Forecast Discussion: Friday, May 29: Light to moderate southerly winds ahead of an approaching cold front will bring pollutants into central Ohio, and partly sunny skies and warm temperatures will support ozone formation. Therefore, AQI levels will be low-Moderate. Saturday, May 30: As a cold front moves into Ohio, moderate southwesterly winds will disperse pollutants and bring a cleaner air mass into the Columbus region. In addition, mostly cloudy skies and thunderstorms will reduce ozone production. As a result, AQI levels will be Good. Sunday and Monday, mostly cloudy skies and scattered rain showers will continue to limit ozone formation, and moderate northeasterly winds will keep pollutants well dispersed in central Ohio. Therefore, AQI levels will be Good on both days. Tuesday and Wednesday, an upper-level ridge of high pressure will build over Ohio, reducing mixing in the atmosphere and producing mostly sunny skies and warm temperatures. These conditions will increase ozone production, and lighter winds will limit pollutant dispersion. As a result, AQI levels will be Moderate on both days.
