Labor Day, September 7: Easterly to east-northeasterly winds will carry clean air into central Ohio as surface high pressure passes to the north. Therefore, AQI levels will be Good. Tuesday, September 8: Partly sunny skies and highs in the mid-80s will aid ozone formation. Additionally, light southerly to southwesterly winds will gradually carry regional pollutants into central Ohio. Thus, AQI levels will be high-Good. Wednesday, periods of sunshine and temperatures in the low-90s will enhance ozone production. Furthermore, southwesterly winds will carry additional pollutants into central Ohio. Therefore, AQI levels will be low-Moderate. Thursday, as a cold front traverses the Buckeye State, mixing will increase. In addition, clouds and scattered thunderstorms will reduce ozone formation. These conditions will yield Good AQI levels. Friday, as surface high pressure builds over the Ohio Valley, calm to light easterly winds will allow pollutants to accumulate. However, low carryover from the previous day will keep AQI levels Good. Saturday, light and variable winds will inhibit dispersion, while temperatures in the mid-80s will aid ozone formation. However, a passing trough of low pressure aloft will increase low-level mixing, resulting in high-Good AQI levels.
