Forecast Discussion: Saturday, September 24: Partly to mostly cloudy skies will reduce ozone formation in central Ohio, and light to moderate northerly winds will bring a cleaner air mass into the region. Therefore, despite pollutant carryover from Friday and morning fog and mist enhancing particle concentrations, AQI levels will be Good. Sunday, September 25: A surface high pressure system over the northern Great Lakes will generate light northeasterly winds in central Ohio, dispersing pollutants and continuing to transport cleaner air into the region. Therefore, AQI levels will remain Good. Monday, moderate and gusty southwesterly winds ahead of an approaching low-pressure system will effectively disperse pollutants. In addition, mostly cloudy skies will limit ozone formation, and scattered thunderstorms will keep the low levels of the atmosphere well mixed. As a result, AQI levels will remain Good. Tuesday through Thursday, an upper-level trough of low pressure over the Great Lakes region will enhance vertical mixing, and cooler temperatures will inhibit ozone formation. These conditions will keep AQI levels Good on all three days.
