Some clearing today

Today’s air quality is forecast to be Good to Unhealthy for Sensitive Groups.

Currently, patchy smoke and haze are seen across South Idaho, East Idaho, and the Central Mountains. Light smoke and haze are visible in North Idaho.  The westerly afternoon winds and potential thunderstorms will continue to help disperse near surface smoke and haze. The wind will further nudge the smoke and haze eastward and into Montana, Wyoming, and Utah. Light smoke and haze will linger across South Idaho, East Idaho, and the Central Mountains with areas of smoke near local fires tomorrow afternoon. As temperatures decrease overnight, lingering smoke can become trapped under surface temperature inversions and raise local AQI levels until inversions break in the late morning, offering limited clearing.  The highest AQI levels will be seen around the regional and local fires.

HRRR-NCEP Near Surface Smoke initialized at 6am MDT July 30, 2024 shows patchy smoke and haze over South Idaho, East Idaho, and the Central Mountains. Localized smoke is seen blowing east from regional fires.
