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: Monday, April 6: Cold morning temperatures will generate a strong inversion, trapping pollutants near the ground. However, light southeasterly winds will aid mixing, and daytime heating will enhance mixing in the atmosphere. As a result, AQI levels will be Good. Tuesday, April 7: Light to moderate southwesterly winds early in the day will gradually transport pollutants into the region. In addition, increasing moisture associated with a passing warm front will enhance particle formation. These conditions will yield high-Good AQI levels. Wednesday and Thursday, as a cold front moves across the Buckeye State, moderate and gusty westerly to west-northwesterly winds will aid mixing and effectively disperse pollutants. These conditions will lead to Good AQI levels on both days. Friday and Saturday, surface high pressure over the eastern U.S. will generate light to moderate westerly winds. These winds will transport clean air into the state, keeping AQI levels Good on both days.
