Scientists predict a solar storm this weekend, meaning the people in Wisconsin might be treated to a northern lights display.
The National Oceanic and Atmospheric Administration expects a geomagnetic, or solar, storm to peak Saturday, with the aurora borealis potentially visible across the country from New York to Wisconsin to Washington state.
Aurora borealis (aka northern lights) are caused by electrons colliding with the upper reaches of Earth's atmosphere. There's an energy release in the form of light. In best-case scenarios for onlookers, splashes of pink, green, yellow, blue and violet fill the night sky. (For a more in-depth explanation, the NOAA has you covered.)
The National Weather Service forecasts call for clear or mostly clear skies Saturday night around Wisconsin. To get the best look, avoid cities or other areas with light pollution.
There's a chance the lights will be visible Sunday night, too, but it's less likely than Saturday.
