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, a mix of sun and clouds persist across the region as a frontal system remains draped across PA. Right now, light northerly flow along with the cloud cover is helping to limit temperatures to the low 80s. The cloud cover today is also limiting ozone formation to near the good / moderate threshold. Over the weekend, expect the threat of rain to increase as a wave of energy moves eastward along the front initially. Then a cold front passes through the region late in the period. Overall, the additional cloud cover and increased rain chances should limit ozone formation to the good range. Now onto the weekend's details... *** On Saturday, expect increasing cloudiness over the region as a new low pressure system moves eastward along the stalled boundary over PA. The center of this wave is expected to travel through PA (unlike Friday's wave, which passed just off to our south). This wave will increase the threat of rain across western PA. So even though temperatures will peak in the 80s, it will be the clouds and the rain that will force ozone into the good range. On Sunday, expect the clouds to hang over the region as a cold front pushes toward our region. In advance of the front, warm / moist air will continue to flow northward. Therefore, expect another round of showers to develop across western PA as the front pushes east. Temperatures will be seasonably warm with peaks in the 80s. Like Saturday, it will be the cloud cover and rain that will control ozone production to the good range. By Monday, the front that moved in on Sunday will push off to our east. As a result, expect the skies to begin to clear during the afternoon. Northwesterly flow will persist and allow cooler, drier air to build in. This new air mass will be relatively void of higher precursor concentrations needed for ozone formation so expect another GREEN ozone day. --Nolan
