After the lightning strike, the fireball that spawned from it still lingers. These are very deadly and have been known to burn through cars and house wall, and kills any victim it comes in contact with...A good percent of them will linger for 5 or 20 seconds or so then explode with a good amount of force to them.

This particular one will drift 6 feet above the ground, and once well past the railroad tracks it will explode with a very loud boom.

The glowing yellow spot on the road is where it is still hot from where lightning struck the pavement.
