The highest AQ index in Ohio (as of 15:00 EDT) is currently the Toledo area. Ozone (OZONE) is measuring at 84 (Moderate). This means air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Over the next few days, the highest Ozone (OZONE) will be in the Youngstown area. It is forecasted to be Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.
Wednesday, July 8: Increasing sunshine and temperatures warming into the mid-80s will support ozone formation. Additionally, calm to light winds throughout the day will limit pollutant dispersion, leading to low-Moderate AQI levels. Thursday, July 9: West-southwesterly winds will transport regional pollutants into the Mahoning Valley, and warm temperatures with partly to mostly sunny skies will support ozone formation. However, isolated afternoon showers will limit ozone production. Therefore, AQI levels will remain low-Moderate. Friday, as a cold front moves across the region, mostly cloudy skies and widespread rain showers will inhibit ozone production. Additionally, westerly to northwesterly winds behind the departing front will gradually carry cleaner air into Youngstown-Warren, lowering AQI levels to high-Good. Saturday and Sunday, increasing sunshine will enhance ozone formation in the Mahoning Valley. Additionally, light northeasterly winds throughout most of the period will reduce pollutant dispersion. Thus, AQI levels will be low-Moderate on both days. Monday, as an upper-level ridge of high pressure builds across the Great Lakes, mostly sunny skies and temperatures warming into the upper-80s will increase ozone production in Youngstown-Warren. Furthermore, light and variable winds will limit mixing and dispersion, leading to mid-Moderate AQI levels.
