I love the idea behind your website, I have family back in Montreal and I'm constantly comparing the midwest weather (tornadoes especially) to what I consider good ole fashioned Canadian weather. In all my years back home I can't recall many tornadoes maybe one or two but of course there's the ice storm, Saguenay flood and the famous flash flood in '87... i still prefer those over tornadoes...
