Forecast Discussion: Today, moderate northerly winds will disperse pollutants and transport clean air into Rochester, yielding Good AQI levels. Tomorrow, surface high pressure moving through Minnesota will produce light southerly winds in Rochester, limiting pollutant dispersion and leading to low-Moderate AQI levels. Thursday, light southwesterly winds will gradually bring additional pollutants into Rochester, and partly to mostly sunny skies will aid ozone formation. As a result, AQI levels will be low-Moderate. Friday through Sunday, increasing clouds and scattered thunderstorms will reduce ozone formation. However, light to moderate southerly winds will continue to bring regional pollutants into Rochester, leading to Moderate AQI levels on all three days.
