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: Tuesday, January 17th, 2017 through Monday, January 23rd, 2017 PM-2.5: 24-hour Fine Particulate concentrations are expected to be mostly Good to Low Moderates throughout the forecast period. FORECAST DISCUSSION: After experiencing an active weather week, things should calm down and actually warm up a bit. A low pressure system is tracking through the region Monday morning bringing significant rainfall. As this system pulls away and high pressure builds in, westerly winds should provide Good Air Quality. The effects of the high pressure cell will last until Thursday when we see a shift to southerly winds and a warming trend that will last through the weekend. Southeasterly wind should prevail into Monday. Weekend temperatures will rise into the 40’s and, perhaps, even touch 50 degrees. With the melting snow and rainfall amounts, ample moisture will be available which tends to promote particulate growth. As a result, I believe the first half of this work week should be mostly Good with some Low Moderates in the more urban areas. When the winds shift to an easterly/southerly component on Thursday, I expect to see fine particulate counts to start creeping into the Low Moderate to Moderate range, which will likely persist through the weekend. EXTENDED FORECAST: Air Quality is expected to continue to be mostly Low Moderate to Moderate into the next work week.
