Pennsylvania – Frost coats windshields and breath turns visible across the Delaware Valley this morning. Winter’s first full workweek starts cold and quiet, but change is already in motion. What looks calm now could turn slick as travel ramps up before Christmas Eve.
Early temperatures dipped into the upper 20s around Philadelphia, with wind chills in the low 20s. Sunshine dominates Monday, allowing highs to reach the low 40s. According to the National Weather Service, clouds thicken later today as moisture spreads east. Light snow may develop late tonight, especially across northern suburbs, though accumulations remain minimal.
By Tuesday, a warmer push arrives. Snow mixes with rain during the morning, then transitions mainly to rain by midday. Highs reach the mid-40s, but cold air lingers near the surface. That balance keeps a rain-to-snow change in play late Tuesday into Wednesday, particularly if precipitation lingers after sunset.
Drivers should watch timing closely. Wet roads could refreeze quickly once temperatures slide back toward freezing Tuesday night. Bridges, ramps, and untreated side streets will ice first. Allow extra travel time and slow down, especially during evening drives.
Wednesday trends drier and calmer as Christmas Eve approaches. Skies turn partly sunny, with highs near the upper 40s. While no major storm is expected locally, this system offers an early winter tease. Cold mornings, melting snow, and refreezing pavement remain a recurring risk.
Winter weather patterns are locking in across the Northeast. Even small shifts could change impacts fast. Traveling for Christmas this week? What are you seeing on the roads?
