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: High pressure centered over the Mid-Atlantic states is producing plenty of sunshine with nice weather this Thursday afternoon. While PM2.5 levels were on the high side this morning, brisk southwest winds have caused air quality to improve to the good range this afternoon. Over the next few days, PM2.5 levels will average well into the moderate range, with the highest concentrations likely during the late night and early morning hours. Concentrations are likely to average higher into the moderate range through Saturday due to less afternoon mixing and overall very light winds, and near stagnant morning air motion. Tonight will bring a mostly clear sky with fine particulate levels rising to the upper moderate levels late due to a developing inversion. *** Friday's forecast: Near calm winds will produce elevated levels of PM2.5 in the morning, then a little afternoon mixing will drop concentrations to the middle moderate range on average for the day. High temperatures close to 70 degrees. *** Extended forecast: Limited low level mixing will continue for the day Saturday with high pressure both at the surface and aloft. A light flow during the afternoon may be all that saves the area from average code ORANGE concentrations. Otherwise the day will be mostly sunny with afternoon temperatures in the lower to middle 70s. Even warmer conditions are likely for Sunday--a stronger amount of mixing means PM levels will drop to the lower moderate range. Increasing winds ahead of a strong cold front by Monday will drop PM levels further into the good range. Rain and thunderstorms associated with the front may affect us Monday night into early Tuesday, then a big cool down will occur behind the front Tuesday night into Wednesday with temperatures much closer to normal late October levels.---McAuliffe
