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, January 16: As a cold front departs the Columbus region, light westerly winds will transport clean, cold air into the area, yielding Good AQI levels. Wednesday, January 17: Lighter westerly winds through the morning hours will reduce pollutant dispersion. However, winds will strengthen in the afternoon, dispersing pollutants and keeping AQI levels Good. Thursday and Friday, a surface high pressure system over the southeastern U.S. will generate moderate southwesterly winds in the Columbus area. These winds will aid pollutant dispersion, resulting in Good AQI levels on both days. Saturday and Sunday, light to moderate south-southwesterly winds will bring regional pollutants into central Ohio. However, low pollutant carryover from day to day will keep AQI levels Good on both days.
