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.

Effects

 * Thunderstorms are much darker than normal rain, at light level 7 or less.This is dark enough to spawn enemy mobs.
 * Lightning creates the fire effect mobs have when they burn, but it doesn't create real fire.
 * If Lightning strikes a pig, it morphes into a zombie pigman.
 * If lightning strikes a creeper, it becomes electrified and has a much more powerful explosion.
 * Being struck by lightning or standing near a lightning strike deals 5 hearts of damage, not including damage from the fire.
