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: At 2 p.m. EDT this Friday afternoon, low pressure located across the Midwest has a stationary front extending eastward from it to the Mid-Atlantic coast. Showers and thunderstorms are developing across western Pennsylvania as a result, and this activity will continue on and off into Saturday in the vicinity of this front as it comes back northward as a warm front. *** Saturday's forecast: Mostly cloudy and humid Saturday with showers and thunderstorms developing as a warm front attempts to move through the area. With all of the cloud cover and rainfall potential, ozone and fine particulate will remain in the good range. *** Sunday's forecast: Clouds and a little sunshine for the day Sunday, but a cold front coming southward may trigger a thunderstorm or two across the area, mainly during the afternoon and evening hours. Ozone may go into the lower moderate range if there is enough sunshine, and the air will be humid enough to support moderate levels of PM as well. *** Monday's forecast: An influx of drier and less humid air from the north on Monday will send fine particulate and ozone down to the good range once more. High temperatures Monday will recover close to the 80 degree mark. *** Extended forecast: High pressure will hang on into Tuesday, bringing plenty of sunshine and warm air during the afternoon, which will act to produce moderate concentrations of ozone. Light winds and a morning inversion may also bring fine particulate to the moderate range as well. Both ozone and fine particulate might go a little higher moderate if smoke resulting from Canadian wildfires can be transported far enough south. The next weather system then brings back rainfall Tuesday night into Wednesday.---McAuliffe
