Pennsylvania – A sharp winter chill grips the Delaware Valley this morning as dry pavement glints under pale sunlight. That calm, crisp start hides a fast-approaching shift. An arctic surge is pressing east, setting up snow chances, biting winds, and hazardous cold across the Philadelphia region by the weekend.
According to the National Weather Service, a reinforcing arctic air mass will drop into the Mid-Atlantic late Friday and Saturday. Light snow is possible Friday afternoon into Friday night, with higher chances after sunset. Snow totals look light, but timing matters. Temperatures fall quickly, increasing the risk of flash freezing on roads and sidewalks.
Friday brings increasing clouds and a high near 31 degrees. Snow may begin after midday, then become more likely into the evening. Any accumulation, even under an inch, could cause slick travel on I-95, I-76, Route 1, and local bridges. Drivers should expect patchy reduced visibility and icy spots.
Saturday turns colder and blustery. Highs struggle near 20 degrees while northwest winds add an extra bite. Snow showers linger early, then taper, but slushy patches may refreeze as temperatures drop. Pedestrians should watch for icy steps and untreated walkways.
Sunday stays bright but cold, with highs near 21 degrees. Wind chills remain uncomfortable, though conditions gradually improve. The bigger change arrives next week. NOAA’s 6–10 day outlook points toward above-normal temperatures returning by midweek, signaling a possible February thaw after this cold snap.
Plan extra travel time Friday evening and Saturday morning. Dress for the wind and cold, and protect exposed skin. Heading out this weekend? Let us know what conditions you’re seeing where you live.
