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, partly cloudy skies prevail over the region as a weak frontal system remains just off to our north. At the same time, a decaying mesoscale complex system (MCS) is migrating just south of our area into West Virginia. This system coupled with the frontal system near our area is helping to drive the clouds in today. In addition, the winds remain light out of the northwest. The cloud cover has helped to limit temperatures to the mid 80s today while the northwesterly flow has controlled ozone to near the good / moderate threshold. Expect air quality levels to continue to be near the good / moderate threshold for the duration of the weekend as more precipitation moves in. Now onto the day-to-day details... *** On Saturday, expect the skies to turn mostly cloudy as another cluster of storms (similar to those that passed to the south of our area on Friday) to move along the stalled boundary over PA. Unlike Friday, the center of the storm looks to pass right through western PA. This storm will not only limit ozone formation during the day but will also help to hold PM 2.5 near the good / moderate threshold, regardless of temperatures reaching into the mid 80s again. *** For Sunday, mostly cloudy skies will continue to be the rule as we continue to contend with a frontal system moving in from the west. The main front will likely press into the region late in the day. However, precipitation will likely develop in advance of the front, producing rain as it moves through our area. Southerly winds will persist across the region until the front pushes through so expect afternoon highs to still peak in the 80s. It will be the cloud cover and rain chances that limits ozone formation to the good range. Expect PM 2.5 levels to be much closer to the good / moderate threshold thanks to humidity levels remaining elevated. *** On Monday, mostly cloudy skies in the morning will give way to peaks of sunshine in the afternoon as the frontal system, which produced rain over our area on Sunday, moves off to our east. After the front moves through, the winds across the region will turn out of the northwest. The northwesterly flow will, in turn, allow slightly cooler air into the region. More importantly, we will begin to see an improvement in the humidity levels as lower dewpoint temperatures move into the area. Overall, expect air quality levels to be within the good range. *** Extended Outlook: As we take a peek into next week, we notice that we begin to see some relief in the warmth and humidity build into the region. This relief will come compliments of a cold front passage early in the week. Once the front moves through late Sunday / early Monday, winds will turn out of the northwest and will help to deliver the cooler / drier air to our area. Conditions will stay rather pleasant through the week. During the second half of the week, we will see temperatures to begin to rebound. However, that will be short-lived as a new frontal system is slated to push through by Friday. The front will then deliver another cool / dry air mass to start the new weekend. Overall, air quality levels are expected to remain near the good / moderate threshold as the progressive weather pattern continues through the week. --Nolan
