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: Thursday, August 22: Afternoon thunderstorms will enhance vertical mixing in the atmosphere, aiding pollutant dispersion. In addition, cloudy skies will limit ozone formation. Therefore, AQI levels will be Good. Friday, August 23 and Saturday, August 24: Increasing sunshine will aid ozone formation. However, moderate and gusty northeasterly winds each day will disperse pollutants, leading to Good AQI levels on both days. Sunday and Monday, partly sunny skies and temperatures in the low-80s will enhance ozone formation. However, moderate and gusty southeasterly winds will continue increasing pollutant dispersion. These conditions will allow AQI levels to be low-Moderate on both days. Tuesday, southerly winds will become west-southwesterly, which will transport regional pollutants into the Columbus area. However, low pollutant carryover, combined with scattered thunderstorms enhancing mixing, will lower AQI levels to high-Good.
