Pennsylvania – Damp streets reflect headlights this morning as cold air settles across the Delaware Valley. Light flakes mix with drizzle at times, leaving sidewalks wet and drivers cautious. It feels quiet now, but winter signals are stacking up as post-Christmas travel approaches.
According to the National Weather Service in Philadelphia, temperatures hover in the upper 30s early, with spotty snow possible before a daytime warm-up pushes readings into the 40s. Any snow accumulation remains minor, yet melting during the day sets up a familiar December problem once colder air returns.
Across southeastern Pennsylvania, including Philadelphia and nearby suburbs, conditions turn breezy and cooler midweek. Dry weather briefly returns, allowing roads to dry. That window closes by Friday, when another system approaches with a renewed chance of snow developing during the afternoon. Rain may mix in early, then transition back to snow as temperatures slide toward the mid-30s.
Travelers using I-95, the Schuylkill Expressway, and Route 76 should prepare for reduced visibility and slick stretches late Friday. Wet pavement can freeze quickly after sunset, increasing black ice risk on ramps and bridges. Even light snow can slow traffic during peak holiday returns.
Looking ahead, winter weather remains a theme into the final stretch of December. A milder pattern competes with colder air, creating repeated freeze-and-thaw cycles. That keeps flash freezing on the table whenever snow or rain lingers into evening hours.
Drivers should plan extra time, keep headlights on in snow, and watch shaded roads closely. Conditions may change quickly as systems track along the Mid-Atlantic corridor, and additional alerts could be issued.
