SEATTLE — After more high temperatures in the Puget Sound region, the National Weather Service says the warm spell will end this evening as marine air surges across Washington.
A heat advisory expires at 6 p.m. today after highs expected around 90. Forecasters say the Friday and Saturday highs will be about 20 degrees cooler.
The temperature hit record highs Wednesday of 89 at Sea-Tac Airport and 89 at Olympia.
The Weather Service says the changing pattern will bring a chance of thunderstorms Friday in Eastern Washington, some possibly with hail, gusty winds and heavy rains.
