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.

Forecast Discussion: Friday, December 2: Moderate westerly winds will disperse pollutants and transport a clean air mass into the Columbus region. As a result, AQI levels will be Good. Saturday, December 3: Westerly winds will persist in central Ohio, bringing a clean air mass into the region and keeping AQI levels Good. Sunday and Monday, as surface high pressure moves over central Ohio, light winds will limit mixing and dispersion, allowing pollutants to accumulate in the Columbus area. While low pollutant carryover from previous days will lead to Good AQI levels on Sunday, AQI levels will be low-Moderate on Monday. Tuesday, a low pressure system will move through Ohio, enhancing vertical mixing in the atmosphere and shifting winds to westerly at the surface. These conditions will disperse pollutants, lowering AQI levels to Good. Wednesday, moderate to strong westerly winds behind the departing system will keep pollutants well dispersed, yielding Good AQI levels.
