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: Wednesday, August 16: Light and variable winds will reduce pollutant dispersion in the Columbus region, and mostly sunny skies and warm temperatures will enhance ozone production. These conditions, combined with pollutant carryover from Tuesday, will lead to high-Moderate AQI levels. Thursday, August 17: Strengthening southwesterly winds ahead of an approaching low pressure system will increase mixing in the atmosphere, dispersing pollutants. In addition, mostly cloudy skies and scattered thunderstorms will reduce ozone formation, lowering AQI levels to Good. Friday, moderate westerly winds behind the departing weather system will transport a cleaner air mass into the region, keeping AQI levels Good. Saturday, lighter winds will limit dispersion. However, mostly cloudy skies will inhibit ozone production, keeping AQI levels Good. Sunday and Monday, mostly sunny skies will enhance ozone formation, and light winds will continue to limit pollutant dispersion. Therefore, AQI levels will be Moderate on both days.
