Forecast Discussion: Monday, July 6: Partly to mostly sunny skies and warm temperatures will aid ozone formation in the Columbus region, and light southerly winds will limit pollutant dispersion. These conditions, combined with lingering smoke from Canadian wildfires, will lead to Moderate AQI levels. Tuesday, July 7: As a weak cold front approaches central Ohio, scattered showers and thunderstorms and moderate southwesterly winds will disperse some pollutants. However, these winds will also transport regional pollutants into the area. Therefore, AQI levels will remain Moderate. Wednesday, mostly cloudy skies and scattered showers and thunderstorms will reduce ozone formation in central Ohio. However, light winds will inhibit pollutant dispersion, keeping AQI levels Moderate. Thursday, as a low-pressure system quickly moves across northern Ohio, moderate southwesterly winds will develop in the Columbus region, transporting pollutants into the area and yielding low-Moderate AQI levels. Friday and Saturday, partly to mostly sunny skies and temperatures in the 80s will aid ozone formation, and light winds will limit pollutant dispersion. As a result, AQI levels will be Moderate on both days.
