The highest AQ index in Ohio (as of 23:00 EDT) is currently the Dayton area. Ozone (OZONE) is measuring at 38 (Good). This means air quality is satisfactory, and air pollution poses little or no risk.
Over the next few days, the highest Ozone (OZONE) will be in the Columbus 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.
Saturday, April 18 through Monday, April 20: A passing cold front will enhance low-level mixing and dispersion, and westerly to northwesterly winds behind the front will transport cleaner, cooler air into the Columbus region. These conditions will yield Good AQI levels on all three days. Tuesday, mostly sunny skies will aid ozone production over central Ohio. In addition, surface high pressure east of the state will generate moderate southerly to southwesterly winds. While these winds will bring pollutants into the Columbus region, pollutant carryover from the previous days will be low. As a result, AQI levels will be high-Good. Wednesday, as a weak cold front passes southward through central Ohio, light westerly winds will develop in the afternoon, gradually transporting cleaner air into the region and leading to Good AQI levels. Thursday, light southwesterly winds will limit dispersion and gradually carry pollutants into the Columbus region. Furthermore, mostly sunny skies and temperatures near 80F will enhance ozone formation. As a result, AQI levels will be low-Moderate.
