Forecast Discussion: Today, light to moderate southwesterly winds will gradually transport pollutants into the Rochester area. However, low pollutant carryover from previous days will lead to Good AQI levels. Tomorrow, moderate southwesterly winds will bring additional pollutants and moisture into the Rochester area, enhancing particle formation and resulting in low-Moderate AQI levels. Saturday and Sunday, moderate west- to northwesterly winds will bring a clean air mass into southeastern Minnesota, yielding Good AQI levels on both days. Monday and Tuesday, southerly winds will develop in the Rochester area as a low-pressure system passes to the north. These winds will transport regional pollutants and moisture into southeastern Minnesota, enhancing particle formation and leading to low-Moderate AQI levels on both days.
