Episode narrative: The most notable storm of the day was an intense, long-lived, cyclic tornadic supercell which significantly impacted Scotts Bluff and Morrill Counties during the early evening hours. This storm originated in the central Laramie Range of Wyoming approximately 50 miles to the west around 3 to 4 hours prior to reaching western Nebraska, producing several confirmed tornadoes along its path. Environmental conditions across Scotts Bluff County continued to support the potential for tornadoes, with abundant moisture pooling in the Platte River Valley and favorable east-to-southeast winds near the surface with a strong southwesterly jet stream aloft. The supercell produced 7 additional confirmed tornadoes (6 in Scotts Bluff County and 1 in Morrill County), most notably including an EF-2 tornado which tracked approximately 1-3 miles ENE of Gering between 7:38 PM and 7:45 PM MDT. A Tornado Emergency was in effect for Gering and Scottsbluff from 7:31 PM until 8:00 PM MDT, which was the first ever issuance of this product from the NWS in Cheyenne. Numerous instances of baseball to softball sized hail occurred across Scotts Bluff County including the city of Scottsbluff. A second intense supercell developed and tracked across Scotts Bluff County in the wake of the first tornadic storm, producing a second swath of very large (baseball sized) hail over the same area. In addition to this primary focus area for intense storms, other isolated storms also brought quarter sized hail, 60 MPH wind gusts to portions of the western Nebraska Panhandle.

Episode narrative: An intense, long-lived supercell initially developed near the town of Chugwater over the higher terrain of the central Laramie Range around 3:00 PM on 6/23, tracking to the east-southeast across southern Platte and Goshen Counties through approximately 7:00 PM. A small, terrain-driven area of low pressure and resultant cyclonic flow resulted in moisture pooling and backed, easterly near-surface flow near the track of the storm which resulted in a favorable environment for tornadoes. The cyclic supercell produced 5 separate confirmed tornadoes, most notably including an EF-2 tornado which developed near the town of Hawk Springs. A swath of large hail up to two inches in diameter also occurred with this storm. A separate storm over far northwestern Converse County also produced a brief tornado that afternoon. A second round of strong to severe thunderstorms impacted Platte and Goshen Counties later in the day.

Event narrative: A large cone tornado developed just east of US-85 south of Hawk Springs, before quickly becoming rain-wrapped. The tornado snapped cottonwood trees, with a tree branch impaling a stucco house. It also damaged outbuildings and snapped power poles. An injury occurred when the tornado flipped an 18-wheeler and injured the driver. The same tornado tracked to the southeast and damaged another outbuilding and a barn 3 miles southeast of Hawk Springs. The tornado was officially rated an EF-2. In addition to the tornado damage, straight-line winds from the Rear Flank Downdraft (RFD) damaged several hardwood trees. This is consistent with 100 MPH winds.
Episode narrative: An outflow boundary from earlier day convection focused a gradient of instability and storm development with additional destabilization from heating by early afternoon. Boundary interactions from sluggish storms led to training of heavy rainfall cores, as well as a couple brief tornadoes. Extensive flooding resulted in a state disaster declaration for Sioux County.
