AQI: Good (0 - 50) AQI: Good (0 - 50)
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.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.

Forecast Discussion: Thursday, September 19, 2019: A stationary boundary exists near the Minnesota/Iowa border with clouds leftover from the morning showers/thunderstorms inundating the southeastern corner of the state. Southeasterly winds over much of the state today and gradually shifting to southerly tonight. Green (good) air quality conditions statewide. A slow-moving low pressure system will move into the western/central Dakotas on Friday allowing for increasing southerly winds over Minnesota. With these winds will come increased temperatures and humidity along with scattered clouds with a few isolated showers and thunderstorms. With the return of southerly winds, fine particle pollution is expected to increase as they have been been traced back to the various fires in the lower Mississippi Valley into the southeastern US. Ozone values will also be on the increase over the southern 1/2 of the state . Yellow (moderate) AQI values are possible in areas of southern and central Minnesota including the Twin Cities metro area, St. Cloud, and Rochester on Friday. Green air quality conditions to be the norm for most of northern and north central Minnesota. Late Friday night into Saturday morning showers and thunderstorms will be on the increase in western parts of the state, and then the rest of Minnesota during the afternoon/evening hours. Air quality conditions to become all Green for most of the state with a few higher hourly spikes until the storms move through. Sunday, northwest winds behind the frontal system are expected to clear out any pollutants restoring Green AQI conditions statewide.
