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 25: Cloudy skies and scattered showers will reduce ozone production in the Columbus region, and moderate northwesterly winds will keep the low levels of the atmosphere well mixed. These conditions will lead to Good AQI levels. Thursday, April 26: Mostly sunny skies will aid ozone formation in central Ohio, and light winds will limit pollutant dispersion. Therefore, despite low pollutant carryover from Wednesday, AQI levels will be low-Moderate. Friday, as a low pressure system passes to the north of the Columbus area, light westerly winds will aid pollutant dispersion. However, partly to mostly sunny skies will support ozone formation. Therefore, AQI levels will be low-Moderate. Saturday, moderate northwesterly winds behind the departing low pressure system will increase pollutant dispersion, leading to Good AQI levels. Sunday, northwesterly winds will weaken, reducing mixing and dispersion. Furthermore, mostly sunny skies will enhance ozone production. These conditions will lead to low-Moderate AQI levels. Monday, southerly winds will bring additional pollutants into central Ohio, and mostly sunny skies will continue to support ozone formation, leading to Moderate AQI levels.
