UPDATE 10 A.M.
It's mid-morning and the dangerous wind chill values are still in place across all of Minnesota, although they should be dropping through mid-afternoon before they start to plummet again before winds decrease overnight into Thursday morning.
The coldest temperature recorded in Minnesota was a -70F reading in Ely earlier this morning, although that number is in question because they've been having issues with their sensor overdoing wind speeds, according to the National Weather Service.

Even with calm winds it'll still be extremely cold on Thursday morning with lows dipping close to -30F in the Twin Cities for a second consecutive day. The official low temp at MSP Airport today was -28F.
Even a 5 mph wind with an air temp of -28F will produce a wind chill of -43F. For example, at 10 a.m. today it was -35F in International Falls but a 7 mph wind gave them a wind chill of -55F.

Original story (7 a.m.)

Ponsford is located northeast of Detroit Lakes in Becker County, which is where some of the coldest wind chills were recorded.
Look at some of these unbearable readings the National Weather Service released as of 8 p.m. Tuesday – we'll revise this list as updated temperatures come out on Wednesday.

It may have dropped even lower in some parts of the state after 8 p.m., but those numbers haven't been released just yet.
The wind chill was observed as low as -55F at the official Minnesota-St. Paul International Airport. The actual air temperature in the Twin Cities (MSP Airport) at 7:20 a.m. was a numbering -28F with a wind chill of -50F.
This cold spell will stay in place all day Wednesday and through Thursday morning as the overnight low is again predicted to drop to near -30F.
The good news is that winds will be lighter so the wind chill values should stay in the 25-40 below zero range for the metro and gradually warm on Thursday.
By Sunday, you'll be wearing shorts and outside grilling as temps will surge into the 30s with a forecast high of 45 in the Twin Cities on Super Bowl Sunday.
