Forecast Discussion: Today, increasing sunshine in the afternoon will enhance ozone formation in Rochester. However, light northeasterly winds will disperse pollutants and bring clean air into the area. Therefore, AQI levels will be Good. Tomorrow, an upper-level ridge of high pressure will build over Minnesota, reducing atmospheric mixing. Furthermore, light to moderate southerly winds will gradually transport pollutants into Rochester, and smoke from wildfires in the Pacific Northwest may impact the region, increasing particle and ozone levels. As a result, AQI levels will be Moderate. Monday through Thursday, partly to mostly sunny skies and temperatures in the low-80s will enhance ozone production. Furthermore, moderate southerly winds will continue to transport pollutants into Rochester. Therefore, despite a weakening upper-level ridge increasing vertical mixing in the atmosphere, AQI levels will be low-Moderate on all four days.
