Thursday, December 4: Moderate northwesterly winds will carry clean and colder air into the region in the afternoon. Therefore, despite calm to light evening winds allowing pollutants to accumulate, AQI levels will be high-Good. Friday, December 5 and Saturday, December 6: A pair of upper-level low pressure systems passing north of the region will aid mixing. However, southwesterly surface winds each day will transport regional pollutants into Youngstown-Warren. Additionally, morning inversions will trap pollutants near the ground. Thus, AQI levels will increase to low-Moderate on both days. Sunday, calm to light westerly to southwesterly winds throughout the day will inhibit dispersion, allowing pollutants to accumulate across the Mahoning Valley. Therefore, despite a passing aloft trough of low pressure aiding mixing, AQI levels will remain low-Moderate. Monday, surface high pressure over the Great Lakes will generate light to moderate northerly winds throughout much of the day. These winds will bring cleaner air into the region, yielding high-Good AQI levels. Tuesday, mixing will be enhanced as a cold front traverses Ohio. At the surface, moderate southwesterly winds will aid dispersion. These conditions will keep AQI levels high-Good.
