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, May 23: Light to moderate north-northeasterly winds will gradually bring clean air into the Columbus region. However, increasing sunshine will support ozone production, leading to low-Moderate AQI levels. Thursday, May 24: As an upper-level ridge of high pressure builds over Ohio, mostly sunny skies and warmer temperatures will enhance ozone formation in the Columbus region. Furthermore, light easterly winds will limit pollutant dispersion. As a result, AQI levels will be Moderate. Friday, the upper-level ridge will remain over Ohio, producing sunny skies and temperatures in the mid-80s. In addition, light southwesterly winds will bring pollutants into central Ohio. Therefore, AQI levels will be high-Moderate. Saturday and Sunday, increasing clouds and scattered thunderstorms will reduce ozone formation. However, light south-southwesterly winds will transport pollutants into central Ohio, and warm temperatures will aid ozone production. As a result, AQI levels will be low-Moderate on both days. Memorial Day, light winds will reduce mixing and dispersion. Therefore, despite overcast skies limiting ozone production, AQI levels will remain low-Moderate.
