Forecast Discussion: Tuesday, August 4: Moderate westerly winds behind a departing cold front will disperse pollutants in the Mahoning Valley, yielding Good AQI levels. Wednesday, August 5: Light to moderate west-northwesterly winds will gradually bring a clean, dry air mass into Youngstown-Warren. Therefore, despite mostly sunny skies aiding ozone formation, AQI levels will remain Good. Thursday, light winds will reduce pollutant dispersion in Youngstown-Warren; however, partly cloudy skies will reduce ozone formation, and pollutant carryover from the previous days will be low. These conditions will keep AQI levels Good. Friday and Saturday, surface high pressure to the north will generate light to moderate northeasterly winds in Youngstown-Warren, transporting clean air into the region and yielding Good AQI levels. Sunday, light winds will reduce pollutant dispersion, and sunny, warm conditions will enhance ozone formation. As a result, AQI levels will be low-Moderate.
