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: Thursday, March 30: Moderate and gusty southerly winds ahead of an approaching low pressure system will keep the lower levels of the atmosphere well mixed, yielding Good AQI levels. Friday, March 31: A low pressure system will move through the Columbus area, generating continued moderate southerly winds and scattered showers and thunderstorms. These conditions will enhance vertical mixing and result in continued Good AQI levels. Saturday, as the low pressure system departs Ohio to the east, moderate northerly winds will disperse pollutants and bring a clean air mass into the Columbus region. As a result, AQI levels will remain Good. Sunday and Monday, light northeasterly to easterly winds will continue to gradually bring clean air into central Ohio. Therefore, despite decreasing wind speeds inhibiting pollutant dispersion, AQI levels will be Good on both days. Tuesday, a low pressure system over the southeastern U.S. will generate light to moderate northerly winds. These winds will aid pollutant dispersion and yield continued Good AQI levels.
