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: Winds will become just a bit stronger on Saturday as a new high pressure system moves into the southeastern U.S. However, low mixing heights throughout the day will keep fine particle concentrations a bit elevated. Expect generally Good air quality with a few isolated low Moderate areas possible where wood burning is prevalent. High pressure will slide off the Atlantic coast Sunday, into Monday. Weak southwesterly flow will cause an uptick in dew points. This along with a gradual deterioration of the air mass will lead to more widespread low Moderate conditions. By Tuesday, a cold front is expected to push through the area. Clean, Canadian air along with gusty winds will bring fine particle concentrations back into the Good AQI range. -MDE
