Saturday, January 10: A strong trough of low-pressure aloft over the western Great Lakes will enhance atmospheric mixing. In addition, despite light southerly winds hindering dispersion, regional pollutant carryover is low. As a result, AQI levels will be Good. Sunday, January 11: As the trough aloft moves across Ohio, it will continue to support atmospheric mixing throughout the day. Furthermore, gusty westerly to northwesterly winds will aid dispersion, leading to another day of Good AQI levels. Monday and Tuesday, gusty southwesterly winds will continue to promote low-level mixing and dispersion. However, these winds will gradually transport regional pollutants into northeastern Ohio. Therefore, AQI levels will be Good on Monday and high-Good on Tuesday. Wednesday, a deepening trough of low pressure aloft will enhance atmospheric mixing. In addition, moderate southwesterly winds and rain showers will aid dispersion as the next cold front approaches the Mahoning Valley. These conditions will result in Good AQI levels. Thursday, moderate northwesterly winds will promote dispersion and transport a clean air mass into Youngstown-Warren behind the departing front. As a result, AQI levels will be Good.
