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, June 24th, 2019 through Thursday, June 27th, 2019 Ozone: 8-Hour average Ozone concentrations will be mostly Good to Low Moderate through the forecast period. PM-2.5: 24-hour average Fine Particulate concentrations will also be mostly Good with some Low Moderate through the forecast period. FORECAST DISCUSSION A front moving through Michigan during Monday will provide clouds and scattered rain showers. Tuesday should begin a drying out period with the exception of some potential showers Tuesday night. Temperatures will also start a warming trend with climbing into the upper 70’s with a rising dew point into the 60’s. Wednesday will be warm and dry with a westerly wind pattern and mostly clear skies. We could see some creep in ozone values into the Low Moderate range along the southern Lake Michigan shoreline and Southeast Michigan. Thursday could continue the ozone creep, although it should not get into the USG range. Temperatures will climb into the lower 80’s with scattered cloud cover and light winds. I will keep an eye on Thursday to make sure it doesn’t get any worse. The upcoming weekend looks to be the first real “summer-like” weekend of the season. Temperatures will climb into the mid-80’s with a juicy dew point in the upper 60’s. Winds will be light and skies partly cloudy. The wind direction is not ideal for ozone formation, but the low wind speed could allow for some stagnation. As this time year is optimal for ozone potential, it will certainly need watching. As such, the regional forecasters will have another call on Thursday to finalize a weekend forecast. EXTENDED FORECAST: Air Quality is expected to remain mostly Good to Moderate going into the weekend.
