Forecast Discussion: Today, light to moderate northerly winds will transport a clean air mass into Rochester, yielding Good AQI levels. Tomorrow, mostly sunny conditions will enhance ozone formation, and light southeasterly winds will inhibit pollutant dispersion. However, low pollutant carryover from Tuesday will result in Good AQI levels. Thursday and Friday, moderate southeasterly winds developing ahead of an approaching low-pressure system will disperse pollutants in Rochester. Furthermore, mostly cloudy skies and scattered thunderstorms will limit ozone production. Therefore, AQI levels will be Good on both days. Saturday and Sunday, light to moderate southeasterly winds will gradually transport regional pollutants into Rochester. However, low pollutant carryover from Thursday and Friday will keep AQI levels Good on both days.
