Forecast Discussion: Today, light to moderate southwesterly winds will develop as a weak surface low-pressure system moves into northern Minnesota, dispersing pollutants and yielding Good AQI levels. Tomorrow, 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 Rochester, yielding Good AQI levels. Friday, moderate northerly winds will transport clean air into the Rochester area. As a result, AQI levels will remain Good. Saturday, surface high pressure southeast of Minnesota will generate moderate westerly winds in Rochester, effectively dispersing pollutants and keeping AQI levels Good.
