Forecast Discussion: Today, calm overnight winds have allowed pollutants to accumulate at ground level in the Rochester area. However, moderate east-southeasterly winds developing ahead of an approaching cold front will help to disperse pollutants, resulting in Good AQI levels. Tomorrow, the cold front will move through southeastern Minnesota, enhancing vertical mixing in the atmosphere and generating northwesterly winds. These weather conditions will effectively disperse pollutants, keeping AQI levels Good. Monday through Thursday, moderate to strong northwesterly winds will persist behind the departing cold front, transporting a clean air mass into the Rochester region. Therefore, AQI levels will remain Good on all four days.
