Pennsylvania – The air bites hard this morning, stinging exposed skin and frosting windshields before sunrise. Side streets glisten, breath hangs thick, and every step feels louder on frozen pavement. Winter has full control early today, and conditions remain risky through the morning hours.
According to the National Weather Service in Mount Holly, a Cold Weather Advisory remains in effect until 10 a.m. for southeastern Pennsylvania, including Philadelphia. Wind chills have dipped as low as zero, with some nearby areas slipping below. Gusty northwest winds continue to drain warmth quickly, increasing hypothermia risk without proper protection.
Across the state and into New Jersey, arctic air presses southward as the Great Lakes remain heavily frozen. That locked-in ice cover limits moisture but reinforces cold, allowing even minor snow chances to matter. Philadelphia sits on the edge of that boundary, where small changes can impact travel.
Later today, sunshine helps slightly, but temperatures struggle to climb out of the 20s. Any melting on roads or sidewalks may refreeze quickly after sunset. This is prime flash-freeze territory, especially on bridges, I-95 ramps, and untreated neighborhood streets. Plan extra time if driving tonight.
By Tuesday, conditions moderate just a bit, with highs near the mid-30s. Clouds increase by evening as a fast-moving system approaches. Light snow becomes possible late Tuesday into Wednesday morning. Accumulations look minor, but timing favors the morning commute. Slushy spots and reduced visibility could slow traffic.
Wednesday turns partly sunny but remains cold, keeping refreeze concerns active. Another snow chance appears Friday, reinforcing an active February pattern. Looking farther ahead, signs point to a warmer trend late next week.
For now, layer up, limit early travel, and watch pavement closely after dark. Feeling the cold where you are? Let us know what conditions look like in your neighborhood.
