Forecast Discussion: Today, moderate east-southeasterly winds will effectively disperse pollutants in the Rochester area, yielding Good AQI levels. Tomorrow, as a cold front approaches from the west, moderate south-southeasterly winds ahead of it will bring pollutants into the Rochester area. However, low pollutant carryover from Tuesday will keep AQI levels Good. Thursday through Saturday, as the cold front moves through Minnesota and surface high pressure builds over the Plains, gusty northwesterly winds will disperse pollutants and bring clean, cool air into the Rochester area. These conditions will limit particle formation, leading to Good AQI levels on all three days. Sunday, another cold front will move through Minnesota, producing moderate northwesterly winds that will disperse pollutants in the Rochester area. As a result, AQI levels will remain Good.
