Today's Report and Forecast Today's Summary
Air quality is GOOD at all locations this morning. All large, active fires in Montana are showing minimal fire behavior. Many locations in Montana experienced showers over the last 24 hours and temperatures are hovering in the 40s and 50s across most of the state this morning. These conditions have led to clear skies and fall-like weather.

The wet, cold weather will continue through the weekend. Rain is expected to become widespread this evening through tomorrow night and finally tapering on Sunday. Rain totals over one inch are likely across the state and many areas in the mountains and eastern Montana may receive up to 2 inches

Throughout this period air quality is expected to remain GOOD at all locations. Any smoke from distant fires that enters Montana will wash out quickly and is not expected to impact air quality. Air quality impacts may return next week when drier, more seasonable weather is expected to return.
Air quality is GOOD at all locations. Rain and cool temperatures are expected across the entire state today and lasting through the weekend. Air quality is expected to remain GOOD throughout this period. This site will be updated again when smoke impacts return to the state.
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.
