Snow is expected to blanket Philadelphia this Friday evening

The Philadelphia region is experiencing its first significant taste of winter as winter officially began at 4:21 a.m. on December 21, 2024. The day started with a chance of snow in the evening, creating a damp and chilly atmosphere. As temperatures dropped closer to freezing, the chance of snow showers increased, particularly in areas such as upper Montgomery, upper Chester, and the Lehigh Valley, where accumulations of 1 to 3 inches were expected. The surrounding areas, including the Poconos, faced a more substantial snowfall of up to 5 inches. This transition from rain to snow has caused a slow evening commute and prompted residents to prepare for severe cold in the days ahead. After the snow dissipated early Saturday morning, the weather is expected to clear, revealing bright sunshine but plunging temperatures that will feel particularly harsh due to wind chills dipping into the teens and twenties. Cold air is moving across the region as northwest winds pick up, leading to the coldest temperatures observed this season by Sunday morning, with conditions forecasted to remain frigid throughout the weekend. The entire region is urged to take precautions, especially regarding the welfare of pets, as the frigid air may pose challenges for them as well. As winter settles in, the 7-day forecast indicates a series of cold days ahead, with high temperatures struggling to rise above freezing. During the week, as Christmas approaches, residents can expect more mixed weather with the possibility of rain returning by Christmas Eve, although temperatures are anticipated to be closer to normal by the holiday. Overall, this winter season is starting with a robust introduction of cold and snow, reminding residents to bundle up and brace for the season's challenges.
