What happened

The episode as NWS GID wrote it up.

Severe thunderstorms pounded portions of south-central Nebraska with heavy rain and hail during the evening hours. An average of 4 to 6 inches of rain fell across southern York county forcing water over U.S. Highway 81 in McCool Junction. Widespread hail and wind along with the heavy rain caused substantial corn and soybean damage. Some county roads and bridges near Henderson, Bradshaw and McCool Junction were damaged by the high water. A storm chaser in the area witnessed a brief tornado south of York. It touched down in an open field and caused no damage.
