Colorado lightning safety awareness week continues through this
Saturday. Today we discuss the science  of lightning.

Every thunderstorm produces lightning. Lightning is a giant spark
that moves within the clouds, between clouds, or between the clouds
and the ground. As lightning passes through the air, it heats the
air rapidly to a temperature of about fifty thousand degrees
Fahrenheit. This causes a rapid expansion of the air near the
lightning channel. This rapid expansion causes a shock wave that we
hear as thunder.

For more information on the science of lightning, point your web
