Forecast Discussion: Tuesday, September 1: Partly to mostly sunny skies and temperatures near 90F will increase ozone production, and light and variable winds will inhibit pollutant dispersion. Therefore, despite isolated thunderstorms increasing atmospheric mixing, AQI levels will be Moderate. Wednesday, September 2: Partly to mostly sunny skies and temperatures near 90F will continue to enhance ozone formation in central Ohio. In addition, light winds will reduce pollutant dispersion. As a result, AQI levels will remain Moderate. Thursday through Sunday, an upper-level ridge of high pressure over the eastern U.S. will limit mixing in the atmosphere, and light winds at the surface will reduce pollutant dispersion. Furthermore, sunny, warm conditions will increase ozone formation in central Ohio. Therefore, AQI levels will be Moderate on all four days.
