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)

Forecast Discussion: Current conditions: East to southeasterly winds are increasing across the area this Friday afternoon, and so PM2.5 values which were more elevated this morning are beginning to decrease. Tonight, rain will arrive as an area of low pressure comes eastward out of the Ohio valley, and this rain will act to clean things out even more. *** Saturday's forecast: Rain will fall, heavy at times Saturday morning before tapering to showers by afternoon. The early morning rain intensity will keep fine particulate down in the good range for once. Turning out partly cloudy but not too cold Saturday night. *** Sunday's forecast: Turning out partly sunny and breezy for the day Sunday, with temperatures remaining well above normal. Good low level mixing should maintain good air quality. *** Monday's forecast: Brisk northwesterly winds on Monday with clouds and a little sunshine. Plenty of horizontal mixing will again allow for particle concentrations to remain low. *** Extended forecast: The next cold front may affect us during the mid week period, then a northerly flow behind it may send temperatures back down close to normal later on in the week. Overall air quality should remain good.---McAuliffe
