What's ahead for this week? Just in case you're one of the few who haven't heard: cold. Extreme, three-pairs-of-socks cold with the possibility of three consecutive days below zero.

And, what does that have to do with high school sports? Well, Gov. Tim Walz has already gone on record as saying he'll explore the possibility of closing schools because of dangerously cold temperatures, as Gov. Mark Dayton did in 2014 and Gov. Arne Carlson did in 1994. And closing schools means postponing games.

So, go ahead and make plans to attend a sporting event this week. Just be aware that those plans might change.
