Apparently, we in the UK have more tornadoes per square mile than the US, they're just much smaller (the occasional wrecked roof or chimney).
Years ago, my mother and a friend were holidaying in the US, and saw a strange cloud down the highway. They drove after it in curiosity, not realising that it was a tornado until it spun the car around!
It must in in the family, because when I first moved to this part of the UK, a thunderstorm struck the town we were staying in. I climbed to the top floor of a multistory car park to watch the lightning as it struck the sea. It took me a while to realise that I was looking down on the strikes, standing in the pouring rain on the roof of the tallest building in the area...
Years before that, when we were courting, MrsBoast and I had a memorable sex session in a car parked in the countryside as a thunderstorm walked on legs of lightning down the valley, striking near-by on both sides of the car as it past.
