We’ve talked about natural disasters before, but we definitely left out one big one: the tornado. Let’s correct that.

Amid the discussion about how tornadoes work and why they always hit trailer parks, we’ll talk about the history of tornado science, what '“F numbers” really mean, and explain why for 40 years tornadoes didn’t exist. It’s a complicated business, these tornadoes, and we’re all a-whirl to talk about it.
