Forecast Discussion: Thursday, September 18: Humid air has enhanced particle production this morning in the Columbus region. However, partly cloudy skies will limit ozone formation, and light to moderate northerly winds will disperse pollutants throughout the afternoon. Therefore, AQI levels will be low-Moderate. Friday, September 19: Light easterly winds will reduce pollutant dispersion and gradually transport additional 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 and Tuesday, light to moderate northwesterly winds will disperse pollutants and bring a clean air mass into central Ohio, yielding Good AQI levels on both days.
