Philadelphia upended by first snowstorm of 2025

The big picture: Philadelphia has experienced a mild winter so far, registering only three-tenths of an inch of snowfall before Monday's storm dumped several inches across the region.

• Global warming has affected snowfall totals across the U.S., with nearly two-thirds of more than 2,000 locations getting less snow than they did in the early 1970s, per a Climate Central analysis.

By the numbers: Snow totals reached nearly two inches in parts of the city. Parts of Delaware and New Jersey saw almost nine inches and seven inches, respectively, per the National Weather Service.

• Hundreds of flights were delayed or canceled at Philadelphia International Airport on Monday, per Flight Aware.

Stunning stat: The most snow Philly's had on Jan. 6 — 5.1 inches — came in 1989.

What's next: A cold snap, with temperatures expected to remain below freezing, will last through at least Friday, Climate Central meteorologist Lauren Casey tells Axios.

• There's a 30% chance for snow on Saturday, which could make for bitter conditions at the Eagles' playoff opener against the Green Bay on Sunday at Lincoln Financial Field.

The intrigue: Philly hasn't seen a weeklong stretch of temperatures at or below freezing since 2017-18, Casey says.

• The city's longest sub-freezing streak is 15 days, which occurred twice in February 1961 and February 1979, per Casey.

What they're saying: "It's generally rare. We don't stay that cold for that long in Philadelphia," Casey says.

What's ahead: More flakes are likely in February — typically the snowiest month of the year, registering an average of 8.4 inches.
