Forecast Discussion: Friday, July 29: Mostly cloudy skies will inhibit ozone formation in the Columbus region, and occasional thunderstorms will enhance mixing and dispersion. These conditions will yield Good AQI levels. Saturday, July 30: Light southwesterly winds will limit dispersion and gradually transport pollutants into central Ohio. Therefore, despite mostly cloudy skies reducing ozone formation, AQI levels will increase to low-Moderate. Sunday through Tuesday, increasing sunshine and temperatures in the mid- to upper-80s will enhance ozone formation in the Columbus region, and light and variable winds will reduce pollutant dispersion. These conditions will lead to Moderate AQI levels on all three days. Wednesday, an upper-level ridge of high pressure will build over central Ohio, reducing atmospheric mixing. In addition, partly sunny skies and warm temperatures will continue to support ozone formation. As a result, AQI levels will remain Moderate.
