Forecast Discussion: Labor Day, September 1: Moderate southwesterly winds ahead of an approaching front will help disperse pollutants in central Ohio. Furthermore, mostly cloudy skies will suppress ozone formation, yielding Good AQI levels. Tuesday, September 2: 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, high pressure will strengthen over Ohio, reducing pollutant dispersion. In addition, sunny skies and warm temperatures will enhance ozone formation, yielding Moderate AQI levels. Thursday and Friday, southerly becoming southwesterly winds ahead of an approaching front will transport regional pollutants into central Ohio. Furthermore, sunny, warm conditions will enhance ozone formation, keeping AQI levels Moderate on both days. Saturday, a front will move through central Ohio, generating scattered thunderstorms and rain showers that will keep the atmosphere well mixed. These conditions will effectively disperse pollutants in Columbus. In addition, cloudy skies will suppress ozone formation, lowering AQI levels to Good.
