Forecast Discussion: Today, light to moderate northeasterly winds will disperse pollutants in the Rochester area, leading to Good AQI levels. Tomorrow, light northerly winds will gradually bring a clean air mass into Rochester, keeping AQI levels Good. Tuesday and Wednesday, light northerly winds will continue to transport clean, dry air into Rochester, limiting particle formation and yielding Good AQI levels on both days. Thursday and Friday, southerly winds ahead of an approaching weak cold front will bring regional pollutants into Rochester. As a result, AQI levels will be low-Moderate on both days.
