More heat in Washington forecast

The National Weather Service says 90-degree temperatures will return to Western Washington on Thursday and Friday.

Forecasters say a high pressure system and offshore flow will start pushing up temperatures on Wednesday. A push of marine air should cool things back down to the 70s and 80s for the weekend but bring the chance of thunderstorms.

In Eastern Washington, forecasters say high temperatures will be in the 90s all week with an increasing chance of thunderstorms by the weekend.
