Warmer weather coming

GOOD to MODERATE air quality for the majority of the state today. The highest AQI levels will be seen around those fires localized to the Central Mountains and North Idaho. Those areas could experience brief periods of UNHEALTHY FOR SENSITIVE GROUPS.

Over North Idaho, light smoke and haze will linger through the day with limited clearing this afternoon before more light to patchy smoke and haze moves in from Washington and British Columbia and remains overnight. Central Idaho will see light smoke and haze drift south from North Idaho this afternoon and linger overnight. Light smoke and haze over East Idaho will clear this afternoon. Light smoke and haze will drift southward out of the Central Mountains this evening across South Idaho and linger overnight. As temperatures decrease tonight, lingering smoke and haze across Idaho will become trapped under surface temperature inversions and settle in valleys and low-lying areas which will raise local AQI levels until the inversions break later in the morning. With warmer and drier conditions forecasted for the future, look for smoke production to possibly increase towards the end of the week.

NOAA GOES-West GeoColor (true color) visible satellite image captured at 15:21 UTC (9:21 a.m. MDT) on 15 September 2025 shows extensive cloud cover over Central and North Idaho. Smoke is visible in Central California.
