Waking Up on the Wrong Side of the Sky by Chad Norman, Bruce Wood

Sometimes there is more in the sky than meets the eye. There is Chide, the tiny snow cloud, and Rove, the bully rain cloud. And below, one boy on girl, a sled and skis and a singing shovel, all waiting for snow. On the wet rainy cost there is never enough room for Chide. It's hard for him to find a place in the sky, even in the winter. Bully Rove just doesn't want to share. The sun is asleep, and something needs to be done.
