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.

Forecast Discussion: Tuesday will be hot and humid ahead of a cold front approaching from the west. High temperatures in the 90s °F and mostly sunny skies will promote ozone formation, but several factors should help to cap daily average ozone levels. Breezy winds in the afternoon will ventilate the atmosphere, and southerly transport aloft will bring clean maritime air into the state. In addition, there is a chance for scattered thunderstorms in the afternoon in the humid air mass. As a result, ozone should peak in the mid-to-upper Moderate range, mainly at locations in northern Delaware. Particles will linger in the upper Good range. **Extended Forecast: The strong cold front will move through the state early Wednesday morning. A delightfully less humid and seasonable air mass will build into the Mid-Atlantic region for the remainder of the week. Ozone and particles will drop into the Good range on Wednesday and Thursday. -Huff
