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.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: Mon, Apr 6, 2020: An upper level ridge currently sits over the central US and will remain stalled for the next couple days. This will bring south winds, warmer air, and moisture to the state over the next couple days. Low level clouds will limit mixing in the atmosphere and produce Yellow (moderate) AQI values across the Twin Cities. In addition, elevated smoke from the Flint Hills fires in eastern Kansas brought north by the winds is mixing down to the ground and will produce Yellow AQI values across western MN as well. A surface boundary passes through the state tomorrow morning. Early morning thunderstorms are possible in northern MN. Winds will switch from the northwest around mid day and bring in cleaner airmass into the state. Clouds will clear in the afternoon and mixing will improve as well. Temperatures will reach the 60s in the southern half of the state. On Wednesday a cold front passes through the state. Northwest winds will increase in speed and bring colder air into the state. Winds will remain northwest and temperatures will be colder again on Thursday. Green (good) AQI values are expected statewide tomorrow through Thursday.
