NEGAUNEE TOWNSHIP, Mich. (WLUC) - For many cities in the U.P., the final week of December broke all time records.
Ironwood for example, recorded three consecutive nights below -20.
Other cities broke records for holding the coldest Holiday week on record.
In addition to the frigid cold, wind chills all across western Upper Michigan felt closer to 40 below zero.
With wind chills this cold, frostbite can occur in just minutes.
"It's even colder in Canada and farther out west in the Dakotas and Minnesota," said Meteorologist Brett Borchardte. "We're lucky to have Lake Superior to keep us a little warmer. In the Dakotas, like Fargo, they have had wind chills close to -50 degrees. So it's been very, very cold across the northern U.S."
Just a reminder, it's never too late to update your emergency supply kits, especially in your car.
Because unfortunately, the weather isn't looking much warmer for the skiers this weekend in Ironwood.
