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: Low pressure passing to the south will promote unsettled conditions in the State of Delaware throughout the day on Wednesday. Showers will linger across the state in the morning and afternoon before scattered thunderstorms develop in the late afternoon and evening hours. Periods of sun and clouds will allow temperatures to reach the mid-80s °F. Increasing cloud cover, periods of precipitation, a relatively clean air mass in place will return ozone and particles to the Good range. **Extended Forecast: Periods of heavy rain overnight and into Thursday morning will give way to a pleasant day across the state. High pressure to the north will clear clouds by lunchtime, allowing temperatures to reach the low-to-mid-80s °F. Localized transport aloft and a strong sea breeze will allow ozone to rise back into the Moderate range. Particles will be slow to respond to stagnant conditions and will remain in the upper Good range. Pleasant conditions will continue for the end of the work week on Friday with seasonable temperatures and mostly sunny skies. High pressure centered to the northeast and a low pressure system moving into the Ohio River Valley will promote clean onshore flow, for Good air quality. -Enlow/Huff
