Forecast Discussion: Today, moderate and occasionally gusty southerly winds ahead of an approaching low-pressure system will transport some regional pollutants into Rochester, and mostly sunny skies and warm temperatures will support ozone formation. Therefore, AQI levels will be Moderate. Tomorrow, the low-pressure system will move through southeastern Minnesota, enhancing atmospheric mixing, producing widespread showers and thunderstorms, and shifting winds to northwesterly. These weather conditions will disperse pollutants in the Rochester area, leading to Good AQI levels. Tuesday, mostly sunny skies will aid ozone formation in southeastern Minnesota; however, moderate northwesterly winds will help to disperse pollutants. These conditions, combined with low regional pollutant carryover, will yield Good AQI levels. Wednesday through Friday, winds will shift to southerly as a low-pressure system develops over the central Plains, transporting regional pollutants into southeastern Minnesota. In addition, mostly sunny skies and warm temperatures will increase ozone formation, resulting in Moderate AQI levels on all three days.
