Forecast Discussion: Today, as surface high pressure moves over the region, light winds will limit pollutant dispersion in Rochester. However, pollutant carryover from previous days will be low. Therefore, AQI levels will be Good. Tomorrow, as a high-pressure system approaches from the north, moderate northwesterly winds will develop, aiding pollutant dispersion and keeping AQI levels Good. Saturday, winds will diminish and shift to southerly in Rochester, reducing mixing and dispersion. However, a clean, dry air mass over the region will limit particle production, yielding Good AQI levels. Sunday, moderate southerly winds ahead of an approaching low-pressure system will help to disperse pollutants and keep the lower levels of the atmosphere well mixed. Therefore, AQI levels will remain Good. Monday, westerly winds behind the departing low-pressure system will disperse pollutants in Rochester, keeping AQI levels Good. Tuesday, lighter winds will reduce pollutant dispersion. However, low pollutant carryover from Monday will lead to Good AQI levels.
