Forecast Discussion: Wednesday, September 17: Light winds will reduce pollutant dispersion in central Ohio. However, mostly cloudy skies will limit ozone formation, and pollutant carryover from previous days will be low. Therefore, AQI levels will be Good. Thursday, September 18: Surface high pressure over the Great Lakes will produce light to moderate northeasterly winds in the Columbus region, dispersing pollutants and keeping AQI levels Good. Friday, light southeasterly winds will reduce pollutant dispersion and gradually transport pollutants into central Ohio. In addition, mostly sunny skies will aid ozone formation. As a result, AQI levels will be low-Moderate. Saturday, southerly winds ahead of an approaching cold front will transport additional pollutants into the Columbus region, and sunny, warmer conditions will continue to support ozone formation. Therefore, AQI levels will remain Moderate. Sunday, the cold front will move through the Buckeye State, shifting winds to northwesterly and dispersing pollutants. In addition, mostly cloudy skies and scattered showers will reduce ozone formation, lowering AQI levels to Good. Monday, moderate northwesterly winds will disperse pollutants and bring a clean air mass into central Ohio, yielding Good AQI levels.
