Blowing up a Storm

We have 42 mph wind gusts today and it is blowing in warmer air. That means only one thing. Thunderstorms will be rumbling in tonight. I don't know why it always has to be at night when you can't see anything. We live in a mobilehome and it is kind of scary when the weather really gets rough. We have a good tornado shelter but we are never sure whether we or not it is time to go there.
