Smoke Forecast for Tuesday, August 12 2025 9:30 AM

  • August 12 2025

Current Conditions

Wildfire activity is beginning to pick up across the region thanks to moderating temperatures and gusty afternoon winds.

Warmer temperatures and breezy afternoon winds will lead to additional fire growth and increased smoke production on many regional wildfires Tuesday. The Lightning Creek fire just east of Sandpoint, Idaho, has grown to 2,461 acres. It is 0% contained. It will send some smoke into Lincoln and Flathead Counties in the coming days. The Big Bear and Rush fires continue to burn in the Bitterroot Range of central Idaho, just southwest of the Bitterroot Valley. The Big Bear fire has grown to 14,935 acres and is 70% contained, while the Rush fire is up to 7,392 acres and is 90% contained. The Big Bear fire exhibited more active fire behavior on Monday compared to previous days. Thanks to warm air, low humidity, and gusty winds, expect this trend to continue.

At 9:00 AM Tuesday, Libby's air quality is Moderate.

By Wednesday evening, the HRRR smoke model shows smoke from regional wildfires impacting the western third of Montana.

Forecast

Warm temperatures, gusty afternoon winds, and low humidity will lead to more active fire weather behavior across the region between Tuesday and Wednesday. Fuel moistures over much of southwest Montana remain seasonably dry and new fire starts are certainly a concern in this environment. Southwesterly transport winds will begin to bring light surface smoke from wildfires burning in central Idaho into portions of Ravalli and Beaverhead Counties. A shower or two is possible but most of this precipitation will remain along the Continental Divide and the Canadian border.

By Wednesday night and Thursday, a dry cold front will move across the Treasure State, bringing an end to the unseasonable warmth. However, afternoon winds will remain gusty, and this could provide more active fire behavior across the region.

Recent precipitation across northern Saskatchewan and Manitoba has moderated fire behavior and decreased smoke production. As a result, smoke from Canadian wildfires over the northern United States won't be nearly as impactful as it has been for much of the summer.

However, prrecipitation across Montana will be limited over the next seven days. This will likely be the longest dry stretch much of the state has endured this summer. The pattern will help to further dry out fuels and lead to more active fire behavior and increased smoke production on existing regional wildfires. Stay tuned!

Conditions can change quickly as weather could stimulate active fires and the likelihood of new starts increases. Please keep track of concentrations at todaysair.mtdeq.us or the Fire and Smoke Map.
