Forecast Discussion: Today, a low-pressure system will move through Iowa, shifting winds to northerly in southeastern Minnesota. These winds will bring a cold, clean air mass into the region, yielding Good AQI levels. Thanksgiving Day, moderate northwesterly winds will persist behind the departing low-pressure system, continuing to transport cold, clean air into the Rochester area. As a result, AQI levels will remain Good. Friday, as another low-pressure system approaches from the west, light southerly winds will develop in southeastern Minnesota, transporting regional pollutants into the area. Therefore, AQI levels will be low-Moderate. Saturday, the low-pressure system will move through Minnesota, enhancing mixing in the atmosphere and shifting winds to north-northwesterly. These weather conditions will effectively disperse pollutants in Rochester, lowering AQI levels to Good. Sunday, moderate north-northwesterly winds will persist behind the departing low-pressure system, continuing to disperse pollutants and yielding Good AQI levels. Monday, lighter winds will reduce pollutant dispersion in the Rochester area. However, low pollutant carryover from previous days will keep AQI levels Good.
