It's set to be colder in many parts of the mid-west than it is on the surface of the planet Mars, and here's why. It's called a "Polar Vortex", and it's a very rare, climatic phenomenon in today's weather patterns. They usually only exist at the North or South poles and very rarely do they affect North America.

Almost half of the population of the United States will see temperatures plunge to record breaking and dangerous lows for the next few days. Our area is under a Wind Chill Warning beginning at 12 noon today and continuing through 7am Wednesday.

The National Weather Service warns that the next few day's temperatures could be "life threatening" as the Weather Prediction Center warns of a "dangerously cold air mass."
