Forecast Discussion: Tuesday, July 29: Light to moderate northwesterly winds will effectively disperse pollutants in the Columbus region, and mostly cloudy skies will limit ozone formation, leading to Good AQI levels. Wednesday, July 30: Partly to mostly cloudy skies will continue to inhibit ozone formation in central Ohio, and light to moderate westerly winds will help to disperse pollutants. Therefore, AQI levels will be Good. Thursday and Friday, as weak surface high pressure moves over the region, lighter winds will reduce pollutant dispersion in Columbus. In addition, partly sunny skies with slightly warmer temperatures will enhance ozone production. As a result, AQI levels will be low-Moderate on both days. Saturday, increasing clouds and scattered showers will reduce ozone formation in central Ohio. In addition, as a cold front moves through the Buckeye State, winds will shift to northerly, helping to disperse pollutants. These conditions will lower AQI levels to Good. Sunday, light to moderate northeasterly winds will keep pollutants well dispersed in the Columbus region, yielding Good AQI levels.
