Made it down to -27F last night, but there were colder places to be sure. One town recorded -33F last I checked, and the night wasn’t over yet. I hope our Canadian brethren are holding up well.
Even with the heat cranked up, at -20F it’s still chilly in my building. Deeming caution to be the better part of valor, I cancelled a doctor’s appointment for today.
-24C here this morning. It’s warmed up to a balmy -20C, but with a nasty wind. Not unprecedented, and not as bad as you’re getting, but still wicked cold as far as I’m concerned. At these temperatures, going outside is scary. There’s an extreme cold warning for Manitoba and major chunks of Saskatchewan, Ontario, and Quebec. It’s -33C (-27F) in Winnipeg.
And maybe that’s why they call it “Winterpeg”, eh? 
-11F (-23.9C), now. How strange to call that “out of the woods”.
I used to drive extremely iffy cars and would do just that both in and out of town and my kids do the same. I still make them carry a parka and a pair of boots in their trunks through some parental jedi mind trick. Even though they are in their own cars in their twenties and think I am being overly concerned, they humor me.
Though, last year when my daughter slid off the road into a snowbank we both realized how far away your trunk is if you can’t open your car doors. Fortunately for her the tow truck was only a half hour away. As we were loading his car for my son’s drive back to Minnesota from Chicago after Christmas I found myself saying, “How 'bout you pop those boots in the back seat?”
That way they’d be a heckuva lot warmer, too.
Okay, it was only -27F to 37F, but who’s counting. That’s still a shift of 64 degrees or so in practically no time at all. It’s Minnesota, so no doubt some of the more valiant types will even be wearing shorts today in celebration.
