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, May 14th, 2018 through Monday, May 21st, 2018 Ozone: 8-hour Ozone concentrations will be generally Good with some Moderates possible near Southeast Michigan during the mid-week period. PM-2.5: 24-hour Fine Particulate concentrations will be mostly Good with some Low Moderates through the forecast period. FORECAST DISCUSSION The work week begins very wet with heavy rains in the southern portion of the state and the threat of localized flooding. The threat of rains and potential severe weather will persist into Tuesday before high pressure begins to build into the region. With the clouds and rain, any ozone threat will be non-existent but fine particulates could linger in the Low Moderate range. We will begin to dry out Tuesday afternoon as high pressure builds from the west. Winds will have an easterly component and I expect both ozone and fine particulates will stay mostly in the Good range. I expect this pattern to persist through Friday with daytime temperatures in the 70’s and dewpoints comfortably in the low 50’s. With the easterly wind regime, ozone formation is unlikely, especially along the Lake Michigan shoreline. However, some areas immediately downwind of Detroit may see a creep into the Moderate range during the mid-week time frame. The next best shot for any rain will occur during the weekend as a cold front approaches from the northwest. Saturday may be the best chance for any widespread Moderate conditions as winds briefly shift to the southwest in advance of the front. Once the front passes late Saturday and early Sunday, northwest winds will clear out any leftover Moderate readings and provide Good Air Quality for the rest of the weekend I do not expect any serious threat to the ozone threshold beyond Moderate with the mid-week sunny skies and warmer temperatures. However, if conditions change, I will update the forecast accordingly. EXTENDED FORECAST: Air Quality is expected to be mostly Good going into the next work week.
