...Since when does rain transform into lightning? It turns into snow or hail lol.

Lightning is made from hot and cold air. The warm air rises and carries water droplets, which rubs against the ice crystals in the cold air and creates static electricity. When the negative charge on the bottom of the cloud gets high enough, it releases the lightning bolt which can either strike the ground or run along the clouds.
