Maybe that's just me, but I can think of an instance where we had a tornado
I can see if it is a tornado. It has to be ready to touch right by my area though. A thunderstorm? That can be flashed accross the bottom. He even cut in at 7:30 to warn about a thunderstorm warning that lasted until 7:45. Yup, thats right, he came on to warn me about a thunderstorm warning that was going to be over in 15 minutes!
