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, February 27th, 2017 through Friday, March 3rd, 2017 PM-2.5: 24-hour Fine Particulate concentrations through Friday will range between Good and low Moderate. FORECAST DISCUSSION: Monday will be quite with comfortable temperatures for the end of February. Southerly winds could cause some southern monitors to hit low Moderate for fine particulate; otherwise, readings will remain Good. A low pressure area will bring precipitation to the state starting early Tuesday, lasting through Wednesday. Southwesterly winds and increased moisture on Tuesday could allow for Moderate fine particulate across central and southern parts of the state. As the system pulls away Wednesday, winds change to the northwest and clean/cooler air moves in. Any Moderate fine particulate from Tuesday will improve to the Good range Wednesday. High pressure moves in briefly Thursday before a clipper slides in from the northwest bringing with it some snow late Thursday/early Friday. Weaker winds Thursday turn northwest Friday after the clipper passes. Even with the weaker winds for part of Thursday, fine particulate during this period is not expected to increase much. Fine particulate will remain Good Thursday and Friday. EXTENDED FORECAST: High pressure slides overhead, then east of the state Saturday, and models show a warm front lifting north through the state early Sunday. Southerly winds be in place until a cold front passes sometime Monday. I do not expect a significant increase in fine particulate during this period; however, I will update this forecast Friday do determine whether or not Moderate forecasts for fine particulate will be needed.
