Forecast Discussion: Today, partly sunny skies and warm temperatures will enhance ozone formation in Rochester. However, light to moderate southerly winds will aid pollutant dispersion, and showers and thunderstorms will increase atmospheric mixing. As a result, AQI levels will be Good. Tomorrow, a cold front will pass through southern Minnesota, bringing a clean air mass into the region and yielding Good AQI levels. Wednesday, light to moderate northerly winds behind the departing front will aid pollutant dispersion, and cooler temperatures will limit ozone formation. Therefore, AQI levels will remain Good. Thursday and Friday, as surface high pressure moves through the Great Lakes, moderate easterly to southeasterly winds will effectively disperse pollutants in southern Minnesota. In addition, cooler temperatures will continue to limit ozone formation. These conditions will keep AQI levels Good on both days. Saturday, a low pressure system approaching Minnesota will generate moderate to strong southerly winds in Rochester, effectively dispersing pollutants and yielding Good AQI levels.
