Forecast Discussion: Monday, May 4: Moderate southwesterly winds will transport regional pollutants and moisture into the Columbus area, enhancing particle formation. In addition, warm temperatures and partly to mostly sunny skies will support ozone formation. As a result, AQI levels will be low-Moderate. Tuesday, May 5: As a weak cold front moves into central Ohio, scattered thunderstorms will enhance atmospheric mixing, and increasing clouds will reduce ozone formation. However, pollutant carryover from previous days will keep AQI levels low-Moderate. Wednesday through Friday, light winds will reduce pollutant dispersion in the Columbus region. Furthermore, warmer temperatures and partly to mostly sunny skies will support ozone formation. These conditions, combined with day-to-day pollutant carryover, will lead to Moderate AQI levels on all three days. Saturday, increasing clouds and cooler temperatures will reduce ozone formation in central Ohio. However, southerly winds will gradually transport additional pollutants into the area, supporting particle production and keeping AQI levels Moderate.
