Smoke visible in the Missoula area Monday dropped the air quality to "moderate." The smoke is likely coming from the Klamathon Fire in California.
Sarah Coefield of Missoula City-County Health Department said the fire is burning about 35,000 acres near the California/Oregon border.
Smoke that can be seen in the sky in other parts of Montana is coming from fires in Nevada and Wyoming.
Based on winds, Coefield said smoke should blow out of the Missoula area by tomorrow. Air quality is expected to return to "good" by this evening.
