You've probably heard of Hallock, Minn., only if you check the continental U.S. temperature extremes regularly, as I do.
Yesterday, Hallock tied its all-time low for the date at -19 degrees.
It warmed up to +1 in the afternoon.
As I write this, it's a balmy +5 with light snow falling, so the cold snap apparently is over.
Hallock is way up in the northwest corner of Minnesota, near the border with Canada and the North Dakota state line. I'm sure it's a lovely place to visit, except between November and April.
