The farmer suffered a cracked vertebra and a lacerated hand. In all, five farmsteads were either damaged or destroyed. Several structures were destroyed, including three homes and numerous outbuildings. One modular home was lifted up and dropped 50 feet away from its foundation.

| Brief Description: EVENT NARRATIVE: A large supercell thunderstorm originally spawned two tornadoes with the eastern tornado eventually taking over. The tornado touched down approximately 6 miles south-southwest of Grant and moved northeast for a few miles and then turned northwest to pass 3 miles west of Grant and continue northwest to near the Perkins and Keith County line approximately 12 miles north-northwest of Grant. The tornado encountered the first farm where it destroyed outbuildings and grain bins and damaged the roof of a metal storage building. Damage to the second farm included ripping off half the roof on the home. At the third farmstead, the tornado destroyed grain bins and a barn and ripped a hole in the roof of the home. The tornado also uprooted and snapped off numerous trees, broke off power poles, and overturned center pivot irrigation systems. EPISODE NARRATIVE: An intense upper level low pressure system approached Western Nebraska on March 28th. Supercells developed quickly along a dryline extending from western Cherry County southward through western Chase County. The supercells produced tornadoes, hail, and strong winds during the late afternoon and evening hours. | |||||||||||
