Forecast Discussion: An Arctic air mass will filter into the Philadelphia metropolitan area on Friday. It will be cloudy for most of the day, with gradual clearing by the late afternoon. Although the new air mass will be clean, stagnating winds overnight and a persistent snowpack will limit atmospheric mixing, which will allow particles to remain in the Moderate range. **Extended Forecast: Saturday will be the nicer of the weekend days, although still cold. It will be sunny with light winds as surface high pressure slowly moves overhead. Moderate air quality will continue. As high pressure moves offshore on Sunday, surface winds will be light and recirculating. Temperatures will rebound to above freezing in southerly flow ahead of an approaching cold front. Cloud cover will steadily increase during the day, with a chance for wintery precipitation to overspread the area beginning in the late afternoon. Particle concentrations may approach the upper end of the Moderate range in the modified and stagnant air mass. -Huff
