Forecast Discussion: Sunday, August 31: As a low-pressure system moves through the Great Lakes region, moderate southwesterly winds will transport regional pollutants into the Columbus area. However, mostly cloudy skies will reduce ozone formation and widespread showers and thunderstorms will keep the atmosphere well mixed, helping to disperse pollutants. Therefore, AQI levels will be Good. Labor Day, September 1: Moderate southwesterly winds ahead of a second low-pressure system will help disperse pollutants in central Ohio. Furthermore, mostly cloudy skies will continue to suppress ozone formation, keeping AQI levels Good. Tuesday, a front will move through the Buckeye State, increasing vertical mixing in the atmosphere and helping to disperse pollutants. In addition, cloudy skies and widespread rain showers will continue to inhibit ozone production. As a result, AQI levels will remain Good. Wednesday and Thursday, high pressure will strengthen over Ohio, reducing pollutant dispersion. In addition, sunny skies and warm temperatures will enhance ozone formation, yielding Moderate AQI levels on both days. Friday, southwesterly winds will develop ahead of an approaching front, transporting regional pollutants into central Ohio. Furthermore, sunny, warm conditions will enhance ozone formation, keeping AQI levels Moderate.
