Bomb cyclone

Ice forms on a calf at a ranch outside of Kilgore, Neb., Wednesday, April 10, 2019. A bomb cyclone storm bringing heavy snow and strong winds to several Rockies and Plains states is making travel difficult in many areas and impossible in others. Officials have closed Interstate 29 in northeastern South Dakota and say other stretches of interstates are likely to close later. (Chris Machian/Omaha World-Herald via AP)
