Forecast Discussion: Saturday, May 23: As surface high pressure moves over the Ohio River Valley, light to moderate southwesterly winds will transport pollutants into the Columbus region, and sunny skies will increase ozone formation. Therefore, AQI levels will be low-Moderate. Sunday, May 24: Surface high pressure over the Mid-Atlantic region will produce moderate southwesterly winds in central Ohio, transporting additional pollutants into the region. Furthermore, partly sunny skies will continue to support ozone formation. As a result, AQI levels will remain Moderate. Memorial Day through Thursday, mostly cloudy skies and scattered thunderstorms will limit ozone formation in central Ohio. However, southwesterly winds will continue to bring pollutants into the region, keeping AQI levels low-Moderate on all four days.
