Forecast Discussion: Today, moderate and gusty northwesterly winds behind a departing cold front will effectively disperse pollutants and transport clean air into Rochester. As a result, AQI levels will be Good. Tomorrow, light to moderate northwesterly winds will continue to disperse pollutants in Rochester, keeping AQI levels Good. Thursday, surface high pressure over the region will generate light westerly winds, limiting pollutant dispersion. However, pollutant carryover from previous days will be low. Therefore, AQI levels will remain Good. Friday and Saturday, as another high-pressure system approaches from the north, light to moderate northwesterly winds will develop, aiding pollutant dispersion in Rochester and keeping AQI levels Good on both days. Sunday, moderate southerly winds will bring regional pollutants into Rochester. However, these winds will also help to disperse pollutants and keep the lower levels of the atmosphere well mixed. Therefore, AQI levels will remain Good.
