Seattle weather: A toasty Seafair weekend

Seattle weather: Mostly sunny Seafair weekend

FOX 13 Seattle Meteorologist Ilona McCauley has your latest western Washington weather forecast!

There was a noticeable haze in the air today. Luckily, it did not impact our air quality in Puget Sound, but it remains poor to our east. Smoke should push east as onshore flow picks up Saturday. Some haze might be left over, but it won't be as smoky for the weekend.

Upper-level smoke will clear out little from Western Washington on Saturday.

It is a BIG weekend around Seattle with Seafair and several sporting events going on. While we are expecting a few more clouds for Saturday, it will still remain warm with highs well into the 80s. Be prepared with plenty of water and take breaks in the shade when possible.
