'Steam Devil' Video: Frigid Air Causes Steam to Wash Over Lake Michigan

01/07/2014 at 11:00 AM EST

Along with snow and sub-zero temperatures, the punishing polar vortex is causing some strange side effects throughout the United States.

This clip may look like a live feed from Dr. Freeze's secret tundra lab, but it's actually recent footage from Chicago's Navy Pier. As the polar vortex moved into Illinois on Monday, it created a weather phenomenon known as a steam devil.

A steam devil is the result of frigid weather meeting with warmer water – in this case Lake Michigan – and humidifying the water into steam.

There may be some steam in Chicago, but things are far from hot. Current weather conditions in the Windy City are also leading to some seriously stunning ice build up along Lake Michigan (see below).
