Forecast Discussion: A warming trend will begin on Saturday and continue through Monday. Southwesterly winds will bring warmer and moister air into the Philadelphia metropolitan area. Warm air arriving aloft will create daily morning surface inversions, which will trap pollutants. As a result, particle concentrations will persist in the Moderate range over the weekend. A cold front will move through Philadelphia around noon on Monday. The passage of the front will be late enough in the day that daily average particle concentrations on Monday will remain in the Moderate range. **Extended Forecast: Colder and drier air will filter into the Mid-Atlantic region on Tuesday. Sustained northwesterly winds, both aloft and at the surface, will return air quality to the Good range. -Huff
