The night sky could offer Wisconsin residents more holiday entertainment after Black Friday shopping is over: There’s a chance the Northern Lights will be visible again.

NOAA’s Space Weather Prediction Center issued a geomagnetic storm warning for Thanksgiving and Black Friday earlier this week. Such storms can cause the lights to appear.

“The Northern Lights could become visible over some northern and upper Midwestern states from New York to Idaho,” the watch said. “If you want to see the aurora, you should check our website for updates.”

When could I see the Northern Lights in Wisconsin?

The Northern Lights could be visible in northern Wisconsin Friday evening, according to a forecast from NOAA’s Space Prediction Weather Center.

Thursday’s forecast has a Kp index of three, meaning there may be more aurora activity. “If you’re in the right place, these auroras can be very beautiful to see,” says NOAA.

What tips are there for seeing the Northern Lights?

NOAA says the lights are typically at their best “within an hour or two” of midnight, meaning you should look for them between 10 p.m. and 2 a.m. If you want to catch a glimpse of the lights, you should move away from the city lights and seek out a high vantage point.

What will the weather be like on Friday evening?

After some likely severe weather throughout the day, northern Wisconsin is expected to be cool and mostly cloudy Friday evening, with a low of 13 degrees, according to the National Weather Service office in Green Bay.
