Forecast Discussion: Today, northeasterly winds will bring a clean air mass into Rochester. In addition, mostly cloudy skies will reduce ozone formation. Therefore, AQI levels will be Good. Tomorrow, lighter winds will limit pollutant dispersion. However, partly cloudy skies will continue to reduce ozone formation. As a result, AQI levels will remain Good. Sunday through Wednesday, 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 four days.
