Updated Thursday, September 1 at 1:20pm: The Billings air quality has dropped from good to moderate Thursday afternoon because of wildfire smoke.

Montana’s DEQ is listing Billings air in the yellow color which means people who are unusually sensitive should consider limiting prolonged outdoor exertion.

And even people without known breathing issues may notice their throat feels a little scratchy. Drink extra water.

We expect hazier skies today due to smoke from the wildfires to our west. A cold front will bring shifting winds and should improve our smoke situation for tomorrow. 

The DEQ is listing Billings with Good air quality as of early Thursday morning; that’s expected to change as the day goes on.

Poorer air quality from wildfire smoke is caused by higher particulate matter which can cause headaches and more difficulty breathing for those who have pre-existing health issues including asthma and COPD.

Stay indoors if possible and use indoor HEPA filters.
