Meteorological events that happened on August 14th:
Lightning strikes can take many different forms. The reason crooked or forked lightning forms is due to the fact that as the precursor to lightning tries to work its way to the ground it searches for the path of least resistance. When the atmosphere has too much resistance a new path takes. By the time the strike makes contact with the ground it's path has often been altered many times.
