Forecast Discussion: Today, light to moderate southerly winds will develop ahead of an approaching cold front, transporting pollutants and moisture into Rochester. These conditions will enhance particle formation, leading to low-Moderate AQI levels. Tomorrow, the cold front will move through Rochester midday, shifting winds from southerly to northwesterly. These weather conditions will effectively disperse pollutants, yielding Good AQI levels. Wednesday, moderate northwesterly winds will bring clean, cold air into the Rochester area, keeping AQI levels Good. Thursday, surface high pressure building south of the Great Lakes will cause moderate southwesterly winds to develop, transporting some pollutants into southeastern Minnesota. However, low regional pollutant carryover from previous days will keep AQI levels Good. Friday and Saturday, light to moderate west-northwesterly winds will disperse pollutants and bring clean air into Rochester, yielding Good AQI levels on both days.
