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.

Nobody in McCook is sleeping, now

The roll clouds were really hauling butt, Mike says. "The above shutter was 3 seconds for instance." Time: Right around midnight.
