What causes the sound of thunder?

When cold dry air from the North, meet warm moist air from the south...
Thunder (which is the sound) comes from lightning (which is the flash).
Lightning is extremely hot (4 times the temp of surface of sun) it heat the air around it.
The heating causing the air to expand (remember PV=nRT) the rapid expansion causes a pressure wave (remember PV=nRT sorry I had to).
That pressure wave (sound is a pressure wave) is so intense we hear the "boom" when the pressure wave hits us.

What Conditions Cause Thunderstorms

Thunderstorm occurs as a result of cumulonious cloud(s).
A thunderstorm goes through three distinct stages- Cumulus stage, Mature stage and Dissipating stage.
The cummulus stage is the growing phase when the cloud is still growing phase when the cloud is still growing and contains abundance of rain drops with icy crystals or supercooled drops in the upper levels of cloud maintained there by the updrafts.
The mature stage is reached when down drafts have also commenced within the cloud and coexist there with the updrafts consequently these start falling as rain.
The dissipating stage is reached when rain or hail or both.
have precipated out.

Thunder is the sound of the shockwave caused when lightning instantly heats the air around it to up to 30 000 °C (54 000 °F). The exact mechanism is poorly understood.
