Can You Believe This Weather?

I know I have been talking a lot about the weather, but in the winter, what else is so versatile? When I arose yesterday the actual temperature was -2 degrees, with a windchill of -11. This morning it is +40 degrees. What gives? I don't see fog in our backyard, but know that it will be a problem as the snow still blankets the ground. If this warm weather continues into Monday, we could have a 2-hour delay due to fog. GRRRR! We need to go to school to learn at some point in this year!
