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: A soggy first half to the weekend is on tap, beginning Friday. Increasing warmth and moisture, particularly above the surface layer will lead to some fog, mist, or drizzle starting Friday morning, which may persist through the day. A strongly capped surface layer will result, trapping particle pollution near the surface. While precipitation processes will generally help scour this pollution through the day, air quality will persist near the Good/Moderate threshold for much of Friday. Continued wet conditions are expected for much of Saturday as an upper level trough moves through the region. While saturated low-levels of the atmosphere will cap the surface layer once again, the lengthy period of precipitation will have scoured much of the fine particle pollution, improving the air quality load to the Good AQI range. On Sunday northwest winds will bring drier conditions and Good air quality. –MDE
