Forecast Discussion: Sunday, May 19: Light to moderate southerly winds will transport moisture and regional pollutants into central Ohio, enhancing particle formation. Therefore, despite partly cloudy skies and scattered thunderstorms inhibiting ozone production, AQI levels will be low-Moderate for particles. Monday, May 20: Lighter southerly winds will continue to gradually transport regional pollutants into Columbus. In addition, very humid air will enhance particle production. These conditions, combined with pollutant carryover from previous days, will lead to Moderate AQI levels. Tuesday through Thursday, as a low-pressure system gradually approaches and moves through Ohio, generally southerly winds will transport additional regional pollutants and moisture into the Columbus region, enhancing particle production. Despite increasing clouds limiting ozone formation, AQI levels will be Moderate for particles on all three days. Friday, winds will shift to northwesterly behind the departing low-pressure system, transporting cleaner, drier air into the Columbus region and dispersing pollutants. As a result, AQI levels will be Good.
