Bolt from the blue

Bolt from the blue

:"For the athlete referred to by the same name, see Usain Bolt"A bolt from the blue is a form of lightning that strikes out of an apparently cloudless sky. In fact, it actually originates from the anvil cloud atop a thunderstorm which may be as far as thirty miles away. It carries around ten times the current of an ordinary bolt of lightning and has a positive charge while most other lightning has a negative one. This commonly is known as positive lightning.
