Forecast Discussion: Wednesday, April 23: Mostly cloudy skies and cool temperatures will limit ozone formation in Youngstown-Warren, and moderate to strong northwesterly winds will effectively disperse pollutants, yielding Good AQI levels. Thursday, April 24: Surface high pressure moving east across northeastern Ohio will cause winds to diminish and shift to southeasterly, gradually bringing warmer, more polluted air into the Mahoning Valley. As a result, AQI levels will be low-Moderate. Friday, a cold front moving through Ohio will enhance atmospheric mixing and shift winds to westerly in Youngstown-Warren, dispersing pollutants. Furthermore, mostly cloudy skies and scattered showers will inhibit ozone formation. Therefore, AQI levels will remain Good. Saturday and Sunday, moderate north-northwesterly winds behind the departing low-pressure system will keep pollutants well dispersed in Youngstown-Warren, resulting in Good AQI levels on both days. Monday, moderate easterly winds will disperse pollutants in the Mahoning Valley, and mostly cloudy skies will limit ozone formation, keeping AQI levels Good.
