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: Tuesday, May 23: Moderate east-southeasterly winds will aid pollutant dispersion in the Columbus region. However, partly to mostly sunny skies and warm temperatures will enhance ozone formation. As a result, AQI levels will be low-Moderate. Wednesday, May 24: As a low pressure system approaches from the southwest, increasing clouds and rain showers will reduce ozone formation. In addition, light to moderate easterly winds will continue to disperse pollutants. These conditions will lead to Good AQI levels. Thursday, a low pressure system moving through Ohio will produce continued rain showers, limiting ozone formation. In addition, moderate southwesterly winds will keep pollutants well dispersed. Therefore, AQI levels will be Good. Friday, moderate west-northwesterly winds behind the departing weather system will transport a clean air mass into the Columbus region, keeping AQI levels Good. Saturday and Sunday, southerly to southwesterly winds will bring moisture and pollutants into central Ohio, increasing particle production. While low pollutant carryover from previous days will keep AQI levels Good on Saturday, AQI levels will be low-Moderate on Sunday.
