Hey Minnesota, northern lights may put on a show Thursday, Friday night

A geomagnetic storm may deliver a potentially awesome northern lights display the next couple of nights across Minnesota. If skies are clear, it could be something.

The National Oceanic and Atmospheric Administration's Space Weather Prediction Center says the "effects from a large coronal hole high speed stream" are expected to last through Friday before the intensity decreases Saturday.

That opens the window to much of Minnesota and northern Wisconsin to the wondrous spectacle:

If you need a definition, the aurora is a "luminous glow of the upper atmosphere caused by energetic particles entering the atmosphere from above," according to the University of Alaska, Fairbanks.

You can just call it "ooh" and "ah" tonight and Friday.
