Forecast Discussion: Wednesday, September 28: Mostly cloudy skies will limit ozone production in central Ohio, and scattered showers and thunderstorms will enhance vertical mixing in the atmosphere. As a result, AQI levels will be Good. Thursday, September 29: An upper-level trough of low-pressure over Ohio will enhance vertical mixing in the atmosphere, and cool temperatures will inhibit ozone formation in the Columbus area. Therefore, AQI levels will remain Good. Friday and Saturday, the upper-level trough will remain over the Great Lakes region, enhancing vertical mixing. Furthermore, continued cool temperatures and cloudy skies will inhibit ozone formation. These conditions will keep AQI levels Good on both days. Sunday and Monday, mostly sunny skies and warming temperatures will enhance ozone production. However, pollutant carryover from previous days will be low. Therefore, AQI levels will continue to be Good on both days.
