Snow overnight brought less than an inch to the metro by Saturday morning. That made for some slick driving conditions around the Twin Cities.
Emergency officials are warning of another Arctic surge that's expected to sweep across the Midwest this weekend. The temperature drop is expected to begin around 6 a.m. Saturday, along with strong winds.
Monday's temperatures could be the coldest since 1994, according to Meteorologist Dave Dahl. He expects Sunday night's low to be 24 degrees below zero. The highs both Sunday and Monday will remain below zero. Wind chill readings could plummet to 60 degrees below zero Monday morning.
Emergency officials say those conditions could lead to major trauma in a matter of minutes. Frostbite can occur on exposed skin in less than 10 minutes, and people are especially vulnerable to hypothermia, which is marked by shivering and confusion.
Officials also remind residents to keep pets indoors.
The deep freeze in Minnesota and Wisconsin is breaking records, even before the coldest air of the season arrives next week.
The temperature plunged to 43 below zero in International Falls in far northern Minnesota early Thursday. Friday morning the mercury hovered around zero in the city that hugs the Canadian border. National Weather Service meteorologist Kevin Huyck says Thursday's temperature in International Falls breaks a record set in 2010 when the mercury dipped to minus 37.
In St. Louis County, readings dropped to 36 below in Embarrass overnight Thursday and 33 below in Ely.
A record-low temperature was set in Green Bay on Friday morning, where the mercury dipped to minus 18. The National Weather Service says that tops the 17 below mark last recorded in 1979.
Antigo, Wis., also set a record Friday at -25, that's without the wind chill factor. A previous record of 22 below was also set in 1979. The weather service has posted a wind chill warning from 6 p.m. Sunday to noon on Tuesday as even colder air arrives.
This cold snap is bringing back memories of Gov. Arne Carlson closing schools statewide in 1994, 1996 and 1997 due to frigid temperatures. You can track school closings with School Alert.
