Is summer weather coming to an end? I’ll get to that answer later, yet a change in the recent warm weather is expected to unfold this weekend and into the first half of next week.

An upper-level low well off the coast is forecast to spin clouds, spotty light showers, and cooler temperatures onshore during the weekend. Any rain amounts are anticipated to be limited.

A threat of late-day thunderstorms is possible in the mountains Saturday, mainly in the Cascades. So if there are plans to be in the mountains this weekend, be prepared for the possibility of lightning.

High temperatures in western Washington this weekend are expected to cool into the lower to mid-70s, with 60s along the outer coast. The average early September high temperature in the Puget Sound region is in the mid-70s.
