Philadelphia, Pennsylvania – A sharp winter chill greets Philadelphia as temperatures dip into the upper 20s early, bringing visible breath and a biting feel to the morning air. While roads appear dry at first glance, changing conditions over the next two days could create travel hazards, especially for commuters and holiday travelers moving in and out of the city.
According to the National Weather Service, early-morning temperatures sit near 28 degrees, with wind chills in the low 20s. A gradual warm-up is expected through the day, but cold surfaces and shaded areas may remain slick during the morning commute.
Cold Morning Conditions Set the Tone
Philadelphia’s streets, bridges, and elevated roadways start the day cold and unforgiving. Even without snowfall, residual moisture from previous nights can freeze on untreated surfaces. Bridges, overpasses, and shaded stretches of road are the most vulnerable early on.
Drivers are urged to reduce speed during the morning commute and allow extra stopping distance. Pedestrians should also remain cautious, as sidewalks and transit platforms may hold patches of ice that are not immediately visible.
Gradual Warm-Up Brings Temporary Relief
By late morning and into the afternoon, temperatures climb into the low 40s, offering a short break from the deep chill. Sunshine filters through at times, helping main roads dry out. Despite the improvement, colder ground temperatures mean some spots may remain slick longer than expected.
This brief calm period is important, as it sets the stage for the next weather change moving into the region.
Rain Returns as Milder Air Moves In
On Thursday, a surge of milder air pushes into eastern Pennsylvania. Afternoon highs approach 50 degrees, signaling a transition away from the early freeze. However, that warmth also draws moisture northward.
By Friday morning, rain chances increase across the Philadelphia metro area. Showers become more widespread by midday, coinciding with heavier travel periods. South winds may gust over 30 mph, reducing visibility during stronger bursts of rain.
Major corridors including I-95, I-76, Route 1, and key local arterials are expected to see wet pavement and slower traffic during peak hours. Travelers heading to Philadelphia International Airport or beginning holiday trips should plan for delays.
Visibility and Travel Concerns During Friday Rain
While flooding is not expected locally, periods of moderate rain could briefly reduce visibility, particularly during the afternoon and early evening. Spray from vehicles, gusty winds, and changing light conditions can make driving more stressful than usual.
Motorists are encouraged to use headlights in rain, maintain safe following distances, and check flight or transit updates before departing.
Rapid Temperature Drop Raises Refreeze Risk
The biggest concern arrives Friday night. As rain exits the region, colder air rushes back in. Temperatures are expected to fall quickly into the upper 20s, creating ideal conditions for black ice.
Wet pavement can refreeze rapidly after sunset, especially on parking lots, ramps, side streets, and untreated roads. These areas often become slick before main highways show any warning signs.
Early Saturday morning travelers should be alert for sudden icy patches, even if roads appeared clear the night before.
A Broader Winter Signal for the Region
Although snow is not forecast for Philadelphia through the weekend, the pattern points toward a more active winter setup. Strong winter storms impacting parts of the Midwest often precede colder air pushing eastward.
Forecast models suggest colder conditions may persist into next week, increasing the likelihood of additional winter weather events as December progresses.
Five-Day Philadelphia Weather Outlook
- Today: Partly sunny, high near 43 degrees
- Thursday: Partly sunny and milder, high near 50 degrees
- Friday: Rain likely, breezy, high near 55 degrees

What Residents Should Do Now
Philadelphia residents should use the dry periods wisely by preparing vehicles, checking tire pressure, and ensuring windshield washer fluid is filled. Holiday travelers should monitor forecasts closely and be ready for rapidly changing road conditions late Friday into Saturday.
Staying informed and adjusting travel plans could make a significant difference as winter begins to tighten its grip on the region.
