Forecast Discussion: Wednesday, August 27: As a cold front moves through northeastern Ohio, mostly cloudy skies will inhibit ozone formation. However, moisture associated with areas of fog this morning has enhanced particle formation. As a result, AQI levels will be low-Moderate. Thursday, August 28: Surface high pressure over Michigan will produce light to moderate northerly winds in Youngstown-Warren, dispersing pollutants. However, mostly sunny skies and warm afternoon temperatures will enhance ozone formation, resulting in low-Moderate AQI levels. Friday and Saturday, southerly winds will develop as a low-pressure system approaches from the west, transporting regional moisture and pollutants into Youngstown-Warren. In addition, mostly sunny and warm conditions will continue to support ozone formation, keeping AQI levels Moderate on both days. Sunday, as the low-pressure system moves through the Great Lakes region, moderate southwesterly winds will help to disperse pollutants in Youngstown-Warren. In addition, cloudy skies and scattered thunderstorms will reduce ozone formation, lowering AQI levels to Good. Labor Day, as a second low-pressure system approaches from the west, moderate southerly winds ahead of it will bring pollutants into the Mahoning Valley, and partly sunny skies and warm temperatures will aid ozone formation. As a result, AQI levels will be Moderate.
