Forecast Discussion: Today and tomorrow, the weak low-pressure system will move through Minnesota and depart to the east, enhancing vertical mixing in the atmosphere and shifting winds to northerly. These weather conditions will effectively disperse pollutants and transport cleaner, drier air into southeastern Minnesota, leading to Good AQI levels on both days. Saturday and Sunday, moderate southeasterly winds will develop as another low-pressure system develops over the Dakotas, bringing some pollutants and moisture into Rochester. However, low regional pollutant carryover from day to day will result in Good AQI levels on both days. Monday, the low-pressure system will move through Minnesota, shifting winds to northerly and effectively dispersing pollutants in Rochester. As a result, AQI levels will remain Good. Tuesday, as the low-pressure system departs Minnesota, moderate westerly winds behind it will disperse pollutants, leading to continued Good AQI levels.
