Briefings
From the Forecaster
Wildfire Smoke and Hot
Created by the NWS Missoula WFO
Dry conditions are expected to persist across the Northern Rockies for the foreseeable future. With deep southwesterly flow transporting smoke from active fires in Washington and Oregon, air quality will likely remain poor, and it may get worse before it gets better. We remain locked into a synoptic setup featuring elevated fire weather conditions. Specifically hot, dry, and breezy weather. This pattern continues to stream smoke into the region, degrading air quality and reducing visibility. - Stay cool and limit outdoor exposure when smoke is thickest. - Check in on vulnerable neighbors, friends, and family, especially those without air conditioning or with respiratory ailments. - Always check the back seat for pets or children.
