Dispersion and Air Quality Forecast
Dispersion is expected to be good on Wednesday, October 22, 2014. Air quality is expected to be good in most locations. Some locations may see wood stove smoke impacts build up due to cold overnight temperatures. Air quality in Libby reached unhealthy for sensitive groups on Tuesday due to wood stove impacts. Cold overnight temperatures may lead to elevated concentrations on Wednesday as well.
Unsettled weather will dominate the next few days. The trof of low pressure that brought clouds, rain, and breezy continues to western Montana on Tuesday will exit the area on Wednesday. Winds will stay on the breezy side throughout the day prior to the arrival of another trof on Thursday. Surface winds will be from the south southwest in areas west of the Divide and from the west in areas east of the Divide. Overall, there will be good mixing conditions, however, the cold overnight temperatures may lead to decreased air quality in some valleys due to the build-up of wood stove smoke.
Open Burning Restrictions
Open burning is restricted below 2500 ft. in Lincoln county due to elevated wood stove smoke on the valley floor. Open burning in Cascade, Flathead, Missoula, and Yellowstone counties, and within the Libby Impact Zone, is at the discretion of the county air quality program. The contact information for these counties is provided below.

If you have submitted a written request and received permission with a burner identification number, please adhere to the instructions below. The Department will be working hard all winter to assess dispersion conditions and expected air quality in your area, and identify a timeframe that will minimize the impacts of your proposed burns to air quality.
- Please check this website often. It will be updated Monday through Friday, excluding holidays, by 5:00 pm. Burning “windows of opportunity” are infrequent and forecasts are subject to change.
- Determine if your assigned wintertime burn identification number is listed as having a possible “window of opportunity” on a given day. If so, call the Department's Open Burning Program Permitter Doug Kuenzli at 444-4267 at least 24 hours prior to the proposed date to create a burn plan. Please only call between 8:00 am-4:00 pm.
- Notify local fire control authorities prior to igniting your burn.
- At the completion of your burn, call the meteorologist to note the accomplishment achieved and indicate whether any future service will be required.
Thank you for working with the Air Resources Management Bureau to accomplish your burn.
