Winter Weather

A weekend winter storm plunged temperatures well below zero across the Midwest and brought the season’s first significant snowfall to parts of the Northeast on Sunday, Dec. 14, 2025, while the Pacific Northwest—already hit by catastrophic flooding—braced for more rain and wind. The National Weather Service said about 63 million people are under cold weather advisories and 11 million under freeze warnings, with states imposing speed limits, cities plowing roads, and airlines reporting more than 1,000 delays and 100 cancellations.

About 18 million people across the West and Midwest are under winter alerts as an Arctic blast brings dangerously cold temperatures and wind chills; the NWS reported −12°F in Grand Forks, N.D., with a wind chill near −33°F late Saturday morning, and forecasts show lows around −15°F in Minneapolis and about 1°F in Chicago into Sunday. The cold air mass is expected to push south and east through the weekend, prompting cold‑weather advisories as far south as Montgomery, Ala. (≈22°F) and Savannah, Ga. (≈24°F) late Sunday into Monday.
