Forecast Discussion: Labor Day, a cold front moving through Minnesota will produce scattered thunderstorms and moderate westerly winds, dispersing pollutants and leading to Good AQI levels. Tomorrow, light to moderate westerly winds behind the departing cold front will continue to disperse pollutants in Rochester. Therefore, despite mostly sunny skies enhancing ozone formation, AQI levels will remain Good. Wednesday and Thursday, moderate to strong southerly winds ahead of an approaching low-pressure system will effectively disperse pollutants in southeastern Minnesota, keeping AQI levels Good on both days. Friday, a cold front will move through Rochester, generating moderate northwesterly winds that will disperse pollutants and transport a cleaner air mass into the Rochester region. In addition, partly cloudy skies will suppress ozone formation. These conditions will yield Good AQI levels. Saturday, light to moderate northerly winds behind the departing cold front will continue to bring cleaner air into Rochester, keeping AQI levels Good.
