Forecast Discussion: Wednesday, July 23: Light to moderate westerly winds will develop as a cold front gradually moves through the Buckeye State, helping to disperse pollutants. Furthermore, mostly cloudy skies will inhibit ozone formation. As a result, AQI levels will be Good. Thursday, July 24: Moderate north-northwesterly winds behind the departing cold front will effectively disperse pollutants and bring a cleaner air mass into central Ohio, keeping AQI levels Good. Friday, winds will diminish as surface high pressure moves across northern Ohio, reducing pollutant dispersion. In addition, sunny and warm conditions will support ozone formation in the Columbus area. Therefore, AQI levels will be Moderate. Saturday and Sunday, light southerly winds will develop ahead of an approaching cold front, transporting additional pollutants into central Ohio. Furthermore, mostly sunny skies and warmer temperatures will increase ozone formation, keeping AQI levels Moderate on both days. Monday, a cold front will move through Ohio, increasing vertical mixing in the atmosphere and shifting winds to west-northwesterly. These winds will help to disperse pollutants. In addition, widespread showers and thunderstorms will reduce ozone formation. As a result, AQI levels will be Good.
