Arctic Air Mass Brings Deep Freeze to U.S.

An arctic air mass is set to bring a significant drop in temperatures across much of the U.S. this weekend and into next week, with some areas experiencing a 30 to 40-degree plunge. Rain is expected to begin on Saturday, followed by a rapid temperature decline, leading to dangerously cold conditions from the Midwest to the East Coast, with wind chills potentially reaching 30 to 50 degrees below zero. This deep freeze could lead to hypothermia and frostbite risks, particularly in the northern Plains and Midwest, where temperatures will remain in the teens or lower. Southern states like Texas and Georgia will also experience the cold, with temperatures dropping into the 30s and below freezing at night. Snow accumulation is expected in the Rockies and Colorado's high country, with significant snowfall over the MLK weekend. As the cold persists into next week, forecasters are closely monitoring a potential coastal low that could bring further precipitation and cold conditions.
