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: Current conditions: Low pressure is tracking across the lower Great Lakes this Tuesday afternoon, with a trailing cold front southwestward into the eastern Ohio valley. At this time, thunderstorms are firing up across central and northern Ohio along the cold front, and some of these storms will affect the area over the remainder of this afternoon into the evening. *** Wednesday's forecast: Breezy with periods of clouds and sunshine Wednesday as high pressure builds eastward into the area from the Ohio valley. A northwesterly breeze will transport clean and drier air into the area, resulting in good air quality with respect to both ozone and fine particulate. *** Extended forecast: High pressure sinking to the south will shift winds into the southwest later this week, resulting in mostly sunny skies and eventually increasing humidity. Ozone concentrations will ramp up with the sun and warm air, so moderate readings are possible as early as Thursday, with the highest ozone levels most likely Friday as temperatures max out in the middle 80s. The chances for afternoon convection will increase as we move into the Memorial Day weekend as we are increasingly squeezed between a tropical system coming up from the south and low pressure coming across the Great Lakes. Therefore, ozone levels should lower some Sunday into Memorial Day.---McAuliffe
