Pennsylvania – Thick flakes sweep across porch lights this Sunday morning, coating cars, lawns, and city streets in a fast-growing layer of slushy snow. Pavement glistens as packed sections freeze, creating early-season slick spots that catch drivers off guard during the busy week-before-Christmas rush.
According to the National Weather Service, a Winter Storm Warning remains in effect until 1 p.m., with 4 to 6 inches expected across portions of southern New Jersey and southeast Pennsylvania, including Philadelphia. Snow continues at a steady clip through late morning before tapering into lighter, blowing bands. Travel may slow most on I-95, Route 1, and bridges leading into South Jersey, where visibility dips fast during heavier bursts.
Meteorologists say a very cold arctic air mass follows this storm, dropping temperatures sharply by early Monday. Wet pavement could flash-freeze during the afternoon as winds increase from the northwest. For drivers, that means slippery bridge decks, black ice on neighborhood streets, and sudden loss of traction at intersections. Keep extra space between cars and clear snow from headlights before heading out.
The bigger question now is Tuesday. Latest model runs hint at a “winter tease”—a weak disturbance that may brush the region with passing clouds and a stray flurry as colder air settles in. No new accumulation is expected for now, but the cold snap continues with highs near freezing and stubborn wind chills in the teens.
