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)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: Wednesday, June 26: Light to moderate southwesterly winds will transport regional pollutants into central Ohio, and warm temperatures and mostly sunny skies will enhance ozone production. Therefore, despite scattered afternoon thunderstorms aiding pollutant dispersion, AQI levels will be low-Moderate. Thursday, June 27: Light west-southwesterly winds will reduce pollutant dispersion and gradually bring additional pollutants into the Columbus region. Furthermore, partly to mostly sunny skies and temperatures near 90F will support ozone formation. As a result, AQI levels will be Moderate. Friday and Saturday, generally light west-southwesterly winds will reduce dispersion and gradually bring additional pollutants into the Columbus region. In addition, partly to mostly sunny skies and temperatures near 90F will support ozone formation. These conditions will keep AQI levels Moderate on both days. Sunday, as a weak front moves south through central Ohio, clouds and rain showers will reduce ozone formation, and northwesterly winds will bring cleaner air into the region. Therefore, AQI levels will lower to Good. Monday, light winds will reduce pollutant dispersion, and sunny, warm conditions will enhance ozone formation. As a result, AQI levels will be low-Moderate.
