Forecast Discussion: Today, as a cold front approaches from the west, gusty south-southeasterly winds ahead of it will disperse pollutants in the Rochester area, resulting in Good AQI levels. Tomorrow, as the cold front moves through Minnesota, winds shifting to westerly will disperse pollutants and bring clean air into the Rochester area, yielding Good AQI levels. Friday, lighter winds will reduce pollutant dispersion in the Rochester area. However, low pollutant carryover from Thursday will lead to Good AQI levels. Saturday, surface high pressure over the central Plains will produce moderate northwesterly winds in the Rochester area, dispersing pollutants and keeping AQI levels Good. Sunday and Monday, as a low-pressure system approaches from the west, moderate south-southeasterly winds ahead of it will bring pollutants and moisture into the Rochester area, aiding particle formation. While low pollutant carryover will keep AQI levels Good on Sunday, AQI levels will increase to low-Moderate on Monday.
