Forecast Discussion: Saturday, April 25: Moderate easterly winds will develop ahead of an approaching low-pressure system, effectively dispersing pollutants in central Ohio. In addition, cloudy skies and rain showers will limit ozone formation. As a result, AQI levels will be Good. Sunday, April 26: As the low-pressure system passes south of Ohio, moderate northerly winds will develop in Columbus. These winds will transport a clean air mass into the region, yielding Good AQI levels. Monday and Tuesday, light to moderate north-northwesterly winds will disperse pollutants and bring a clean air mass into the Columbus region. In addition, partly cloudy skies will limit ozone formation. As a result, AQI levels will remain Good on both days. Wednesday and Thursday, lighter northwesterly winds will limit pollutant dispersion in central Ohio. However, low pollutant carryover from day to day will keep AQI levels Good on both days.
