Forecast Discussion: Tuesday, August 23: An upper-level ridge of high pressure over the eastern U.S. will inhibit vertical mixing, and sunny skies and temperatures in the low-80s will enhance ozone formation in the Columbus region. As a result, AQI levels will be low-Moderate. Wednesday, August 24: Sunny and warm conditions will continue to support ozone formation in central Ohio, and light to moderate south-southeasterly winds will bring regional pollutants into the area. Therefore, AQI levels will remain Moderate. Thursday, as a front moves through central Ohio, increasing clouds and thunderstorms will reduce ozone formation, and moderate westerly winds will disperse pollutants. Therefore, AQI levels will lower to Good. Friday, mostly sunny skies will increase ozone formation in the Columbus area. However, light northerly winds will transport clean air into the region, leading to Good AQI levels. Saturday and Sunday, sunny and warm conditions will continue to aid ozone production in central Ohio, leading to low-Moderate AQI levels on both days.
