Storms of 2012 - Jeff Frame
Missouri Valley HP Supercell

Missouri Valley HP Supercell

After chasing NW North Dakota the previous day, we somehow made it to the Missouri Valley of eastern Nebraska on May 23, 2012. We observed multicellular convection organize into an HP supercell just prior to crossing the river into Iowa (where chasers' dreams go to die). The storm then appropriately accelerated to 55 mph and we abandoned it soon after. Looks north from north of Blair, Nebraska.
