Forecast Discussion: Today, northwesterly winds will diminish and shift to southeasterly late in the day as a low-pressure system approaches from the southwest, limiting pollutant dispersion in the Rochester area. However, low regional pollutant carryover from previous days will keep AQI levels Good. Tomorrow, moderate south-southeasterly winds ahead of the approaching low-pressure system will bring pollutants and moisture into southeastern Minnesota. These conditions will increase particle production, leading to low-Moderate AQI levels. Sunday through Tuesday, the low-pressure system will impact Minnesota, enhancing atmospheric mixing, producing widespread showers and thunderstorms, and generating moderate winds. These weather conditions will effectively disperse pollutants in the Rochester area, resulting in Good AQI levels on all three days. Wednesday, moderate westerly winds behind the departing low-pressure system will help to disperse pollutants and bring a clean air mass into southeastern Minnesota. As a result, AQI levels will remain Good.
