Forecast Discussion: Monday, September 29: Light winds will limit pollutant dispersion in the Columbus region, and mostly sunny skies will aid ozone formation, yielding low-Moderate AQI levels. Tuesday, September 30: Light to moderate northeasterly winds will help to disperse pollutants in the Columbus region. Therefore, despite mostly sunny skies supporting ozone formation, AQI levels will be Good. Wednesday, calm to light winds will reduce pollutant dispersion in central Ohio, and mostly sunny skies and warm temperatures will enhance ozone formation. These conditions will lead to low-Moderate AQI levels. Thursday, southerly winds ahead of an approaching cold front will bring additional pollutants into central Ohio, yielding low-Moderate AQI levels. Friday, the cold front will move through the Buckeye State, enhancing atmospheric mixing and shifting winds to westerly in Columbus. These conditions will disperse pollutants, and mostly cloudy skies and scattered thunderstorms will reduce ozone formation, resulting in Good AQI levels. Saturday, moderate westerly winds will persist behind the departing cold front, effectively dispersing pollutants in central Ohio and yielding Good AQI levels.
