In this video, you'll witness a rare kind of lightning strike, called a bolt from the blue. Basically most lightning strikes are negative strikes that occur under the cloud base. Only 5% of lightning strikes are positive strikes that come from the upper parts of the cloud. Many of these strikes are cloud-to-cloud, but some of them do make it to the ground, especially in a rapidly strengthening thunderstorm. This comes to show that a thunderstorm does not have to be in progress over your area for there to be a lightning hazard. These positive strikes can occur up to 10+ miles OUTSIDE the thunderstorm.
