Air Quality and Dispersion Discussion for September 18, 2018

Welcome to the fall burning season. Check here for an overview of air quality and dispersion conditions around western Montana. Please check this website everyday for air quality related burn restrictions.

The trough of low pressure that has been impacting Montana for the past week will continue to be the main driver for Montana weather this week. For Tuesday, this means generally dry conditions in western Montana, but a chilly start to the day with moderately strong inversions causing poor dispersion in the valley until about 9am. Surface winds on Tuesday will generally be from the northwest at 5-10 mph by the afternoon. A system is expected to move through on Wednesday, bringing a chance of rain to many parts of western Montana, especially along the Divide. Surface winds will be turning easterly overnight Tuesday, and remain from the east throughout the day on Wednesday. Dispersion is expected to be good at higher elevations on Wednesday, with low clouds in the valleys expected to create only moderate dispersion conditions there. Dispersion conditions are expected to improve on Thursday. Air quality throughout this period is expected to be good to moderate overnight, improving to good each afternoon. Small, narrow valleys may see more persistent moderate air quality overnight Monday into Tuesday due to wood stove use.

There are no air quality related outdoor burning restrictions for Tuesday, September 18th. However, local fire restrictions are still in place for many Montana counties. You must have approval from your local fire authority to burn.

Be sure to check out current air quality, which can be found on the Today’s Air site
