Forecast Discussion: Sunday, April 20: Moderate southerly winds ahead of an approaching low-pressure system will gradually transport regional pollutants and moisture into the Columbus region, enhancing particle production. Therefore, AQI levels will be Moderate. Monday, April 21: Light to moderate southerly winds will bring additional pollutants and humid air into central Ohio, aiding particle formation. As a result, AQI levels will remain Moderate. Tuesday, the low-pressure system will move through Ohio early in the day, shifting winds to northwesterly in Columbus. These winds will disperse pollutants, lowering AQI levels to Good. Wednesday, moderate northwesterly winds behind the departing low-pressure system will continue to disperse pollutants in central Ohio. As a result, AQI levels will be Good. Thursday, moderate southerly winds ahead of an approaching cold front will transport regional pollutants into Columbus. In addition, mostly sunny skies will aid ozone formation. Therefore, AQI levels will be low-Moderate. Friday, the cold front will move through central Ohio and depart eastward, shifting winds to westerly and dispersing pollutants. In addition, overcast skies will limit ozone production, leading to Good AQI levels.
