Forecast Discussion: Sunday, July 5: Lingering smoke from fireworks displays and Canadian fires has lead to elevated particle concentrations in the Columbus area. Furthermore, partly sunny skies and warm temperatures will support ozone formation, and light easterly winds will limit pollutant dispersion. As a result, AQI levels will be Moderate. Monday, July 6: Light southerly winds will develop as a weak frontal boundary approaches the Buckeye State from the northwest, limiting dispersion and slowly bringing regional pollutants into the Columbus area. In addition, partly sunny skies and warm temperatures will continue to aid ozone formation, keeping AQI levels Moderate. Tuesday, as the front moves into central Ohio, enhanced atmospheric mixing associated with scattered showers and thunderstorms and moderate southerly winds will disperse some pollutants. However, partly sunny skies and warm temperatures will continue to support ozone formation. Therefore, AQI levels will remain Moderate. Wednesday through Friday, mostly cloudy skies will reduce ozone formation in the Columbus area. However, light winds will limit pollutant dispersion. These conditions, combined with pollutant carryover from day to day, will lead to Moderate AQI levels on all three days.
