Forecast Discussion: Tuesday, July 29: Light to moderate west-northwesterly winds will disperse pollutants in Youngstown-Warren, and overcast skies will inhibit ozone formation. As a result, AQI levels will be Good. Wednesday, July 30: Light to moderate westerly winds will keep pollutants well dispersed in the Mahoning Valley, and mostly cloudy skies will continue to limit ozone formation. Therefore, AQI levels will remain Good. Thursday, as surface high pressure moves over the eastern Great Lakes, light to moderate southwesterly winds will gradually transport pollutants into Youngstown-Warren. However, low pollutant carryover from Wednesday will keep AQI levels Good. Friday, light winds will reduce pollutant dispersion in the Mahoning Valley, and partly sunny skies will aid ozone formation. These conditions will result in low-Moderate AQI levels. Saturday, as a cold front moves through Ohio, mostly cloudy skies and scattered thunderstorms will reduce ozone formation, and winds shifting to northerly will disperse pollutants. As a result, AQI levels will be Good. Sunday, surface high pressure building over the Great Lakes will produce moderate northeasterly winds in Youngstown-Warren, dispersing pollutants and keeping AQI levels Good.
