Forecast Discussion: Tuesday, September 1: Mostly sunny skies and temperatures nearing 90F will increase ozone production, and light westerly winds will limit pollutant dispersion in Youngstown-Warren. Therefore, AQI levels will be high-Moderate. Wednesday, September 2: Light westerly winds will inhibit pollutant dispersion, and partly to mostly sunny skies will continue to support ozone production. Therefore, despite isolated thunderstorms enhancing atmospheric mixing, AQI levels will continue to be Moderate. Thursday through Sunday, a strengthening upper-level ridge of high pressure will increase stability across the Mahoning Valley, reducing mixing and dispersion. Additionally, sunny skies and very warm temperatures will enhance ozone formation. Therefore, AQI levels will remain Moderate in Youngstown-Warren on all four days.
