Forecast Discussion: Sunday, May 24: Surface high pressure over the Mid-Atlantic region will produce moderate southwesterly winds in central Ohio, transporting pollutants into the region. Furthermore, partly sunny skies and warm temperatures will enhance ozone formation. As a result, AQI levels will be Moderate. Memorial Day, May 25: Increasing cloud cover will reduce ozone formation in central Ohio, and moderate southerly winds will disperse pollutants, yielding Good AQI levels. Tuesday and Wednesday, mostly cloudy skies and scattered thunderstorms will limit ozone formation in the Columbus region. In addition, moderate and occasionally gusty southwesterly winds will disperse pollutants. Therefore, AQI levels will remain Good on both days. Thursday, a weak cold front moving through Ohio will enhance atmospheric mixing in the Columbus region, and winds shifting to westerly will disperse pollutants. As a result, AQI levels will be Good. Friday, light to moderate southerly winds will bring pollutants into central Ohio, and partly sunny skies and warm temperatures will aid ozone formation, resulting in low-Moderate AQI levels.
