Forecast Discussion: Today, strong and occasionally gusty west-northwesterly winds will effectively disperse pollutants in the Rochester area, yielding Good AQI levels. Tomorrow, moderate west-northwesterly winds will persist through the morning hours, continuing to disperse pollutants in the Rochester region. Therefore, despite southerly winds developing in the afternoon, AQI levels will remain Good. Wednesday, a low-pressure system will move through southern Minnesota, shifting winds to northerly. These winds will bring a cold, clean air mass into Rochester, yielding Good AQI levels. Thanksgiving Day, moderate northwesterly winds will persist behind the departing low-pressure system, continuing to bring cold, clean air into the region. As a result, AQI levels will remain Good. Friday, as a low-pressure system approaches from the west, light southerly winds will develop in Rochester, 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. These conditions will disperse pollutants in Rochester and lower AQI levels to Good.
