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: FORECAST SUMMARY: Monday, August 19th, 2019 through Monday, August 26th, 2019 Ozone: 8-Hour average Ozone concentrations will be mostly Good to Moderate during Monday and Tuesday, then mostly Good through the remainder of the forecast. PM-2.5: 24-hour average Fine Particulate concentrations will be mostly Good. FORECAST DISCUSSION Monday and Tuesday will be seasonal with temperatures in the mid-to-upper 80’s with increasing humidity. High pressure builds in during Monday and should persist through Tuesday. Any chance for some creep in ozone concentrations, during this forecast period, should occur during these two days as light winds become more southwesterly during Tuesday. Although I expect ozone to begin inching up, there is no compelling evidence that we will get into the USG range during Tuesday although I do expect concentrations to get up in the High Moderate range. If it were early July, I would probably be more concerned, but the shorter days of late summer should work in our favor. A cold front is projected to pass through the region Tuesday night into Wednesday. The cooler, dryer air mass that follows the front should keep us solidly in the Good category through the remainder of the work week. I do see a bit of a warmer during the weekend as winds shift around to the southeast, but nothing is indicating a buildup of ozone to anything worse than Low Moderate. EXTENDED FORECAST: Air Quality should be mostly Good to Low Moderate going into the next work week.
