London tornado

I was in London on Thursday, the day of the tornado. I was in London with the whole family on one of our exhausting days of touring. We were near the Tower of London when I saw the sky darkening to the northwest. A few minutes later and we were in the middle of a good thunderstorm. Thunder and lightning, but nothing that I would have considered extreme. No hail, no vicious winds such as I've experienced during severe storms at home. I couldn't believe it when I saw some evening papers later that day talking about homes wrecked by a tornado only five miles from where we were walking around.
