Forecast Discussion: Independence Day, light to moderate south-southwesterly winds will bring regional pollutants into southeastern Minnesota. Furthermore, mostly sunny skies and warmer temperatures will support ozone formation in the Rochester area. These conditions will result in Moderate AQI levels. Tomorrow, moderate southerly winds ahead of an approaching frontal boundary will transport additional pollutants into Rochester, and mostly sunny skies will continue to support ozone formation. Therefore, AQI levels will remain Moderate. Monday and Tuesday, as the weak front moves through southeastern Minnesota and departs to the east, moderate southwesterly winds will shift to north-northwesterly. These winds will disperse pollutants and bring a cleaner air mass into the Rochester area, leading to Good AQI levels on both days. Wednesday and Thursday, winds will shift to southerly as a low-pressure system develops over the central Plains, transporting regional pollutants into southeastern Minnesota. In addition, partly to mostly sunny skies and warm temperatures will aid ozone formation, resulting in Moderate AQI levels on both days.
