An upper-level trough was positioned in northern Kansas with a 700 mb temperature gradient stretching into SW Kansas with a wedge of high moisture. On the afternoon of the 27th, supercells initiated and produced severe hail and winds. Into the evening, it became a more multicellular regime with widespread heavy rainfall. This produced flash flooding in multiple counties.
