The celestial spectacle known as the northern lights is unlikely to grace the skies of Chicago this week based on updated predictions, according to science experts. 

Also known as aurora borealis, the lights were initially forecast to be visible low on the horizon in Chicago and seen overhead in Minneapolis and Milwaukee, according to the Geophysical Institute at the University of Alaska-Fairbanks.
