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: It will be a very pleasant weekend for the State of Delaware. Although temperatures will lag a bit below normal, high pressure will promote sunny skies and diminishing winds. A very dry air mass will remain in place over the Mid-Atlantic region through the weekend, which will inhibit particle formation. In addition, ample vertical mixing will help ventilate the atmosphere. Particle concentrations will rise slightly on Saturday and then again on Sunday, but daily average particle air quality will remain in the Good range. The center of high pressure will move offshore on Monday afternoon. Pleasant, seasonably cool and sunny weather will continue. Particle concentrations will increase in response to stagnation in the morning, but persistent dry air and a switch to onshore winds in the second half of the day will limit daily average particle air quality to the upper Good range. **Extended Forecast: A coastal storm will begin making its way up the Atlantic coast toward the Mid-Atlantic on Tuesday. Onshore winds will strengthen, both aloft and at the surface. Particles will drop back down lower in the Good range in response to the clean maritime flow. -Huff
