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, October 17: Calm to light southerly winds will inhibit pollutant dispersion in central Ohio. However, pollutant carryover from previous days will be low. As a result, AQI levels will be Good. Wednesday, October 18: Surface high pressure over the southeastern U.S. will generate continued light southerly winds, limiting pollutant dispersion. Therefore, AQI levels will be low-Moderate. Thursday through Sunday, light southerly to southwesterly winds will reduce pollutant dispersion and gradually transport regional pollutants into the Columbus area. In addition, mostly sunny skies and warming temperatures will aid ozone formation. Therefore, AQI levels will be low-Moderate on all four days.
