It's been a few years since I've said, "Hey kids! We're getting snow tomorrow--that means it's warming up!"
(Although in Alaska, my daughter still went out to recess until it was -20 degrees. Here, school is closed because it is currently -14. (The wind chill is -30 and even things in Alaska shut down at -30, so I guess I can't put down the school. The kids, of course, are thrilled!))
