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)

Forecast Discussion: Current conditions: Brisk and cold conditions this Friday afternoon with a couple of snow showers lingering across the area. Strong surface mixing has acted to keep PM2.5 concentrations down inside the good range. *** Saturday's forecast: A cold wind will persist Saturday along with mostly cloudy skies and a snow shower or two. The gusty wind will result in fine particulate levels not changing much over Friday. *** Sunday's forecast: The month of March will see temperatures march upward as the mercury maxes out in the upper 40s under a mostly sunny sky. A shift in winds to the southwest means a rise in fine particulate to the upper good range. *** Monday's forecast: Clouds will make a comeback on Monday with a bit of rain possible as a weak area of low pressure affects us. Limited mixing may again cause particle concentrations to go moderate. *** Extended forecast: The weather across the region will be unsettled, but on the mild side Tuesday into Wednesday as waves of low pressure riding along a stalled out cold front to our south and east. It will turn chillier later on in the week as winds shift back into the west and northwest. Air quality will average in the moderate range Tuesday, but increasing winds and precipitation bring values down into the good zone Wednesday into Thursday.---McAuliffe
