Thursday, August 1: Partly sunny skies early in the day and temperatures near 90F will continue to aid ozone production. However, periods of moderate southerly to southwesterly winds will aid dispersion, and scattered afternoon and evening thunderstorms will limit ozone formation. Thus, AQI levels will remain low-Moderate. Friday, August 2: Scattered thunderstorms will aid mixing and reduce ozone production. However, light southwesterly winds associated with a passing surface low pressure system will hinder dispersion. Furthermore, these winds may carry thin-density Saharan dust into central Ohio, increasing particle levels. As a result, AQI levels will be Moderate. Saturday, mostly cloudy skies and scattered thunderstorms will continue to limit ozone formation. Additionally, winds will shift to northerly as the low departs Ohio, aiding dispersion. However, these winds will also transport thin-density smoke into central Ohio, keeping particle levels elevated. Therefore, AQI levels will be low-Moderate. Sunday, increasing sunshine and temperatures near 90F will enhance ozone formation in the Columbus region. In addition, light westerly winds will allow pollutants to build up. These conditions will lead to mid-Moderate AQI levels. Monday and Tuesday, as a frontal boundary stalls across northern Ohio, light southwesterly winds will transport pollutants into the Columbus region. Furthermore, mostly sunny skies will continue to support ozone production, leading to Moderate AQI levels on both days.
