Arctic Blast and Polar Vortex Bring Life-Threatening Cold and Snow Across U.S.

A severe winter storm is delivering dangerous cold, heavy snow, and travel disruptions from the Plains to the East Coast, with rare snowfall expected in the South.

Temperatures as low as minus-55°F with wind chills are forecast in the Plains and Upper Midwest, creating life-threatening conditions and risks of frostbite within minutes of exposure.
Heavy snow is expected along the I-95 corridor, with up to 10 inches predicted in cities like Philadelphia, New York City, and Boston, causing hazardous travel conditions through Monday.
The South, including Texas and Louisiana, faces an unusual winter storm bringing snow, sleet, and freezing rain, prompting states of emergency and warnings of significant disruptions.
Chicago and other parts of the Midwest are experiencing dangerous wind chills and sub-zero temperatures, with warming centers opening to assist vulnerable populations.
The polar vortex disruption is driving this Arctic outbreak, with scientists linking such events to atmospheric changes and ongoing climate research.
