Forecast Discussion: Thursday, May 28: A weak cold front moving through Ohio early in the day will enhance atmospheric mixing in the Columbus region. However, light easterly winds will reduce pollutant dispersion. In addition, partly to mostly sunny skies and warm temperatures will increase ozone formation. As a result, AQI levels will be low-Moderate. Friday, May 29: Light to moderate southerly winds ahead of an approaching cold front will bring additional pollutants into central Ohio, and mostly sunny skies and warm temperatures will continue to support ozone formation. Therefore, AQI levels will be Moderate. Saturday, as the cold front moves through Ohio and departs to the east, moderate southwesterly winds will disperse pollutants and bring a cleaner air mass into the Columbus region, leading to Good AQI levels. Sunday through Tuesday, mostly cloudy skies and rain showers will limit ozone formation, and moderate northeasterly to easterly winds will keep pollutants well dispersed in central Ohio. Therefore, AQI levels will be Good on all three days.
