Arctic freeze continues to blast huge swaths of the US with sub-zero temperatures

PORTLAND, Ore. (AP) — A dangerous Arctic blast will continue sweeping across the U.S. and prolong a bitter cold that has set record-low temperatures in parts of the country and threatens to further disrupt daily life, including an NFL playoff game and the first-in-the-nation presidential nominating contest in Iowa. The National Weather Service says wind chills are expected to push down temperatures through at least midweek, possibly to 30 degrees below zero from the Northern Rockies to northern Kansas and into Iowa, testing the hardiness of caucusgoers willing to brave the deep chill on Monday (Jan. 15, 2024). Arctic storms have left at least four dead and knocked out electricity to tens of thousands in the Northwest, brought snow to the South and walloped the Northeast with blizzard conditions.
