Forecast Discussion: Thursday, April 24: Moderate south-southeasterly winds ahead of an approaching cold front will disperse pollutants in central Ohio. Therefore, despite mostly sunny skies aiding ozone formation, AQI levels will be Good. Friday, April 25: As the cold front moves through Ohio, gusty winds will disperse pollutants in the Columbus area. Furthermore, mostly cloudy skies and scattered showers will limit ozone formation. As a result, AQI levels will be Good. Saturday, moderate northwesterly winds behind the departing cold front will disperse pollutants in the Columbus area, keeping AQI levels Good. Sunday, moderate northeasterly winds will keep pollutants well dispersed in central Ohio, yielding Good AQI levels. Monday and Tuesday, mostly cloudy skies ahead of an approaching warm front will limit ozone formation in central Ohio, and moderate easterly winds will disperse pollutants. Therefore, AQI levels will remain Good on both days.
