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)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: Friday, December 9: An upper-level trough of low pressure over Ohio will enhance vertical mixing, and moderate westerly winds at the surface will keep pollutants well dispersed, yielding Good AQI levels. Saturday, December 10: As a surface high pressure system moves over Ohio, westerly winds will weaken, reducing pollutant dispersion. However, pollutant carryover from the previous days will be low. Therefore, AQI levels will remain Good. Sunday, light southerly winds ahead of an approaching low pressure system will limit pollutant dispersion in central Ohio, and morning fog and mist will enhance particle production. As a result, AQI levels will be low-Moderate. Monday and Tuesday, moderate westerly winds behind the departing low pressure system will transport clean air into the Buckeye State, resulting in Good AQI levels on both days. Wednesday, a cold front will move through the Columbus area, generating light northerly winds and continuing to transport clean air into the region. These conditions will keep AQI levels Good.
