Forecast Discussion: Saturday, August 29: Partly to mostly cloudy skies will limit ozone formation in the Mahoning Valley. However, light southwesterly winds will gradually transport regional pollutants into the area, enhancing ozone and particle production. As a result, AQI levels will be Moderate. Sunday, August 30: Mostly cloudy skies will limit ozone formation, and scattered thunderstorms will increase vertical mixing in the atmosphere. However, light southwesterly winds associated with surface high pressure over the eastern U.S. will continue to bring regional pollutants and moisture into Youngstown-Warren, increasing particle production. Therefore, AQI levels will remain Moderate. Monday and Tuesday, mostly sunny skies and temperatures in the mid- to upper-80s will enhance ozone production in the Mahoning Valley. Therefore, AQI levels will continue to be Moderate on both days. Wednesday, increasing clouds will inhibit ozone formation in the Youngstown-Warren region. However, light winds will limit pollutant dispersion. These conditions, combined with pollutant carryover from Monday and Tuesday, will result in Moderate AQI levels. Thursday, mostly sunny skies, warm temperatures, and light winds will keep AQI levels Moderate in Youngstown-Warren.
