Some call that heat lightning, but it is really lightning that is over 15 miles away and too far away for you to hear the thunder! LOOK OUT if you see the lightning and hear the thunder at the same time!
New lightning data showed that most CG flashes in a storm were within 5-6 miles (8-9.6 km) of the previous flash. The LSG recommended what has become known as the 30/30 Rule. Using the flash-to-bang method, lightning that has a 30-second count between the flash and the thunder is 6 miles (9.6 km) away.
