Forecast Discussion: Today, surface high pressure over the northern Plains will produce moderate northwesterly winds in the Rochester area. These winds will disperse pollutants, leading to Good AQI levels. Tomorrow, light and variable winds will inhibit pollutant dispersion in the Rochester area. Furthermore, an upper-level ridge of high pressure will limit vertical mixing in the atmosphere. As a result, AQI levels will be Moderate. Friday through Sunday, light southerly winds will limit pollutant dispersion and will gradually bring additional pollutants into the Rochester area. Therefore, AQI levels will be Moderate on all three days. Monday, a low-pressure system will move through Minnesota, enhancing vertical mixing in the atmosphere and shifting winds to northwesterly. These conditions will help to disperse pollutants; however, high pollutant carryover from previous days will keep AQI levels low-Moderate in Rochester.
