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, June 24: Light to moderate westerly winds behind a departing cold front will disperse pollutants and bring clean air into central Ohio. However, increasing sunshine and temperatures in the upper-70s will enhance ozone formation, leading to low-Moderate AQI levels. Sunday, June 25: Mostly sunny skies will support ozone formation in the Columbus area. However, moderate westerly winds will disperse pollutants. As a result, AQI levels will be Good. Monday, moderate westerly winds will persist, keeping the lower levels of the atmosphere well mixed. In addition, slightly cooler temperature will limit ozone production. As a result, AQI levels will be Good. Tuesday, light northwesterly winds will reduce pollutant dispersion, and mostly sunny skies and slightly warmer temperatures will aid ozone production. Therefore, AQI levels will be low-Moderate. Wednesday and Thursday, as surface high pressure passes over the region, southerly to southwesterly winds will bring pollutants into the area. Furthermore, sunny skies and increasing temperatures will enhance ozone formation. As a result, AQI levels will be Moderate on both days.
