Forecast Discussion: Tuesday, August 30: As a surface high pressure moves over central Ohio, calm winds will limit pollutant dispersion, and mostly sunny skies and temperatures approaching 90F will enhance ozone formation. As a result, AQI levels will be Moderate. Wednesday, August 31: As a cold front passes through the Columbus area, light to moderate northwesterly winds will aid pollutant dispersion. In addition, partly to mostly cloudy skies and scattered thunderstorms will inhibit ozone formation. Therefore, AQI levels will lower to Good. Thursday through Saturday, light to moderate northerly winds will effectively disperse pollutants and bring a cooler air mass into the region, limiting ozone formation. As a result, AQI levels will be Good on all three days. Sunday, an upper-level ridge of high pressure will build over Ohio, inhibiting vertical mixing. In addition, warmer temperatures and sunny skies will aid ozone production. These conditions will lead to Moderate AQI levels.
