Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)

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.

Forecast Discussion: Today and tomorrow, light southerly to southeasterly winds will bring pollutants and moisture into Rochester, enhancing particle formation. However, a series of upper-level low pressure systems passing over southern Minnesota will enhance vertical mixing. Therefore, AQI levels will be Good on both days. Sunday and Monday, a low pressure system will move through Rochester, shifting winds to northerly and gradually bringing clean air into southern Minnesota. Therefore, AQI levels will be Good on both days. Tuesday and Wednesday, another low pressure system passing to the south of Rochester will generate moderate winds, aiding pollutant dispersion. In addition, pollutant carryover from previous days will be low. Therefore, AQI levels will remain Good on both days.
