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: Tuesday, April 25: Light east-southeasterly winds will gradually bring moisture and pollutants into the Columbus region, enhancing particle production. In addition, partly to mostly sunny skies will aid ozone formation. However, low pollutant carryover from previous days will lead to high-Good AQI levels. Wednesday, April 26: Light to moderate south-southeasterly winds will transport additional pollutants into the Columbus area. Furthermore, mostly sunny skies and warmer temperatures will enhance ozone production. These conditions will lead to Moderate AQI levels. Thursday, as a cold front moves into Ohio, increasing clouds and rain showers will reduce ozone production. In addition, moderate southwesterly winds will disperse pollutants. Therefore, AQI levels will lower to Good. Friday, light and variable winds will reduce pollutant dispersion, and partly sunny skies will increase ozone formation. Therefore, AQI levels will be low-Moderate. Saturday and Sunday, mostly cloudy skies and scattered thunderstorms will inhibit ozone formation. However, southerly winds will transport regional pollutants into central Ohio, keeping AQI levels low-Moderate on both days.
