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: The big story for the MLK holiday weekend is the major winter storm, which will impact the state Saturday afternoon through Sunday morning and bring a blast of Arctic air in its wake for later Sunday and Monday. A mix of precipitation types is likely for Delaware, with some snow in New Castle County on Saturday afternoon before a change to all rain in the evening. Kent and Sussex Counties should experience all rain. Calm winds and a strong surface inversion on Saturday morning will keep hourly particle concentrations high for much of the day, until onshore (easterly) surface winds pick up in the afternoon and begin to decrease particles. The effect of the stronger winds will come too late in the day, however, which will keep daily average particles in the Moderate range on Saturday. Rain will be heavy at times overnight into Sunday morning, which will help to clean out the atmosphere. Extremely cold and dry air will surge into the state Sunday afternoon on gusty northwesterly winds, returning particles to the Good range. MLK Day will be extremely cold and blustery, with persistent Good air quality. High pressure will move overhead on Tuesday, diminishing winds. Particle concentrations will rise but remain in the Good range due to the clean and very dry air mass. **Extended Forecast: Another storm will approach the state on Wednesday. Temperatures will finally rebound, as southerly winds bring warmer and more humid air back into the region. Limited vertical mixing and rising atmospheric moisture will push particles back into the Moderate range. -Huff
