Forecast Discussion: Monday, September 26: Moderate and gusty westerly winds behind a departing cold front will effectively disperse pollutants in the Columbus area. In addition, mostly cloudy skies will limit ozone formation, and scattered thunderstorms will keep the low levels of the atmosphere well mixed. As a result, AQI levels will be Good. Tuesday, September 27: Cool temperatures will inhibit ozone formation, and moderate and gusty southwesterly winds will effectively disperse pollutants. Therefore, AQI levels will remain Good. Wednesday through Saturday, an upper-level trough of low pressure over the Great Lakes region will enhance vertical mixing, and cooler temperatures will inhibit ozone formation in central Ohio. These conditions will keep AQI levels Good on all four days.
