Forecast Discussion: Monday, August 31: Mostly sunny skies and above-normal temperatures will enhance ozone formation in the Buckeye State. Furthermore, light westerly winds will limit pollutant dispersion. These conditions will lead to Moderate AQI levels. 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 remain Moderate. Wednesday and Thursday, a surface high pressure system over Ohio will lead to light northerly winds in the Columbus area. Furthermore, mostly sunny skies and temperatures in the upper-80s will increase ozone production. As a result, AQI levels will be Moderate on both days. Friday and Saturday, an upper-level ridge of high pressure building over the northeast U.S. will limit mixing and increase ozone formation in central Ohio. Therefore, despite light northeasterly winds gradually transporting clean air into the region, AQI levels will remain Moderate on both days.
