Today's Report and Forecast Today's Summary
Due to relatively low fire activity and smoke production across California, Idaho, and Montana on Saturday and Sunday, we did not experience much if any smoke this morning across southwestern Montana. Skies are very clear and air quality is GOOD around the state. Air quality and visibility should also remain GOOD across the state through the rest of the day, despite very warm southwestern winds high in the atmosphere. There will be a chance of thunderstorms and a small cold front tonight. Air quality due to wildfire smoke will remain GOOD throughout the week with a cooler, active weather pattern.
Residents near active fires and under plumes aloft need to remain aware of current conditions and use the visibility guidelines to guide their activity decisions as the situation changes.
