If seeing the Northern Lights is on your bucket list, there's a possibility you'll be able to see them in the Chicago area if the weather cooperates. According to the Chicago Sun-Times:
"Out of the polar vortex, into the Aurora borealis. Quite an atmospheric week around here.
Northerners thawing out from a bitter freeze – including our Chiberia – may get rewarded with shimmering northern lights the next couple days.
Federal space weather forecaster Joe Kunches said the sun shot out a strong solar flare late Tuesday, which should arrive at Earth early Thursday. It should shake up Earth’s magnetic field and expand the Aurora Borealis south, possibly as far south as Colorado and central Illinois. He said best viewing would probably be Thursday evening, weather permitting."
