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, February 17: Light winds early in the day will inhibit pollutant dispersion, allowing pollutants to accumulate in the Columbus region. However, breezy southeasterly afternoon winds will increase mixing in the low levels of the atmosphere, aiding pollutant dispersion. As a result, AQI levels will be low-Moderate. Tuesday, February 18: A cold front will move through Ohio, increasing vertical mixing in the atmosphere and generating breezy winds at the surface. These conditions will effectively disperse pollutants, lowering AQI levels to Good. Wednesday and Thursday, northwesterly winds behind the departing cold front will transport a clean, cool air mass into central Ohio, keeping AQI levels Good on both days. Friday and Saturday, moderate southwesterly winds will disperse pollutants in the Columbus region, yielding continued Good AQI levels on both days.
