Forecast Discussion: Today, a low-pressure system moving through Minnesota will produce thunderstorms and mostly cloudy skies in Rochester, reducing the formation of ozone. In addition, moderate southeasterly winds will disperse pollutants. These weather conditions will result in Good AQI levels. Tomorrow, light and variable winds will limit pollutant dispersion, and partly sunny skies and warm temperatures will enhance ozone formation, leading to low-Moderate AQI levels. Saturday, moderate east-northeasterly winds and scattered thunderstorms will develop as a warm front approaches from the south, dispersing pollutants and lowering AQI levels to Good. Sunday, as the warm front moves into Rochester, moderate southeasterly winds and scattered thunderstorms will keep pollutants dispersed, resulting in Good AQI levels. Monday, as a cold front passes through Rochester, winds will shift to westerly, dispersing pollutants and bringing cooler, cleaner air into the region. Therefore, AQI levels will be Good. Tuesday, moderate southerly winds ahead of another approaching cold front will keep pollutants dispersed in the Rochester area, yielding Good AQI levels.
