Forecast Discussion: Today, light to moderate westerly winds will disperse pollutants in Rochester. Therefore, despite warm temperatures and sunny skies increasing ozone formation, AQI levels will be Good. Tomorrow, a front will move through Rochester, enhancing vertical mixing in the atmosphere and generating moderate winds at the surface. These conditions will effectively disperse pollutants, leading to Good AQI levels. Monday and Tuesday, light to moderate northerly winds behind the departing front will transport a clean air mass into the region. As a result, AQI levels will remain Good on both days. Wednesday and Thursday, easterly winds developing ahead of an approaching low-pressure system will disperse pollutants in Rochester, keeping AQI levels Good on both days.
