Forecast Discussion: Today, southerly afternoon winds will transport pollutants into Rochester. However, low pollutant carryover from previous days will keep AQI levels Good. Tomorrow, as a weak low pressure system moves through Minnesota, southerly winds will gradually shift to west-southwesterly, dispersing pollutants and leading to Good AQI levels. Monday, moderate southerly winds ahead of an approaching cold front will transport regional pollutants and moisture into Rochester, increasing particle production. However, low pollutant carryover from the weekend will keep AQI levels Good. Tuesday through Thursday, moderate northwesterly winds behind a departing cold front will transport clean, cool air into Rochester, yielding Good AQI levels on all three days.
