Forecast Discussion: Labor Day, September 1: As a front approaches from the west, moderate southerly winds ahead of it will disperse pollutants in the Mahoning Valley, and mostly cloudy skies will inhibit ozone formation. Therefore, AQI levels will be Good. Tuesday, September 2: The front will move through Youngstown-Warren, increasing vertical mixing in the atmosphere and generating moderate southwesterly winds that will disperse pollutants. In addition, mostly cloudy skies and widespread rain showers will inhibit ozone formation, keeping AQI levels Good. Wednesday and Thursday, surface high pressure will strengthen over the Ohio River Valley, reducing pollutant dispersion in Youngstown-Warren. In addition, mostly sunny skies and warm temperatures will enhance ozone formation, yielding Moderate AQI levels on both days. Friday, moderate southwesterly winds ahead of an approaching low-pressure system will transport regional pollutants into Youngstown-Warren, and sunny, warm conditions will enhance ozone formation. As a result, AQI levels will remain Moderate. Saturday, a cold front will pass through Ohio, generating scattered showers and thunderstorms, keeping the atmosphere well mixed. In addition, cloudy skies will suppress ozone formation and northerly winds will transport a cleaner air mass into northeastern Ohio, lowering AQI levels to Good.
