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 Wednesday afternoon, a decent amount of mixing across the area has resulted in low PM2.5 concentrations across the region. Temperatures are running some 15 degrees lower than at this time Tuesday thanks to a passage of a cold front Tuesday night. High pressure building in from the Plains will bring a little bit of sunshine back to the area by later on Thursday. For tonight, we will have a partly to mostly cloudy sky with temperatures close to 32 degrees in the colder spots. *** Thursday's forecast: An area of high pressure will build into the area for the day Thursday. Mixing will be limited with light winds close to the surface, so fine particulate levels will go moderate in many locations. Not so cold with temperatures close to 50 degrees. *** Extended forecast: The long range period will bring an unseasonably mild flow of air from the south and southeast. Temperatures will average over 20 degrees above normal levels for the middle to latter part of January during this period. The pattern will also be an active one with a warm front bringing some rain Thursday night into Friday, and a strong area of low pressure coming out of the Plains resulting in very unsettled weather early next week. Fine particulate concentrations will be in the moderate range Friday into Sunday as winds remain light and pollutant dispersion will be limited. Stronger lower and upper level flow by the early part of next week will cause fine particulate concentrations to improve to the good range. Temperatures by the latter part of next week may start to retreat back towards normal as the main upper level flow shifts into a more northwesterly direction.---McAuliffe
