Limited clearing this afternoon

Air quality today is forecast to range mostly from Good to Unhealthy for Sensitive Groups. The Treasure Valley may experience brief periods of Unhealthy. 

Expect limited clearing of smoke everywhere in the afternoon with increased mixing heights and wind speeds. Come night, however, any lingering smoke and haze will become trapped under surface temperature inversions and settle in valleys and low-lying areas, worsening air quality until those inversions break tomorrow morning. 

An Air Quality Advisory is still in place for Ada, Canyon, Gem, Payette, and Washington Counties. 

NOAA GOES-West GeoColor (true color) visible satellite image captured at 9:36 a.m. MDT on July 21, 2026 shows clouds passing over and areas of smoke visible over Washington, Central Oregon, and portions of Idaho.
