Winter outlook: A look at seasonal trends and what to expect in the months ahead

Winters have warmed by 3.9°F on average across 239 U.S. cities since 1970, according to an analysis from scientists and researchers at Climate Central. Winter is the fastest-warming season for most of the U.S. — affecting snowfall, water supplies, winter sports, spring allergies, summer fruits, and more.
