Forecast Discussion: Today, a cold front moving through southeastern Minnesota will enhance atmospheric mixing and generate strong westerly winds in the Rochester area. These weather conditions will effectively disperse pollutants, yielding Good AQI levels. Tomorrow, light to moderate southwesterly winds will develop as a weak surface low-pressure system moves into northern Minnesota, dispersing pollutants and keeping AQI levels Good. Tuesday, moderate west-northwesterly winds will disperse pollutants in southeastern Minnesota, leading to continued Good AQI levels. Wednesday, a low-pressure system will approach from the west, producing moderate to strong southerly winds that will disperse pollutants in the Rochester area. Therefore, AQI levels will remain Good. Thursday, as the low-pressure system moves east, gusty westerly winds behind it will keep pollutants well dispersed in the Rochester area, yielding Good AQI levels. Friday, surface high pressure over the Dakotas will generate moderate northerly winds in the Rochester area, dispersing pollutants and keeping AQI levels Good.
