Saturday, March 28: Northwesterly winds will disperse pollutants and transport clean, cool air into Youngstown-Warren behind a departing front. Therefore, AQI levels will be Good. Sunday, March 29 and Monday, March 30: Surface high pressure east of the state will produce periods of moderate southwesterly winds. While these winds will aid dispersion, they will also carry regional pollutants and smoke from agricultural fires in the southeastern U.S. into the Mahoning Valley. Thus, AQI levels will increase to low-Moderate on both days. Tuesday, as a cold front approaches from the northwest, strengthening southwesterly winds and rain showers will enhance dispersion, yielding high-Good AQI levels. Wednesday, northerly to northeasterly winds behind the departing cold front will usher cleaner, cooler air into Youngstown-Warren, resulting in Good AQI levels. Thursday, moderate east-southeasterly winds will develop as a low pressure system approaches from the west, keeping pollutants well dispersed and leading to continued Good AQI levels.
