Where's winter?

Christmas mood knocks on my door at last. But where on earth is winter? There's +10°C these days, and still there's no snow. It seems like it's october now. :D
Second time I've got lessons on Christmas, that's unfairly. As you probably guess, this happens because people here have their holiday on 7 January (orthodox christmas, after new year).
Btw, I am ashamed that I had no idea that this song based on a ukrainian folk chant. :)
