AQI: Good (0 - 50) AQI: Good (0 - 50)
Air quality is considered satisfactory, and air pollution poses little or no risk.
AQI: Moderate (51 - 100) AQI: Moderate (51 - 100)
Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
AQI: Unhealthy for Sensitive Groups (101 - 150) AQI: Unhealthy for Sensitive Groups (101 - 150)
Although general public is not likely to be affected at this AQI range, people with lung disease, older adults and children are at a greater risk from exposure to ozone, whereas persons with heart and lung disease, older adults and children are at greater risk from the presence of particles in the air.
AQI: Unhealthy (151 - 200) AQI: Unhealthy (151 - 200)
Everyone may begin to experience health effects members of sensitive groups may experience more serious health effects.
 AQI:Very Unhealthy (201 - 300) AQI: Very Unhealthy (201 - 300)
Health alert: everyone may experience more serious health effects.
AQI: Hazardous(301 - 500) AQI: Hazardous (301 - 500)

Forecast Discussion: Tuesday, August 22: Southwesterly winds will strengthen ahead of an approaching cold front, aiding pollutant dispersion in central Ohio. In addition, increasing cloud cover and scattered thunderstorms will limit ozone formation. These conditions will lead to Good AQI levels. Wednesday, August 23: Light to moderate northwesterly winds behind the departing front will disperse pollutants and gradually bring clean, cool air into the region. As a result, AQI levels will remain Good. Thursday through Sunday, an upper-level trough of low pressure will approach and pass through the Columbus area, enhancing mixing in the atmosphere. Furthermore, cooler temperatures will limit ozone production, and light to moderate northerly to northeasterly winds will aid pollutant dispersion. Therefore, AQI levels will be Good on all four days.
