Forecast Discussion: Today, mostly cloudy skies and scattered showers will limit ozone formation, and moderate northeasterly winds will transport a clean air mass into the Rochester area. As a result, AQI levels will be Good. Tomorrow, northeasterly winds will continue to bring a clean air mass into the area. In addition, mostly cloudy skies will reduce ozone formation. Therefore, AQI levels will remain Good. Saturday, lighter winds will limit pollutant dispersion. In addition, partly to mostly sunny skies will enhance ozone formation. However, pollutant carryover from the previous days will be low. As a result, AQI levels will be Good. Sunday through Tuesday, moderate south-southeasterly winds will enhance mixing in the atmosphere, helping disperse pollutants. In addition, partly cloudy skies will limit ozone formation. These conditions will keep AQI levels Good on all three days.
