EF3 tornado in Frontier County, Nebraska

The tornado touched down 8 miles northeast of Stockville. It traveled northeast striking a farmstead 10 miles northeast of Stockville. Two buildings were destroyed with extensive damage to multiple structures at this farmstead.

A strong upper level trough of low pressure lifted across the central Rockies during the late afternoon of May 17th. As this feature approached a stalled out frontal boundary, which was anchored along the Kansas and Nebraska border, thunderstorms developed and quickly became severe as they lifted north. A lone supercell produced multiple tornadoes while moving northeast through Frontier County. Two farms sustained damage with the Johnson's farm sustaining damage to every building with the tornado rated an EF-3. As storms moved northeast large hail and damaging winds were reported.
