"U.S. Braces for Record Arctic Blast with Dangerous Temperatures and Wind Chills"

An arctic blast is bringing record-low temperatures and life-threatening wind chills across the US, with snow and freezing rain spreading from the South into the Northeast. Over 120 million people are under wind chill alerts, and at least five deaths have been reported. Icy roads are making travel dangerous, leading to school closures in several states. The Northeast is bracing for heavy snowfall, while the Pacific Northwest faces an ice storm warning. Sub-zero wind chills are causing frostbite concerns, with temperatures expected to moderate midweek before another surge of colder air arrives.
