During the late afternoon hours, a nearly stationary, east-to-west surface boundary was anchored near the Nebraska and Kansas state line. With a large mid-level trough poised to the west across the Central Rockies, the environment was at least somewhat supportive of isolated severe weather given impressive deep-layer shear values around 60 knots, and SBCAPE increasing to around 1000 J/kg. A cluster of thunderstorms initially developed across Northwest Kansas near the intersection of the surface boundary and a weak low, with some of these storms then spreading northeast into Furnas County. As one of these storms encountered the east-west surface front in the presence of 0-1 km storm-relative helicity around 150 m2/s2, it produced a short-track EF1 tornado southeast of Beaver City.
Although no other storms became severe across South Central Nebraska during the evening, locally heavy rainfall upon already-saturated ground resulted in several instances of flash flooding and subsequent road closures. One of the most noteworthy flash flooding events affected northern Greeley County along the Cedar River. As a result of several rounds of heavy rainfall during the past few days, an upstream dam break occurred on the Ericson Dam in Wheeler County, causing water to drain from the lake into the Cedar River.  Flooding along the river commenced, and by nightfall Sunday evening, six inches of water was flowing over the Highway 281 bridge near the Greeley-Wheeler County line.   Flooding continued downstream along the river to Spalding, and Spalding Lake reached its capacity on Monday, June 14th, with water occasionally overtopping Spalding Dam. Several county roads or bridges were washed out in the Spalding area.

Most of the tornadic path crossed over rural areas, with the main damage noted to trees.  However, one farmstead was struck and received significant damage.  Several metal buildings of various sizes sustained major damage or were destroyed.  Three round grain bins were blown away.  A large propane tank was blown approximately 40 yards to the northeast, and a four wheeler ended up 100 yards from its original position.  A semi trailer was moved, while several farm implements suffered damage.  Quite a bit of tin from the buildings was noted downwind, with some of it being lofted into the trees of a shelter belt, about a half mile east northeast of the farmstead.  The house had broken windows and some siding was torn off.  Significant tree damage was also evident at the farm.
