How severe are the wind chills expected to be during this winter storm?

According to Faith Abube, ABC News Correspondent, wind chills are expected to feel like 20 degrees below zero during this significant winter storm. This dangerous cold is part of a larger weather system affecting over 100 million Americans across 25 states, stretching from Montana to Texas. The extreme cold is particularly severe in Chicago, where temperatures could feel as low as 21 degrees below zero. These hazardous conditions, combined with snow and ice accumulation, have prompted officials to urge drivers to stay off roads and take necessary precautions as the winter storm continues to advance eastward.
