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: Sunday, August 18 and Monday, August 19: Light to moderate southwesterly winds will bring pollutants into the Columbus region, and partly to mostly sunny skies and temperatures in the low-90s will enhance ozone formation. Therefore, despite isolated thunderstorms limiting ozone production each day, AQI levels will be Moderate on both days. Tuesday and Wednesday, as a cold front approaches central Ohio, increasing clouds will reduce ozone production, and scattered thunderstorms each day will increase vertical mixing in the atmosphere. However, warm temperatures will continue to aid ozone formation, yielding low-Moderate AQI levels on Tuesday and high-Good AQI levels on Wednesday. Thursday and Friday, light to moderate northerly to northeasterly winds behind the departing front will disperse pollutants and transport cleaner air into central Ohio. However, gradually clearing skies will increase ozone production, leading to high-Good AQI levels on Thursday and low-Moderate AQI levels on Friday.
