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: Saturday, May 27: Light winds will limit pollutant dispersion in central Ohio. However, increasing clouds and isolated thunderstorms will reduce ozone formation, leading to Good AQI levels. Sunday, May 28: Southerly to southwesterly winds will bring moisture and pollutants into the Columbus region, increasing particle production. However, scattered showers and thunderstorms will aid vertical mixing and keep AQI levels Good. Memorial Day and Tuesday, moderate southwesterly winds will transport regional pollutants into central Ohio. Furthermore, mostly sunny skies and warm temperatures will aid ozone formation. Therefore, AQI levels will be Moderate on both days. Wednesday and Thursday, moderate west-northwesterly winds will disperse pollutants and bring cleaner air into the Columbus region. However, mostly sunny skies will continue to support ozone formation, yielding low-Moderate AQI levels on both days.
