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, December 18: Southerly to southwesterly winds will gradually transport regional pollutants and moisture into the Columbus area, enhancing particle formation. However, these winds will also keep the lower levels of the atmosphere well mixed, leading to high-Good AQI levels. Tuesday, December 19: Southwesterly winds will strengthen as a cold front moves through central Ohio in the afternoon, dispersing pollutants and keeping AQI levels Good. Wednesday, light northerly winds behind the departing front will transport a clean air mass into the Columbus region, keeping AQI levels Good. Thursday and Friday, light to moderate southeasterly to southerly winds will gradually transport pollutants and moisture into central Ohio, increasing particle production. However, low pollutant carryover from day to day will lead to high-Good AQI levels on both days. Saturday, as a low pressure system moves through the Buckeye State, moderate and gusty westerly winds will disperse pollutants and bring clean air into the Columbus region, yielding Good AQI levels.
