Thank you for that information, John. I have gold-starred your posts so that I have quick access when I need it. We don't get many tornadoes here -- we live in a large valley area, flanked by the Mississippi and Ohio Rivers. Seems like when a strong weather system hits the juncture of those Rivers, it is inclined to ride the north ridge of the Ohio River, and goes up (north) and past us. Thankfully. Of course, that didn't happen for the ice storm of 2009, sadly -- but that was a real oddity.
