Forecast Discussion: Sunday, August 30: Partly cloudy skies will limit ozone formation in the Columbus area, and scattered thunderstorms will enhance atmospheric mixing. Therefore, despite light southwesterly winds limiting pollutant dispersion, AQI levels will be Good. Monday, August 31: Clearing skies and above-normal temperatures will enhance ozone formation in the Buckeye State. Furthermore, light southwesterly winds will gradually transport regional pollutants into central Ohio. These conditions will lead to Moderate AQI levels. Tuesday and Wednesday, a surface high pressure system over Ohio will lead to calm winds in the Columbus area. Furthermore, mostly sunny skies and temperatures in the mid-80s will increase ozone production. As a result, AQI levels will be high-Moderate on both days. Thursday and Friday, light winds shifting to northeasterly will gradually transport clean air into central Ohio. However, continued warm temperatures and clear skies, combined with pollutant carryover from Tuesday and Wednesday, will result in Moderate AQI levels on both days.
