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: As of 2 p.m. EDT this Friday afternoon, skies were clearing across the region with seasonable temperatures. Most locations are in the good range with respect to fine particulate, but there are a few who remain at moderate levels this afternoon. Tonight, clouds will linger across the area with fine particulate falling into the good range. *** Saturday's forecast: Low pressure tracking across the Tennessee valley on Saturday will bring a little rain to southwestern Pennsylvania from the late morning hours into the evening. A north to northeasterly flow will keep fine particulate levels down inside the good range. Cool with highs in the middle 50s. Partly to mostly cloudy Saturday night with temperatures falling back to near 40 degrees. *** Sunday's forecast: High pressure nosing southward will bring some breaks of the sun for the day Sunday, with a seasonably cool afternoon. East to northeasterly winds along with drier air will mean low concentrations of particulate matter. Partly cloudy Sunday night with lows in the lower 40s. *** Monday's forecast: Clouds and some sunshine for the day on Monday with temperatures climbing into the middle and upper 60s. Fine particulate matter will be on the increase, but good air quality will still prevail. *** Extended forecast: Clouds and a little sun for Tuesday. Low pressure off the east coast will be too far away to bring our area any rainfall. A weak cold front may arrive late Wednesday or Wednesday evening with a shower or two. High pressure then regains control of the weather for the latter part of next week, and with warmer air possible, both fine particulate and ozone levels may rise again.---McAuliffe
