Thunderstorm

A thunderstorm is a weather condition which takes place randomly during some rain- or snowfalls. All changes from these weathers apply, but since lightning occurs and the light level falls below 7, thunderstorms are distinct. This means that during a thunderstorm, aggressive mobs will be able to spawn, even in the brightest of day.

Trivia

 * If you are near lightning when it strikes, you will hear the same sound as that of a TNT explosion.
 * There is a small chance that lightning will set trees on fire. This can happen when lightning strikes really close to a tree and the fire starts under the tree. However, the tree won't burn down completely because of the rain.
 * If lightning strikes a portal it will activate.

Bugs

 * If lightning hits a sheep, it will not get sheered.
