Forecast Discussion: Today, breezy southerly winds ahead of an approaching low-pressure system will increase mixing and pollutant dispersion in Rochester, yielding Good AQI levels. Tomorrow, a low-pressure system moving through Minnesota will produce scattered thunderstorms and moderate west-northwesterly winds, effectively dispersing pollutants and bringing clean air into Rochester. Therefore, AQI levels will remain Good. Sunday and Monday, moderate west-northwesterly winds behind the departing low-pressure system will keep pollutants well dispersed in Rochester, resulting in Good AQI levels on both days. Tuesday and Wednesday, light to moderate southerly winds will reduce pollutant dispersion, and mostly sunny skies and warm afternoon temperatures will aid ozone formation in Rochester. However, low day-to-day regional pollutant carryover will result in Good AQI levels on both days.
