-50 from the Minnesota River basin.
Heck, down near St Louis, the wind chill now is -7. I can vouch for that, having been out to feed birds, cats and horse. (And yes, I would bring all the feral cats inside if I could catch them! Have set up snug areas for them in several places, and I see faces when I look at them.)
