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: Friday, July 19, 2019: A low pressure system is moving across central MN today. It will be mostly sunny and hot for most of the day, then scattered showers and thunderstorms will develop later in the afternoon across the central parts of the state. While severe weather is a threat for parts of the state, the very humid air mass and partial cloud cover tend not to favor much in the way of ozone, and thus ozone will likely remain Green (Good) for tomorrow. Particulate AQI should hold steady at Green as well. The cold front will push south overnight and tomorrow will see much cooler and drier weather. Clouds and scattered convection will keep AQI Green in most of the state. Canadian high pressure will build over the area on Sunday and Monday. Cooler temperatures and more pleasant weather will continue through Monday. Air quality is usually Green (Good) in these weather scenarios, however since airmasses will be arriving from Canada we'll keep an eye out for any possible smoke originating from wildfires in Canada and Alaska.
