Forecast Discussion: Today and tomorrow, light to moderate north-northeasterly winds will transport a clean, cool air mass into Rochester, yielding Good AQI levels on both days. Saturday and Sunday, light to moderate north-northeasterly winds will continue to bring a clean air mass into the Rochester region. In addition, cool temperatures will limit ozone formation. Therefore, AQI levels will remain Good on both days. Monday and Tuesday, southeasterly winds will develop ahead of an approaching low-pressure system, dispersing pollutants and keeping AQI levels Good on both days.
