I remember that. Was working nights when the -50 wind chills hit. I didn't think it was all that bad at the time but I was young and dumb then.The temperature on my back deck hit -4*F on January 7, 2017 (I only know that because I took a couple of pictures of my indoor/outdoor weather station). I remember it getting bitterly cold back in '83 or '84, but I don't recall how cold it was. It was cold enough that when I was in my dad's car, even after it had warmed up it still looked like I was smoking when I exhaled...
