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: Thursday, December 12 and Friday, December 13: Light southeasterly winds will reduce pollutant dispersion in central Ohio. In addition, cold morning temperatures will produce a strong inversion, trapping pollutants near the ground. These conditions will lead to low-Moderate AQI levels on both days. Saturday, morning fog and mist will enhance particle production in the Columbus area. However, another cold front will approach the Buckeye State, shifting winds to northwesterly and aiding pollutant dispersion. Therefore, AQI levels will be high-Good. Sunday, moderate and gusty winds behind the departing cold front will transport cleaner air into central Ohio, resulting in Good AQI levels. Monday, winds will shift to southeasterly as surface high pressure passes over Ohio. These winds will continue to aid dispersion, allowing AQI levels to remain Good. Tuesday, a low pressure will move through central Ohio and shift winds to westerly. These winds will gradually bring cleaner air into the state, keeping AQI levels Good.
