Texas Mother Ship Cloud

Photo: Rare mother ship cloud formation moves across Texas panhandle
A rare, mother ship cloud formation hovers over Childress, Texas. Tornado-chasers there covered seven hours and 150 miles (241 kilometers) tracking the supercell thunderstorm that produced this cloud formation. Supercell thunderstorms are known to spawn tornadoes with winds exceeding 200 mph (322 kph).
