Thunderstorms erupted during the evening in south-central Nebraska. One storm near Aurora produced very large hail. One stone measured by an NWS Storm Survey team was determined to be the largest sized stone to fall in the United States. It measured 7 inches in diameter and 18.75 inches in circumference. Many other large stones were noted on the northern side of Aurora. Given the lack of wind, damage was limited to roofs, a few windows and some crop land near town. The storm also produced a couple of brief small tornadoes as it slowly moved through northern Hamilton county.At nearly the same time, another very slow moving storm produced several tornadoes, hail and extremely heavy rains in Thayer county. One tornado moved through the town of Deshler going from the southeast side of town to the west. One man was killed in his garage before he was able to get to shelter. Over 400 homes in Deshler were damaged with four being completely demolished. Nearly 100 homes were moderately to severely damaged. Six businesses in town were considered a complete loss and 25 others reportedly suffered moderate to severe damage. Seven people were injured, most were minor and were from broken glass. Later in the evening, a tornado was reported north of Bradshaw in York county. Storm spotters about 1 mile west of the tornado saw debris being flung through the air. A farmstead was hit with most of the damage done to an old barn.Despite ongoing drought conditions, widespread flooding was reported in Thayer and southern Fillmore counties. The flash flood along the Rose Creek at Hubbell provided some of the worst damage. Water was flowing into houses and businesses on main street to the tune of up to 5 feet deep. Boats were the only mode of travel through the business district. Up to 15 residents had to be evacuated by the local Dive and Rescue team using jet skis. The flooding was caused by extremely heavy rainfall in nearby Republic County, Kansas.Flooding and flash flooding was also a problem throughout Thayer county. Rainfall of over 12 inches was reported about 5 miles north of Deshler. Residents reported nearly 5 hours of constant, wind-driven rain. Windows were blown out and the rain just poured into homes. Widespread agricultural damage was done due to the rain. The runoff in the Snake and Spring creeks ravaged Deshler, the town which had already been hammered by tornadoes that evening. Flooding was concentrated in the southern part of town and most widespread near the park and fairgrounds.Major river flooding was reported along the Little Blue River from just west of Hebron to the Jefferson county line. One man at his farmstead near Gilead had to be air lifted to safety by the National Guard as flooding waters rose on his property. Dozens of county roads and bridges were damaged or destroyed. U. S. Highway 81 was restricted to one lane travel at Hebron due to the high water on the road. Portions of Highways 81, 136 and 9 were closed for a time due to high water. The Big Sandy Creek flowed out of its banks at Alexandria and crested at 14.5 feet. Water was flowing over the highway near town and filling back into the town's sewer drains. In all, several million dollars in damage was done by the flooding alone. Some locals said this was the worst flooding in the area in 55 years.

The last of four tornadoes to occur near Deshler. Damage was primarily to crops and pivot systems.

39 minutes of warning. NWS GID issued a tornado warning for this county at 23:21 UTC, 39 minutes before the tornado touched down, in force until 00:00 UTC.

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 Moderate Risk, with a 0.15 chance of a tornado within 25 miles. The outlook in force was issued at 19:45 UTC.

14 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.
