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.

Forecast Discussion: Current conditions: At 2 p.m. EST this Friday afternoon, much colder air has been driven into the area on a brisk northwesterly flow. Temperatures are running some 30 degrees colder than Thursday's readings. Mixing has been adequate enough to keep fine particulate levels down in the good range. Mostly cloudy for tonight with sleet, snow, and a bit of freezing rain as a nearly stationary front to the south creeps northward. *** Saturday's forecast: Snow and sleet will eventually turn to plain rain as temperatures rise to the middle 30s. Light winds and limited mixing will send fine particulate into the moderate range. *** Sunday's forecast: High pressure will build back into the area for Sunday as a slow moving frontal boundary pushes further to the south. Seasonably cold with high temperatures pushing 40 degrees. Ample mixing should mean particle levels will drop into the good range. *** Monday's forecast: Overcast and turning milder on Monday with any sleet or ice in the morning turning to a bit of rain by afternoon. High humidity and less mixing will send fine particulate into the moderate range. *** Tuesday's forecast: A mild southerly flow will bring showers to the area on Tuesday and the mercury may go well into the 50s. Stronger mixing from the south will bring particulate matter down into the good range. *** Extended forecast: Most of the middle to latter part of the week will bring mild conditions with temperatures averaging well above normal. Dry weather should prevail Wednesday into Thursday with rain possible by Friday. Good air quality will prevail most of this period.---McAuliffe
