Philadelphia, PA – The air in Philadelphia feels sharper this morning, a sign that December’s chill has settled in for good. Sunshine may hold through today, but meteorologists warn the pattern is shifting fast — with a chance for snow and a brief wintry mix by Friday morning that could slick roads just as early commuters hit I-95 and Route 1.
According to the National Weather Service, highs near 40°F today will give way to a colder push by late Thursday, with clouds thickening through the afternoon. By Friday, a narrow band of light snow could move through southeast Pennsylvania, bringing the first measurable flakes of the month. Forecasters say precipitation totals look minor — likely less than an inch — but any early snow or light freezing rain could still impact bridges and shaded roadways.
Drivers are urged to plan extra time for travel Friday morning, especially across Bucks, Montgomery, and Delaware Counties where black ice may develop as temperatures hover near 32°F. Even small accumulations can turn untreated surfaces slick fast.
By Saturday, skies clear and highs rebound to around 41°F, though the breeze will keep the air feeling raw. Sunday remains partly sunny before another dip in temperatures early next week hints at more December cold — and possibly another light snow chance by Tuesday.
