Electrons in the bottom of the cloud are attracted to the protons in the ground. When the connection is made the protons rush to meet the electron and that is when you see lightening. A bolt of lightening heats the air along its path casing it to expand rapidly. Thunder is the sound caused by this rapid expanding air.
