Dispersion and Air Quality Forecast
Saturday (10/25): Dispersion is expected to be good on Saturday due to unstable southwesterly winds. Air quality is expected to be good at most locations. Cold overnight temperatures and moderate inversions may lead to elevated wood stove smoke impacts in some mountain valleys.
Sunday (10/26): Dispersion is expected to be good Sunday due to unsettled weather moving through the area. Air quality is expected to be good in all locations. The approaching low pressure trough on Sunday morning should mitigate wood stove smoke impacts in most mountain valleys.
Monday (10/27): Dispersion is expected to be good Monday due to unsettled weather moving through the area. Air quality is expected to be good in most locations. Cold overnight temperatures may lead to elevated wood stove smoke impacts, but unsettled weather should help clear any built up smoke quickly.
Saturday (10/25): The front moving through on Friday will exit the region to the north by Saturday morning. A ridge of high pressure will briefly build into the area, leading to dry and warm conditions for many locations. Overnight inversions should break by mid-morning as southwest flow destabilizes the atmosphere. Surface winds will be from the south southwest and transport winds will be shifting from the west to the southwest throughout the day.
Sunday (10/26): A low pressure trough will move across western Montana on Sunday, bringing scattered precipitation and cooler temperatures. Surface winds will be from the west and transport winds will be from the southwest, shifting to the west as the trough passes. Overnight inversions will likely be weak due to increased winds as the system approaches.
Monday (10/27): The low pressure trough axis will be moving across eastern Montana by Monday morning. Scattered precipitation is expected in both western and eastern Montana. Surface winds will be from the west in areas behind the trough and from the northwest as the trough passes over. The precipitation will end from west to east by Tuesday morning.

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.
