On the topic of weird weather, we've got a tornado warning tonight (in Ottawa). Who'd of thunk it?

We've got a really bad thunderstorm right now, and high temperatures for the past few days, but a TORNADO?!

I think everything will be fine, but the power better not go off ... I hate that sort of thing.

Is it a reasonable result of a series of hot days and thunderstorms to develop into a tornado?

Sorry, I'm just confused ... a tornado warning is a new thing for me
