The US has been hit with crazy-cold temperatures this week, with schools closing across the country as people bundle up to brave the chill. Right on the heels of Winter storm Hercules, the weather has taken a very, very cold turn. In Downtown Chicago, temperatures dipped to -16 degrees Fahrenheit, marking dangerous cold the city hasn't seen in nearly 20 years. There, commuters wore ski goggles and face masks to walk through the city streets, with the wind only making matters worse thanks to local windchills of -45. Other parts of the country are feeling the frozen effects, too, with icy weather reaching Louisiana. Try to keep warm as you take a look at these photos of the frigid US!
