Extensive line of thunderstorms brings broad swaths of damaging winds, along with a few tornadoes, to portions of south central Nebraska during the late evening hours of May 23rd into the early morning hours of May 24th. A cold front associated with a closed upper low pressure over the Dakotas sparked a line of thunderstorms to develop during the late afternoon hours from central SD into the NE Panhandle. This activity, fueled by strong instability (MLCAPE 1500-3000 J/kg) and deep layer shear, become intense and organized prior to moving into far W portions of the GID CWA around 10pm CDT. The line continued to strengthen and organize as it shifted eastward into deeper low level moisture and, in turn, began to produce occasional QLCS tornadoes. The line impacted the Tri-Cities shortly after midnight. Of the Tri-Cities, Hastings was by far the most severely impacted, with several reports of wind gusts around 60 MPH and extensive tree damage in and around town. An 85 MPH wind gust was measured just west of Hastings in the Heartwell area. As storms continued eastward during the early morning hours of the 24th, damaging wind remained the primary threat. The strongest and most concentrated area of wind reports occurred roughly along the Highway 74 corridor in Clay and Fillmore Counties. Here, a 75 MPH gust was measured by a mesonet just E of Edgar. The severe portion of the line exited eastern portions of the forecast area by 2AM on the 24th. In total, there were 5 confirmed tornadoes from this event, all of which were of the weak and QLCS variety. The most impactful tornado, and the only one to hit a population center, was in Holdrege, but even this damage was fairly minor and rated as an EF1.

An EF1 tornado tracked catty-corner from southwest to northeast across Holdrege. Much of the damage was noted in trees throughout town. Some large trees were uprooted or snapped. A handful of garages sustained damage. The tornado winds initially damaged the garage door, after which some structural wall damage occurred. The peak wind speed was estimated to be 95 MPH, based on the damage to both trees and structures along its nearly two mile path.

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 00:59 UTC.

26 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.
