Forecast Discussion: Wednesday, June 21: Warm, sunny conditions will enhance ozone formation, and west-southwesterly winds will transport regional pollutants into the Columbus area. As a result, AQI levels will be Moderate. Thursday, June 22: Partly to mostly sunny skies and temperatures near 90F will enhance ozone formation. In addition, light to moderate southwesterly winds will transport regional pollutants into the area, yielding Moderate AQI levels in the Columbus region. Friday, as a cold front moves through the Columbus region, scattered thunderstorms will limit ozone formation and enhance mixing in the atmosphere, lowering AQI levels to Good. Saturday through Monday, mostly sunny skies and warm temperatures will increase ozone production. Therefore, despite west-northwesterly winds transporting a cleaner air mass into the Columbus region, AQI levels will be low-Moderate on all three days.
