Forecast Discussion: Today, moderate west-northwesterly winds through the morning hours will disperse pollutants in the Rochester region. Therefore, despite southerly winds developing in the afternoon, AQI levels will be Good. Tomorrow, a low-pressure system will move through Iowa, shifting winds to northerly in southeastern Minnesota. These winds will bring a cold, clean air mass into the region, yielding Good AQI levels. Thanksgiving Day, light to moderate northwesterly winds will persist behind the departing low-pressure system, continuing to transport cold, clean air into the Rochester area. As a result, AQI levels will remain Good. Friday, as another low-pressure system approaches from the west, light southerly winds will develop in southeastern Minnesota, transporting regional pollutants into the area. Therefore, AQI levels will be low-Moderate. Saturday, the low-pressure system will move through Minnesota, enhancing mixing in the atmosphere and shifting winds to north-northwesterly. These weather conditions will effectively disperse pollutants in Rochester, lowering AQI levels to Good. Sunday, moderate north-northwesterly winds will persist behind the departing low-pressure system, continuing to disperse pollutants and yielding Good AQI levels.
