|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.|
