Forecast Discussion: Saturday, September 20: Moderate to strong southerly winds ahead of an approaching cold front will transport moisture and regional pollutants into the Mahoning Valley, increasing particle production and resulting in Moderate AQI levels. Sunday, September 21: As the cold front moves through Ohio, moderate west-southwesterly winds will disperse pollutants, and mostly cloudy skies and widespread showers and thunderstorms will reduce ozone formation in the Youngstown-Warren region. These conditions will lower AQI levels to Good. Monday and Tuesday, light to moderate northwesterly winds behind the departing cold front will disperse pollutants and bring a clean air mass into northeastern Ohio. Therefore, AQI levels will remain Good on both days. Wednesday and Thursday, an upper-level ridge of high pressure over Ohio will reduce vertical mixing in the atmosphere and produce mostly sunny skies and warmer temperatures, aiding ozone formation. However, light to moderate east-southeasterly winds will help to disperse pollutants in the Mahoning Valley, keeping AQI levels Good on both days.
