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: Weak winds and very warm temperatures are expected over the next several days as strong high pressure persists off the Atlantic coast. Ozone production will be favorable over this time frame. However given the intense heat and humidity, scattered late afternoon thunderstorms will be likely helping to mix in some cleaner air from aloft. Generally Moderate conditions are forecast Monday, Tuesday and Wednesday with high Moderate anticipated along the I-95 corridor. USG conditions are certainly possible during this period if the late afternoon thunderstorms do not materialize. Conditions will be monitored closely over the next several days. –MDE
