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: Sunday, February 17: An approaching low pressure system will generate light to moderate east-northeasterly winds, transporting clean air into central Ohio. As a result, AQI levels will remain Good. Monday, February 18: Moderate west-northwesterly winds will disperse pollutants in the Columbus region, leading to continued Good AQI levels. Tuesday, winds will weaken as surface high pressure moves over the state, reducing pollutant dispersion and leading to high-Good AQI levels. Wednesday, easterly to southeasterly winds will strengthen as a low pressure system approaches from the southwest, dispersing pollutants and keeping AQI levels Good. Thursday, northwesterly winds behind the departing weather system will bring clean air into central Ohio, yielding Good AQI levels. Friday, light easterly winds will reduce mixing and dispersion, allowing pollutants to accumulate in central Ohio. Therefore, AQI levels will be high-Good.
