Note: Some users might notice intermittent discrepancies in colors shown on the map of air quality monitors above, and those reported on the Department of Ecology's official page. This is because Ecology believes their method of calculating the air quality category (i.e. “Good”, “Moderate”, Unhealthy” etc) is more protective of public health in Washington. If in doubt as to which better represents public health risk, use the more stringent of the two (i.e. the map showing worse air quality).

Eastern Washington: fire weather and blowing dust concerns on Saturday (see below for Western WA)
While all this is unfolding, stronger winds will limit plume rise in existing fires, resulting in some smoke north of I-90 on Saturday. Chelan, Wenatchee and the Spokane area could see Moderate air quality from nearby fires but most other areas should remain Good unless new fires foul up the air.
Saturday's front ushers in a pattern shift toward cooler weather over the next few days, with little risk of strong winds and thunderstorms. This bodes well for firefighting efforts and should keep smoke reasonably well dispersed.
