Philadelphia, Pennsylvania – A powerful arctic front moving through the Mid-Atlantic late Friday will bring dangerous cold, strong winds, and brief snow showers, with the coldest wind chills of the season expected Saturday night along major roadways including I-95, I-76, and I-295.
According to the National Weather Service Philadelphia/Mount Holly, high pressure will provide dry but chilly conditions through Friday before an arctic front sweeps across eastern Pennsylvania, New Jersey, Delaware, and northeast Maryland Friday night. The front may produce snow showers or brief snow squalls, though forecasters say snow accumulation is expected to remain minimal.
Behind the front, temperatures will drop sharply. Daytime highs Saturday and Sunday are forecast to remain in the teens and lower 20s, while northwest winds increase significantly. Forecast guidance shows wind gusts of 40 to 50 mph, especially near the coast, higher terrain, and exposed corridors such as I-95 near Philadelphia, the Atlantic City Expressway, and Route 1 in Delaware.
The combination of strong winds and bitter cold will drive wind chills well below zero Saturday night. The coldest values are expected across northern and interior areas, with wind chills ranging from -10° to -20°, and locally colder near the Poconos and Lehigh Valley. The National Weather Service warns these may be the lowest wind chills of the winter season.
Sunday will remain cold and windy before gradual moderation begins early next week. Forecasters note a warming trend is likely by midweek, with temperatures returning closer to seasonal averages.
Officials urge residents, commuters, and students to limit prolonged outdoor exposure, dress in layers, and prepare vehicles for extreme cold. Drivers should be alert for sudden reductions in visibility if snow squalls develop Friday night.
Additional updates or advisories may be issued as conditions evolve.
