Our site and station are both a hobby and experiment in weather-related computing.

WEATHER FACTS
WHAT CAUSES THUNDER?
Thunder is caused by lightning. When a lightning bolt travels from the cloud to the ground it actually opens up a little hole in the air, called a channel. Once then light is gone the air collapses back in and creates a sound wave that we hear as thunder. The reason we see lightning before we hear thunder is because light travels faster than sound!
