| Brief Description: EVENT NARRATIVE: At 930 PM CDT, a tornado touched down approximately 12 miles northwest of Springview and traveled northeast for 20 minutes before lifting 11 miles north of Springview. The tornado did extensive tree damage when it touched down, then moved northeast and struck two farmsteads. At the first farmstead, a loafing shed and stock trailer were destroyed, extensive tree and fence damage occurred, and a roof was torn off an old hog building. The most extensive damage occurred north of the farmstead where six rural electric association poles where broken. The tornado continued to move northeast and destroy a windmill. Then a second farmstead was hit with the tornado destroying a 40 by 60 feet quonset building before the tornado lifted at 950 PM CDT. EPISODE NARRATIVE: Thunderstorms developed along a semi-stationary front that stretched north to south across the Central Plains. By late evening, the front extended south near Highway 83 in northeast Cherry County. The storms rapidly intensified moving northeastward and produced large hail up to 1.25 inches and two tornadoes. | |||||||||||
