Temperatures are plunging across Minnesota with wind chills of between 35-45 below expected Sunday morning.
In the Twin Cities, air temperatures were at 19 below as of 7:30 a.m. and while the metro area hasn't had the worst of the wind chills, the National Weather Service said it hit -27 overnight.
Other areas of the state, like Alexandria, saw wind chills plunge to -45. It was expected to get colder through to sunrise, and daytime highs of 4 below are the best Twin Citians can hope for.
Here are some things to know if you're hiding indoors or daring to venture outside:
Some are without electricity
More than 3,000 properties are without power as of 7:45 a.m. Sunday morning, according to Xcel Energy's power outage map.
A few hundred of these are in the Twin Cities, but the worst-hit areas are west of the metro, in Dassel, Cokato and Winsted, where more than 2,000 homes have no electricity.
Xcel tweeted to a customer it expects to have power restored in those areas by 8:15 a.m.
Snow emergencies are in place
Friday and Saturday's snowfall, which saw more than 6 inches dumped on the Twin Cities, has prompted cities including Minneapolis and St. Paul to declare snow emergencies.
If your car is parked on the street, you need to check out the plowing schedules to make sure you don't get towed. Plowing is starting in both cities at 8 a.m. Sunday.
One of the victims of the extreme cold is the Holidazzle holiday village in Loring Park, Minneapolis.
Organizers sent out an alert Saturday saying it would shut up shop on Sunday "due to forecasted dangerous temperatures and wind chills."
To make up for it, it's extending its hours to noon-10 p.m. this coming Thursday and Friday.
The roads aren't safe
Although not as bad as Saturday, when metro area roads were covered in snow, the now partially-covered roads are still causing problems for drivers.
Here's a look at the traffic map at 6:30 a.m., showing several crashes and spinouts in the metro.
A section of Highway 212 in the southwest metro was closed on Saturday following a number of crashes, and the Minnesota State Patrol says road conditions remain hazardous as some parts of the road, particularly bridge decks and overpasses, develop ice.
Vikings fans heading to U.S. Bank
It's going to be a cold journey to U.S. Bank Stadium for the 60,000 Vikings fans heading out to see them take on the Colts – but hey, at least the stadium's now indoors.
Some incredibly dedicated fans are even planning on tailgating despite the insane temperatures, although the Star Tribune reports that others with spots plan on staying away.
Chris Corless is among those who will brave the temperatures, telling the newspaper he'll be packing an extra propane tank to keep his tent warm, and plans on getting to the stadium at 6:30 a.m.
For other fans, the skyway system will be open and can take you right to the stadium – here's a map:
Staying safe in the cold
If you do find yourself outside, make sure it's not for long and you don't have any exposed skin. According to the National Weather Service, it can take just 10 minutes for frostbite to set in at -35f wind chills, and just 10 minutes at -45f.
The weather service has a whole page of tips on staying safe in extreme cold, which you can find here.
Hennepin County meanwhile has been tweeting out locations of warming places and shelters for those caught in the cold today.
