It’s rare for December to feel like a winter wonderland in Philadelphia, but this Friday the city is set to experience its coldest day in nine months. While early December usually brings mornings above freezing and daytime highs in the upper 40s, the upcoming weather pattern is poised to break that pattern. A cold front will sweep through Thursday, setting the stage for a sharp temperature plunge. The city’s residents can expect a chill that will test even the most prepared winter wardrobes.
The Cold Front
The cold front arrives on Thursday, pushing temperatures into the low 40s by afternoon. Gusty winds accompany the front, which will reduce the wind‑chill temperature to the lower 30s. As the day ends, the winds will ease, allowing the air to become very dry. This combination creates the perfect conditions for temperatures to drop rapidly overnight.
Friday Forecast
By Friday morning, the Philadelphia suburbs will wake to temperatures in the teens, while the rest of the region will see very low 20s. The forecast low for Philadelphia itself is 22°F, which sits more than ten degrees below the average for this time of year. Historically, the last time morning lows reached the 20s in Philadelphia was at the beginning of March. Even with this low, the day will not approach the record December 5 temperature of 13°F set in 1886.
This Friday will mark the coldest weather Philadelphia has seen in the past nine months. The drop in temperature will be felt most acutely in the morning, as the city’s streets and sidewalks will be slick with frost. Residents will notice that the wind, while not as strong as Thursday’s gusts, can still make the air feel significantly colder. The day will remain cold for most of the daylight hours, with a maximum temperature that tops out around 32°F.
Cold Weather Tips
Given the severity of the forecast, city officials recommend layering clothing to retain body heat. Extra layers help keep the core warm, especially during the early hours when temperatures are lowest. It is also wise to cover exposed skin and the face, as even a light breeze can increase the wind‑chill effect. Those traveling by car should consider packing an extra layer and a snack in case the trip takes longer than expected.
Weekend Outlook
Friday’s harsh cold will give way to a modest improvement over the weekend. Skies are expected to turn partly sunny, allowing temperatures to climb into the low 40s on Saturday and Sunday. Although still chilly for early December, this shift represents a noticeable step up from Friday’s frigid conditions. The warming trend, however, will be short‑lived as another cold front is projected to arrive on Monday.
Monday Cold Front
The Monday cold front will bring temperatures down again, reminding residents that the winter season is far from over. The brief respite over the weekend offers a welcome break, but the forecast indicates that the cold will return swiftly. This pattern underscores the importance of staying prepared for rapid changes in weather.
Safety Tips
If you must go outside, wear a wind‑proof jacket and thermal layers. Protect your hands with gloves, and keep your head covered with a hat or scarf. Use a face mask or scarf to shield your face from cold air. Check the weather forecast regularly for updates, especially if you plan to travel or run errands.
Final Thoughts
While the cold may be a challenge, it also offers a chance to enjoy the crisp, clear air that defines winter in the region. Residents can take advantage of the short window of warmer temperatures over the weekend to plan outdoor activities. Keep an eye on local news for any updates or advisories, and stay safe during the cold snap.

Residents should prepare accordingly, stay warm, and stay informed through reliable weather sources.
