Forecast Discussion: Wednesday, April 23: Moderate northwesterly winds behind a departing cold front will effectively disperse pollutants in the Columbus area, resulting in Good AQI levels. Thursday, April 24: Moderate south-southeasterly winds will develop ahead of an approaching low pressure system, bringing regional pollutants into central Ohio. In addition, mostly sunny skies and warm temperatures will aid ozone formation, yielding low-Moderate AQI levels. Friday, as the low-pressure system moves through the Great Lakes, gusty west-southwesterly winds will help to disperse pollutants in central Ohio. Furthermore, mostly cloudy skies and scattered showers will reduce ozone formation. As a result, AQI levels will be Good. Saturday and Sunday, moderate northerly winds behind the departing low-pressure system will disperse pollutants and transport clean, cool air into the Columbus area. As a result, AQI levels will be Good on both days. Monday, 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.
