Massive Winter Storm Threatens US with Heavy Snow, Ice, and Arctic Cold

• A powerful winter storm, potentially the most disruptive of the season, is set to impact a vast stretch of the US from the Southern Plains to the East Coast.
• Forecasters predict heavy snow, with up to a foot possible in cities like Kansas City, St. Louis, Louisville, and Washington D.C., which could see its biggest snowfall in years.
• Dangerous freezing rain and ice accretion, potentially snapping tree limbs and power lines, are expected from Texas through the Carolinas.
• Widespread travel disruption is anticipated on major highways, including Interstates 40, 70, and 95, especially during the storm's peak on Sunday.
• An Arctic air surge following the storm could bring subzero temperatures to over 100 million people, with risks of life-threatening power outages, particularly in the South.

Why It Matters: A severe winter storm will bring heavy snow, crippling ice, and dangerous Arctic cold across a huge swath of the US.
