Communities like Seattle, Tacoma, Snoqualmie Pass, Everett and Bellingham will be even hotter than what we experienced yesterday. As a corridor of hot, dry air moves east over Puget Sound and the Cascades today, temperatures will cool substantially along the coast. Highs in the South Sound will be a few degrees cooler than yesterday.

This afternoon, there could be high-level clouds and high-level smoke coming from fires burning in Oregon and California. I'm not expecting air quality to drop at the surface. The smoke may enhance the sunset colors tonight. Any lingering haze will get pushed out of Western Washington tomorrow.

Stay hydrated today! If you don't have air-conditioning at home, I might recommend heading into a building with A/C (e.g. a mall or movie theater) if you want to give yourself a break from the heat. Mercifully, temperatures will drop considerably on Monday.

80 degree weather is expected in Seattle Sunday.

Fire danger is elevated today over the Central and South Cascade mountains. Remember to obey burn bans, keep cars off of dry grass and properly discard cigarettes. Any fires that start today have the potential of spreading more rapidly than under normal conditions.

Tomorrow, there might be some thunderstorms across the Cascades.

High fire danger and dry weather are in store for the Cascades east of Seattle Sunday.

Labor Day will be noticeably cooler and grayer for Western Washignton thanks to our famous "marine layer" (cool, cloudy air coming from the Pacific Ocean).
