A monstrous supercell is born in McCook, Neb., on June 19

Storm-chasing photographer Mike Hollingshead makes a living diving into dangerous situations to document the raging turmoil of a thoroughly pissed-off atmosphere. This footage of a supercell thunderstorm forming in McCook, Neb., represents some of the finest work in Hollingshead's "Extreme Instability" portfolio, which you can see more of here.

Two massive clouds prepare to collide

A shelf cloud in the bottom right is about to crash into the supercell in the center. Mike: "You think to yourself, noooooooooooooo, a messy big line and shelf is about to ensue. This would seriously be the case 99 times out of 100 when two big supercells merge, especially when one already has a big ol bowing shelf with it."
