Forecast Discussion: Today, despite mostly sunny skies and very warm temperatures enhancing ozone formation in Rochester, moderate southeasterly winds will keep the lower levels of the atmosphere well-mixed. As a result, AQI levels will be Good. Tomorrow, moderate southerly winds will gradually transport pollutants into the region. However, low regional pollutant carryover will keep AQI levels Good. Sunday, as a low-pressure system approaches Minnesota, increasing clouds will reduce ozone formation and scattered thunderstorms will enhance mixing. Furthermore, moderate south to southwesterly winds will disperse pollutants. As a result, AQI levels will be Good. Labor Day through Wednesday, mostly cloudy skies will limit ozone formation, and moderate winds will effectively disperse pollutants in Rochester. These conditions will keep AQI levels Good on all three days.
