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: *** Saturday’s Forecast: Unsettled weather will return to the region on Saturday with showers and thunderstorms expected over the later portion of the day. Increasing cloud cover will limit afternoon highs to the upper 80s to near 90 degrees as well as limit ozone concentrations to levels in the high end of the good range. PM-2.5 concentrations should stay in the lower end of the moderate range with light winds limiting mixing. Some of the thunderstorms may produce heavy rainfall that will at least temporarily improve air quality conditions heading into the early morning hours on Sunday. *** Sunday’s Forecast: Cloud cover once again on Sunday will limit ozone formation to keep levels in the high end of the good range. Similar to Saturday, highs are expected to again reach the upper 80s to near 90 degrees. Unsettled weather will continue with another round of showers and thunderstorms possible. These may be more scattered in development than the rainfall from Saturday. Some locations will see PM-2.5 concentrations dip into the high end of the good range, especially those that see at least moderate rainfall both Saturday and Sunday, while drier areas may climb just enough to reach the low moderate range for the day. *** Monday’s Forecast: The return of some sunshine is expected on Monday, pushing temperatures close to the 90 degree mark once again. However, an approaching cold front will bring a cooler and drier air mass to the region by late in the day. Even with the increase in sunshine, breezy flow out of the west will provide enough mixing to limit ozone formation. PM-2.5 concentrations may sit in the moderate range for at least the first half of the day before improving to the good range with the frontal passage. On average, concentrations will be in the low moderate range for the day. *** Extended Outlook: A much cooler and drier air mass moves in for Tuesday compared to what we have experienced over the prior week. Highs may struggle to reach the low 80s with dew point temperatures falling to much more comfortable levels in the low 60s. Good air quality is expected with ozone concentrations again in the high end of the good range. The break from the heat and humidity will be brief, as warmer and more humid air is quick to return for Wednesday/Thursday. Air quality conditions may return to moderate levels for both ozone and PM-2.5 as well. --- Roble
