Forecast Discussion: Sunday, April 20: Southerly winds ahead of an approaching low-pressure system will transport pollutants and moisture into Youngstown-Warren, enhancing particle production. As a result, AQI levels will be Moderate. Monday, April 21: Light to moderate southwesterly winds will continue to bring regional pollutants and humid air into northeastern Ohio. As a result, AQI levels will remain Moderate. Tuesday and Wednesday, mostly cloudy skies will reduce ozone formation. In addition, the low-pressure system will move through Ohio and depart to the east, generating moderate northwesterly winds in the Mahoning Valley. These winds will effectively disperse pollutants, yielding Good AQI levels on both days. Thursday, as another low-pressure system approaches Ohio from the west, moderate southerly winds will transport pollutants and moisture into Youngstown-Warren, aiding particle formation. Therefore, AQI levels will be low-Moderate. Friday, the low-pressure system will move through Ohio, shifting winds to westerly and helping to disperse pollutants in the Mahoning Valley. In addition, mostly cloudy skies will reduce ozone formation, leading to Good AQI levels.
