Pennsylvania – A sharp, biting chill settles over the region this morning, with clear skies masking how quickly conditions can turn. By Saturday, clouds thicken and light snow may start to mix in, leaving damp pavement vulnerable to flash freezing after sunset.
According to the National Weather Service in Mount Holly, snow is possible late tonight into Saturday, with a rain-and-snow mix developing by late morning. Highs climb into the low 40s Saturday, but temperatures fall fast once precipitation tapers, limiting accumulation while increasing slick spots.
Across eastern Pennsylvania, the weekend brings a familiar January pattern. Brief snow showers, gusty breezes, and falling temperatures combine to raise travel concerns. In Philadelphia, bridges, ramps, and untreated side streets may glaze quickly Saturday evening. Drivers should slow down and expect changing conditions.
Saturday night turns mostly cloudy with lingering moisture. Sunday stays cold with a 30 percent chance of snow and highs near 35. Even light snow can reduce visibility and traction, especially along I-95 and surface streets near the Schuylkill and Delaware rivers.
MLK Day offers sunshine but little warmth. Highs reach the mid-30s, while Monday night plunges into the lower teens under clear skies. Wind chills will feel even colder, making it one of the harshest stretches so far this winter. Tuesday remains sunny but cold, with highs near 23.
Meteorologists are now tracking a broader winter pattern next week. Colder air remains locked in across the East as precipitation chances rise across the Mid-Atlantic by midweek. Conditions may shift quickly as winter continues its steady takeover.
