Forecast Discussion: Thursday, August 21: Mostly cloudy skies and scattered thunderstorms will inhibit ozone formation in the Columbus region. Therefore, despite light to moderate southwesterly winds bringing some pollutants into the area, AQI levels will be Good. Friday, August 22: Mostly cloudy skies and scattered thunderstorms will continue to limit ozone formation in central Ohio. However, light to moderate southerly winds will bring additional pollutants and moisture into the region, enhancing particle formation and resulting in low-Moderate AQI levels. Saturday through Tuesday, an upper-level ridge of high pressure building over the Midwest will produce partly sunny skies and warm temperatures in the Columbus region, aiding ozone formation. In addition, a humid air mass in place will continue to enhance particle production. These conditions, combined with pollutant carryover from day to day, will yield Moderate AQI levels on all four days.
