o below displays, cloud-to-ground lightning usually occurs near the boundary between the updraft region (where the darkest) clouds are, and the downdraft/raining region (with the lighter, fuzzy appearance). Sometimes, however, the lightning bolt can come out of the side of the storm, and strike a location miles away, seemingly coming out of the clear blue sky. This is called “a bolt from the blue”. As long as a thunderstorm continues to produce lightning, you know that the storm still has active updrafts and is still producing precipitation. The temperature inside a lightning bolt can reach 50,000 degrees Fahrenheit which is 5 times hotter than the surface of the sun.
