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: Monday, May 22: Increasing sunshine will enhance ozone formation in central Ohio. However, moderate westerly winds will bring clean air into the region, yielding Good AQI levels. Tuesday, May 23: Light easterly winds will limit pollutant dispersion, and partly to mostly sunny skies and warm temperatures will aid ozone formation. As a result, AQI levels will be low-Moderate. Wednesday and Thursday, as a low pressure system approaches from the southwest and impacts Ohio, mostly cloudy skies and rain showers will inhibit ozone formation. In addition, moderate southeasterly to southwesterly winds will increase pollutant dispersion. As a result, AQI levels will be Good on both days. 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, winds will weaken, limiting mixing and dispersion. However, low pollutant carryover from Friday will keep AQI levels Good.
