Havent really seen any thunderstorms, lightening down here in London myself and ive been here near on 20 yrs now.
Growing up in Canada, mother of god we used to get some tremendous lightening and thunderstorms. I remember one lightening strike that when it hit, counted it to be about a mile away was so brutal it actually shook the house

. But i was in Canada last summer and we got some really hot, humid weather...hit about 38c in the day but late evening i was sat outside my brothers house having a cig and what a lightening and thunderstorm turned up...was pure awesomeness.
