Forecast Discussion: Today, moderate south-southwesterly winds will transport moisture and pollutants into Rochester, enhancing particle formation. Therefore, AQI levels will be Moderate. Tomorrow, a cold front will move through southeastern Minnesota, enhancing atmospheric mixing and shifting winds to west-northwesterly. These conditions will help to disperse pollutants. However, regional pollutant carryover from previous days will keep AQI levels Moderate. Monday and Tuesday, moderate to strong west-northwesterly winds will effectively disperse pollutants in the Rochester area. As a result, AQI levels will be Good on both days. Wednesday, lighter winds will reduce pollutant dispersion in Rochester; however, low-pollutant carryover from previous days will keep AQI levels Good. Thanksgiving, a fast-moving low-pressure system will move through southern Minnesota, shifting winds to northerly and enhancing mixing in the atmosphere. These winds will bring a cold, clean air mass into Rochester, yielding Good AQI levels.
