Forecast Discussion: Today, moderate and occasionally gusty northwesterly winds behind a departing low-pressure system will effectively disperse pollutants in southeastern Minnesota, leading to Good AQI levels. Tomorrow, light northerly winds will persist in the Rochester region, continuing to disperse pollutants. As a result, AQI levels will remain Good. Saturday, southwesterly winds ahead of an approaching cold front will transport regional pollutants and moisture into Rochester, enhancing particle formation. However, low pollutant carryover from previous days will keep AQI levels Good. Sunday, the cold front will move through southeastern Minnesota, enhancing mixing and generating strong winds that will shift to northwesterly in the afternoon. These weather conditions will effectively disperse pollutants, yielding Good AQI levels. Monday and Tuesday, a weak surface low-pressure system will impact the Rochester area, enhancing mixing and producing moderate winds. These weather conditions will disperse pollutants, keeping AQI levels Good on both days.
