Residents of Chicago, Illinois, are enduring frigid temperatures as the polar vortex continues to sweep over the Midwest. Eric Gaydos filmed footage of what appeared to be steam or smoke rolling across Lake Michigan on January 30, not knowing exactly what he was recording. The freezing temperatures created a phenomenon known as sea fog, which occurs when a patch of cold air passes over warmer water. In this case, since temperatures in Chicago were so low, even the freezing water of Lake Michigan was warmer than the air above, and caused this interesting spectacle.
