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: Current Conditions: As of 2 PM on Friday, overcast skies prevail across western PA as a cold front continues to advance in from the west. Right now, the cold front is over the Ohio Valley. Tropical moisture (associated with the remnants of Tropical Storm Cindy) are riding northward in advance of the front. This moisture is producing heavier rainfall amounts across portions of the Ohio Valley / Tennessee Valley regions and is heading our way. Overall, with temperatures in the 70s and with thick cloud cover overhead, ozone has had a hard time rising out of the low good category. Expect the air quality levels to continue in the good range this weekend as cooler and drier air filters in. *** The Weekend Forecast: On Saturday, mostly cloudy skies in the morning will give way to partly sunny skies by the afternoon as the cold front, which produced heavy rain over our area on Friday, moves off to our east. At the same time, a new high pressure system will begin to take shape over the Plains. The combination of the departing front and incoming high will keep our winds out of the west. The additional sunshine during the afternoon will help to drive afternoon temperatures well into the 70s. Even though the peaks of sunshine will help warm temperatures, it will not be enough to help ozone rise out of the good range. On Sunday, we should see even more sun as the high pressure system off to our west shifts over the central Plains. The positioning of this high will keep our winds out of the west, allowing us to tap into a cooler and drier air mass. As a result, expect afternoon temperatures to drop 5 to 10 degrees from Saturday's highs. The air mass will also be relatively clean in nature resulting in good ozone concentrations across the region. By Monday, we should see peaks of sun in the morning give way to cloudiness in the afternoon as our high pressure system slowly progresses east. At the same time, a weak disturbance will move in over the Great Lakes, which could help produce some light rain showers late in the day over our area. Overall, it will be the additional afternoon cloud cover and continued cool / dry conditions that will limit ozone formation to the good threshold. --Nolan
