Forecast Discussion: A warm front will pass through the Mid-Atlantic region on Saturday, promoting a rise in temperatures and dew points. The day will be partly to mostly sunny with breezy southwesterly surface winds in the afternoon. Early morning stagnation, warm air arriving aloft, and localized transport aloft will allow ozone and particles to reach the Moderate range. **Extended Forecast: An approaching cold front from the west on Sunday will trigger mostly cloudy skies and a chance for scattered showers across the Philadelphia metropolitan area. Ozone will fall into the Good range, and particles will rise slightly higher into the Moderate range due to continued humidity and westerly flow aloft. The rainy and cloudy weather will continue on Monday as the cold front reaches Philadelphia in the late morning or early afternoon. The arrival of a dry, clean, and cool air mass behind the front, along with sustained surface winds, will result in Good air quality. -Catena/Huff
