Just had this conversation yesterday with oldest daughter (who just had her first child).

Daughter: Dad I am glad you taught me that tornados are no big deal and you should just stay calm.

Me: I only LOOKED calm, and that was just to not freak you out and your little brother and sisters. Every time the sirens went off we took you guys to the basement. When I said I was going back up to get the dogs, I ALWAYS got on our local TV channels to get the doppler radar reports of the spotted tornado plus the analysis of the areas that might spawn new tornados. Only after that did I bring the dogs down. Do NOT be clueless, but rather always get more info to see if one is truly coming your way.

We then had a long conversation about getting more information and evaluating your risk.

We have looked at tornado clouds in the distance, and seen what they look like during the day. However, "rain-wrapped" tornados and night tornados can only be prepared for by modern scientific analysis.
