Philly sees more abnormally warm winter days

Winters in Philadelphia are increasingly getting warmer, according to data from Climate Central.

Why it matters: Analysis from the independent climate research organization suggests global warming is significantly shifting weather patterns across the country.

• Winter has been the fastest-warming season in most of the U.S. since 1970.

State of play: Philadelphia has seen abnormally warm winter days increase by 18 days since roughly 50 years ago.

• The average winter temperature is also nearly five degrees warmer compared to 1970.

Zoom out: This isn’t unique to Philly. The Northeast and the Great Lakes region see the fastest rate of warmer winters, per Climate Central.

Of note: Researchers at Climate Central reviewed more than 50 years of winter weather data in 246 locations across the country.

Flashback: Fall is also getting warmer.
