A potent Arctic blast is currently gripping the Midwest and Northeast, plunging temperatures to record lows. Millions are facing sub-freezing conditions as the polar vortex brings some of the coldest weather seen in decades. Iowa has reported record lows in at least 15 cities, while frigid temperatures are causing disruptions across various regions, including challenges for ski resorts that are delaying openings due to unusually warm weather earlier in the season. Snow is expected to return, contributing to hazardous conditions, especially in areas like Virginia, Maryland, and DC. The bitter cold is intensifying, with wind chills near zero, and impacts are expected to continue through mid-December, raising concerns for the entire eastern half of the country. As forecasters predict that a triple-dip polar vortex may affect states as far south as Texas, residents are advised to prepare for ongoing extreme winter weather.
