The Northeast Extension of the Pennsylvania Turnpike, Interstate 476, is also reporting icing in the Lansdale area.
Temperatures in Philadelphia and areas to the south are still above freezing, forecasters say, and they are expected to remain that way, so roads are just wet.
Later today, the National Weather Service expects temperatures to rise toward the 50s with even a thunderstorm possible in the Philly area. By the weekend, the thermometer could reach the upper 50s.
