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: Thursday, September 29: An upper-level trough of low-pressure over Ohio will enhance vertical mixing in the atmosphere, and cool temperatures and mostly cloudy skies will inhibit ozone formation in the Columbus area. Therefore, AQI levels will be Good. Friday, September 30: The upper-level trough will remain over the Great Lakes region, enhancing vertical mixing. Furthermore, continued cool temperatures and overcast skies will inhibit ozone formation. These conditions will keep AQI levels Good. Saturday and Sunday, as a surface low-pressure system gradually moves north through Ohio, moderate southerly winds will keep the atmosphere well mixed in the Columbus region. In addition, mostly cloudy skies will continue to limit the formation of ozone. As a result, AQI levels will be Good on both days. Monday and Tuesday, increasing sunshine will aid ozone production, and lighter winds will reduce pollutant dispersion. While low pollutant carryover from previous days will keep AQI levels Good on Monday, AQI levels will increase to low-Moderate on Tuesday.
