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: At 2 p.m. EST this Friday afternoon, low pressure located over Quebec, Canada, continues to send a west to northwesterly flow of chilly air into the region. Cold air aloft will keep things on the cloudy side through Saturday, and a weak area of low pressure can bring a rain or snow shower later Sunday into Sunday night. Rather cloudy and brisk tonight with low temperatures close to 30 degrees. *** Saturday's forecast: Colder air aloft will keep things on the cloudy side for the day Saturday, and there will still be enough mixing to where fine particulate remains in the good range. *** Sunday's forecast: A weak low pressure area coming across the area will bring a rain or snow shower later Sunday into Sunday night, with temperatures no better than the lower 40s. Lighter winds and less vertical mixing will result in fine particulate levels becoming moderate. *** Monday's forecast: Clouds and a little sunshine for the day Monday with a seasonably chilly afternoon as temperatures move into the lower to middle 40s. Lesser low level mixing and an inversion possibility may keep PM2.5 at moderate levels, with the highest concentrations Monday morning. *** Extended forecast: Things will temporarily turn milder by Tuesday with a southerly flow out ahead of a storm system coming out of the Mississippi valley. Periods of rain are possible with this system, and temperatures will also climb into the lower 50s. With rainfall washout and stronger mixing, fine particulate will fall back to the good range. Colder air, perhaps the coldest air mass of the season, will follow behind the storm later next week with good air quality.---McAuliffe
