The Philadelphia region is preparing for a quiet but impactful winter event this weekend. An Alberta clipper will bring a light snowfall overnight, followed by a sharp drop in temperatures that could make roads and sidewalks treacherous.
A Quick Look at the Weather Outlook
Cloud cover is expected to increase across the area on Saturday, December 13. Daytime temperatures will hover in the lower 40s. Late Saturday night, a fast‑moving Alberta clipper will move into the region. Clippers are known for their speed and low moisture content, but this particular system is strong enough to produce a widespread, accumulating snowfall as we head into Sunday.
Snow Forecast
A light wintry mix will begin late Saturday night, quickly turning into all‑snow conditions that will persist through much of Sunday morning. Preliminary data indicates that the Philadelphia area will receive about 2 to 3 inches of fluffy snow. While not a major storm, the accumulation will be enough to coat roofs, trees, and street surfaces before most people wake up.
How the Snow Will Affect Daily Life
- Roads and sidewalks may be slick if the snow is not cleared promptly. Any remaining snow that is not shoveled or brushed away can freeze solid, creating hazardous conditions.
- Driveways could become slick and difficult to navigate.
- Public transportation routes may experience delays if tracks or platforms are covered in snow.
After the Snow: A Surge of Cold
By Sunday afternoon the snow will have largely melted, but frigid air will pour in behind the system. Temperatures will drop through the afternoon and into Sunday night. Gusty winds will make it feel like the teens during the game. Monday morning temperatures will fall into the teens, setting a frigid start to the work week.
The path the clipper takes is crucial. Sunday’s snow totals may shift as forecasters fine‑tune the forecast heading into the weekend. However, confidence is growing that residents will wake up to a fresh layer of powder early Sunday morning.
Impact on the Eagles Game
The cold snap could play a significant role for the Philadelphia Eagles’ Sunday afternoon game. With gusty winds and low temperatures, game day conditions may be slick, affecting player footing and ball handling. Fans and teams alike should prepare for a potentially chilly and slippery environment.
