Forecast Discussion: Thursday, July 31: Light to moderate west-southwesterly winds will transport pollutants into the Columbus region. In addition, sunny skies and temperatures in the low-80s will enhance ozone production. As a result, AQI levels will be low-Moderate. Friday, August 1: Light southerly winds will gradually transport pollutants into Columbus, and sunny, warm conditions will continue to enhance ozone formation. Therefore, AQI levels will be Moderate. Saturday, increasing clouds and scattered showers will reduce ozone formation in central Ohio; however, light winds will continue to reduce pollutant dispersion, keeping AQI levels low-Moderate. Sunday and Monday, moderate northeasterly winds will effectively disperse pollutants in the Columbus region, yielding Good AQI levels on both days. Tuesday, light to moderate westerly winds will help to disperse in central Ohio. However, warm temperatures and mostly sunny skies will enhance ozone formation, leading to low-Moderate AQI levels.
