Good question, Jim. But I used to help my mother work costumes for a theatrical troupe. If you expect actors to make sense, you are in for a disappointment.

Where I live, the weather is intense and variable. We have a superstition against saying what you hope for in the way of weather. For example, we would never say, "I hope it's nice for the picnic on Sunday," because that would tip Them off, and they will make it rain. Or perhaps send a tornado.

Most people don't actually define Them, but I call them the Weather Demons.
