-15 here. Supposed to get to -5. Sun is out and wind has calmed, It’s not brutal like is was around daybreak. -60+ wind chill. You can’t even breathe in that. 5 minutes to frostbite.
Here in southern UT the high today will be 57 degrees with a full sun. I used to live in Chicago. There are many, many reasons why I thank God I do not have to live there.
