Forecast Discussion: Thursday, September 18: Moisture associated with morning fog has enhanced particle formation in Youngstown-Warren. In addition, calm overnight winds have limited pollutant dispersion. Therefore, despite light to moderate northerly winds helping to disperse some pollutants in the afternoon, AQI levels will be Moderate. Friday, September 19: Light southeasterly winds will gradually transport additional pollutants into Youngstown-Warren, and mostly sunny skies will aid ozone formation. As a result, AQI levels will be low-Moderate. Saturday, southerly winds ahead of an approaching cold front will transport moisture and additional pollutants into the Mahoning Valley, increasing particle production. Furthermore, mostly sunny skies and warm afternoon temperatures will aid ozone formation. Therefore, AQI levels will be Moderate. Sunday, as the cold front moves through Ohio, winds shifting to northwesterly will disperse pollutants, and mostly cloudy skies and scattered showers will reduce ozone formation, yielding Good AQI levels. 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, keeping AQI levels Good on both days.
