Forecast Discussion: Monday, August 29: Mostly sunny skies and warm temperatures will enhance ozone formation in the Columbus region. Therefore, despite light to moderate northeasterly winds aiding pollutant dispersion, AQI levels will be low-Moderate. Tuesday, August 30: As a surface high pressure moves over Ohio, lighter winds will limit pollutant dispersion, and mostly sunny skies and warm temperatures will continue to enhance ozone formation. As a result, AQI levels will remain low-Moderate. Wednesday, as a cold front passes through the Columbus area, light to moderate north-northwesterly winds will aid pollutant dispersion. In addition, partly to mostly cloudy skies and scattered thunderstorms will inhibit ozone formation. Therefore, despite temperatures in the mid-80s aiding ozone production, AQI levels will lower to Good. Thursday through Saturday, light to moderate north-northeasterly winds will effectively disperse pollutants. These winds will also bring cooler air into the region, limiting ozone formation. Therefore, AQI levels will be Good on all three days.
