Forecast Discussion: Today, as high pressure builds into Minnesota, moderate northerly winds will disperse pollutants in Rochester, and partly to mostly cloudy skies will limit ozone production. As a result, AQI levels will be Good. Tomorrow, moderate becoming strong southerly winds ahead of an approaching cold front will effectively disperse pollutants in Rochester. Furthermore, increasing cloudiness will suppress ozone formation, leading to Good AQI levels. Labor Day, a cold front moving through Minnesota will produce scattered thunderstorms and moderate westerly winds, dispersing pollutants and leading to Good AQI levels. Tuesday and Wednesday, moderate west-southwesterly winds ahead of an approaching cold front will disperse pollutants in southeastern Minnesota. Therefore, despite mostly sunny skies enhancing ozone formation, AQI levels will be Good on both days. Thursday, moderate to strong southerly winds ahead of another approaching low-pressure system will continue to disperse pollutants in Rochester, keeping AQI levels Good.
