Sunday, September 6 and Labor Day, September 7: As surface high pressure passes north of the Mahoning Valley, easterly to northeasterly winds will disperse pollutants and carry clean air into the region. Therefore, AQI levels will be Good on both days. Tuesday, as the surface high moves east of the state, winds will shift to southeasterly and transport regional pollutants into Youngstown-Warren. Furthermore, warmer temperatures will aid ozone development. Thus, AQI levels will increase to low-Moderate. Wednesday, gusty west-southwesterly winds will develop ahead of an approaching cold front, aiding dispersion. In addition, increasing clouds and scattered rain showers will limit ozone production, yielding high-Good AQI levels. Thursday and Friday, northwesterly winds behind the departing front will transport cleaner, cooler air into Youngstown-Warren. As a result, AQI levels will be Good on both days.
