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)
Health warnings of emergency conditions. The entire population is more likely to be affected.

Forecast Discussion: Wednesday, April 8: Light to moderate northwesterly winds though the morning hours will increase pollutant dispersion. However, these winds will also transport regional pollutants and smoke from numerous agricultural fires into the Columbus area. In addition, lighter afternoon winds will reduce dispersion. Therefore, AQI levels will be low-Moderate. Thursday, April 9, and Friday, April 10: As a cold front moves across the Buckeye State and departs to the east, moderate and gusty west-northwesterly winds will aid mixing and effectively disperse pollutants. These conditions will lead to Good AQI levels on both days. Saturday, as surface high pressure moves through southern Ohio, calm morning winds will reduce mixing and dispersion in the Columbus area, allowing pollutants to accumulate. In addition, an overnight temperature inversion will trap pollutants near the ground, and light southwesterly afternoon winds will bring additional pollutants into the region. Therefore, AQI levels will be high-Good. Sunday, southeasterly winds ahead of an approaching low pressure system will transport regional pollutants and moisture into central Ohio, enhancing particle production. However, winds will strengthen in the afternoon, dispersing pollutants and keeping AQI levels high-Good. Monday, moderate westerly winds behind the departing low pressure system will transport clean air into central Ohio, yielding Good AQI levels.
