As a severe cold wave approaches, over 100 million people are on alert for dangerous temperatures, with some regions expecting the coldest wind chills of the season. The Northeast is bracing for a weekend marked by persistent cold fatigue, strong winds, and snow, particularly in New York City, which is anticipated to experience bitterly low temperatures and several inches of snowfall. Authorities are urging residents to prepare for extreme conditions, including below-zero wind chills that could reach as low as -20°F. Cold weather advisories cover much of the region, including specific warnings for Central New York and nearby counties. New Yorkers have been advised to wear face masks and avoid unnecessary travel as this Arctic blast is expected to culminate with record-breaking lows before a gradual warm-up is forecasted in the near future.
