Air Quality Index for Ohio
The highest AQ index in Ohio (as of 23:00 EDT) is currently the Dayton area. Particle Pollution (PM2.5) is measuring at 61 (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 Particle Pollution (PM2.5) will be in the Columbus area. It is forecasted to be Good, meaning air quality is satisfactory, and air pollution poses little or no risk.
Tuesday, April 8: As a cold front departs the Buckeye State, moderate northwesterly winds will effectively disperse pollutants, yielding Good AQI levels. Wednesday, April 9: Surface high pressure east of Ohio will produce light and variable winds in the Columbus region, allowing pollutants to accumulate. However, pollutant carryover from the previous days will be low, resulting in high-Good AQI levels. Thursday, moderate and gusty southeasterly winds will shift to westerly in the afternoon as a surface low pressure system moves across Ohio, increasing dispersion. In addition, rain showers, cloud cover, and cool temperatures will hinder ozone formation. These conditions will lower AQI levels to Good. Friday and Saturday, northerly winds behind the departing low pressure system will transport clean air into central Ohio, allowing AQI levels to remain Good on both days. Sunday, as surface high pressure moves across Ohio, calm morning winds will become light southerly in the afternoon, reducing mixing and dispersion. In addition, increasing sunshine will enhance ozone production in the Columbus region. These conditions will lead to high-Good AQI levels.
