An Arctic storm spanning 1,500 miles from Florida to Maine brings snow and life‑threatening travel from Sunday, January 18, 2026, through Wednesday. Winter storm warnings cover Michigan, New York, Georgia, Florida, and Alabama as Arctic air and a disturbed polar vortex deepen. Forecasts note -50°C at 500 mb and wind chills near -25°F in Michigan, with rare Florida Panhandle snow, including Pensacola, threatening crops. Retailers in Georgia and the Northeast stock supplies, utilities brace for peak consumption, and natural gas jumps about 20% to $3.70 per MMBtu on January 19, 2026. Drivers winterize vehicles, health officials warn about dangerous wind chills, and authorities watch agricultural and infrastructure risks into late January.
