A brutal Arctic blast is approaching the United States, fueled by a triple-dip polar vortex threatening to plunge temperatures across the Midwest and Northeast to dangerous lows. Record cold is expected, with projections indicating that several states may see temperatures drop 20 to 30 degrees below normal. The chilling air is anticipated to bring heavy snow and icy conditions, creating hazardous travel situations, particularly in the Mid-Atlantic and parts of the South. As the week progresses, meteorologists warn of significant snowfall and dangerous icy roads, with the Northeast bracing for some of the most extreme cold on Earth before Christmas. Residents are advised to bundle up and prepare for potentially record-breaking low temperatures as winter settles in.
