance of showers. There could also be enough instability on Saturday that we could see a lightning strike, especially for the north interior. We start to dry out again Sunday with slowly warming temperatures and more sunshine into early next week. 

Seattle Extended

Friday will be the warmest day of the week with plenty of sunshine and low 80s.
