Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.

Forecast Discussion: Canadian wildfire smoke is still expected to reach Moorhead this afternoon and evening, so the yellow (moderate) AQI forecast continues there. Otherwise green AQI levels are expected for the rest of the state Thursday. Areas of smoke will continue the potential for yellow AQI conditions on Friday in western Minnesota, possibly reaching into northern Minnesota in the afternoon and evening. Widespread yellow AQIs are then expected over the weekend as a larger plume of Canadian wildfire smoke approaches the area. While it's still early, we're watching the potential for air quality alert conditions to develop on Sunday as smoke concentrates along a cold front. As the details become more clear over the next couple of days, we encourage you to check back for forecast updates.
