Monday, November 4: Moderate southerly winds will aid dispersion throughout the day in Youngstown-Warren, while mild temperatures support low-level mixing in the afternoon. As a result, AQI levels will be high-Good. Tuesday, November 5: As a cold front approaches the Mahoning Valley, atmospheric mixing will increase, while moderate and gusty southerly winds continue to aid pollutant dispersion. Therefore, AQI levels will be Good. Wednesday, the cold front will push through northeastern Ohio during the morning, with periods of rain supporting dispersion. In addition, northwesterly to northerly winds will usher a clean air mass into the Mahoning Valley behind the front, keeping AQI levels Good. Thursday, low-level mixing will be reduced as a morning temperature inversion develops in Youngstown-Warren. In addition, light northerly winds throughout the day will hinder dispersion. However, low pollutant carryover from the previous days will allow AQI levels to remain high-Good. Friday, moderate west-northwesterly winds will promote low-level mixing and dispersion, keeping AQI levels Good. Saturday, as a surface high pressure system moves across northeastern Ohio, calm winds and a morning temperature inversion will limit dispersion and confine pollutants near the surface. In addition, a ridge of high pressure aloft will hinder atmospheric mixing, leading to low-Moderate AQI levels.
