Wednesday, July 31: Periods of sun and temperatures in the low-90s will promote ozone formation. Furthermore, aloft thin-density smoke may reach the surface, increasing particle levels and enhancing ozone development. Therefore, AQI levels will be low-Moderate. Thursday, August 1: Partly sunny skies early in the day and temperatures near 90F will continue to aid ozone production. However, periods of moderate southwesterly winds will aid dispersion, and scattered afternoon and evening thunderstorms will limit ozone formation. Thus, AQI levels will remain low-Moderate. Friday, partly cloudy skies and scattered thunderstorms will aid mixing and reduce ozone production. However, calm to light southerly winds associated with a passing surface low pressure system will hinder dispersion. Furthermore, these winds may carry thin-density smoke into central Ohio. As a result, AQI levels will remain low-Moderate. Saturday, winds will shift to northerly to northwesterly as the low departs Ohio. These winds will aid dispersion. Additionally, partly to mostly cloudy skies and scattered thunderstorms will continue to limit ozone formation. Therefore, AQI levels will be high-Good. Sunday and Monday, increasing sunshine and temperatures near 90F will enhance ozone formation. In addition, periods of calm winds each morning will allow pollutants and ozone precursors to accumulate. These conditions will yield low-Moderate AQI levels on both days.
