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.

A tornado occurred in open country west of Gering with no damage reported. Confirmed by official NWS Storm Survey.

A tornado tracked approximately 1 to 3 miles ENE of Gering, causing significant damage to a structure with debris scattered up to 1/2 mile to the west, including hazardous material. Vehicles on the property were thrown 50 feet. A small wooden trailer was thrown 1/4 mile away. Additionally, irrigation pivots were rolled numerous times and power lines were broken along Highway 26. Damage was consistent with an EF-2 tornado. Confirmed by official NWS Storm Survey.

A confirmed tornado produced a broad, diffuse area of damage along CR 24 and Highway 92 from a secondary tornadic circulation just east of the main Gering tornado. An EF-1 rating was based on a quonset collapse and broken power poles.

A trained spotter reported a rain-wrapped tornado with lofted debris near the intersection of CR 26 and Highway 92.

A trained spotter reported a tornado 2 miles WNW of Minatare.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Enhanced Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 01:05 UTC.

23 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
