The snow-making machines are purring and the lifts are up and running.

Just last weekend, people were water skiing in Minnesota. But now the weather is finally cold enough for snow skiing.

According to the Minnesota Ski Areas Association, many ski areas have opened or will be opening this weekend – and hopefully will stay open for the season. (See a list at the bottom of the page.)

That's thanks to the colder weather we've had this week, which allowed ski areas across Minnesota to make snow instead of waiting for Mother Nature to handle it. Most of central and southern Minnesota hasn't seen a major snowfall this winter, and the DNR's website shows there's no snow on the ground there, while northern Minnesota has seen a few storms, giving it 4-8 inches of snowpack as of Thursday.

Several ski areas opened for Thanksgiving weekend, but had to close because temperatures warmed and rain destroyed the snow they had made, Pam Hove, of Afton Alps, told the Star Tribune.

But there's good news coming. Snow is on the way Saturday, which could bring a few inches to southern Minnesota and help ski areas open additional runs.
