Detailed Event Summary:
On the late afternoon and evening of Memorial Day 2013, an upper level disturbance shifting out of the Rocky Mountains and onto the Central Plains brought yet another round of severe thunderstorms to South Central Nebraska and North Central Kansas.  Through the afternoon hours, increased dewpoints allowed for high amounts of instability, while wind shear was also picking up across the area.  A surface warm frontal boundary would provide an extra focus, and thunderstorms which developed quickly became severe.  Very large hail and damaging winds were reported along with heavy rain, but the main story was with the confirmed tornadoes. 
 



Some of the notable reports from Monday afternoon and evening follow below:

  • Tornadoes reported in Smith/Jewell Counties of North Central Kansas and in Clay County of South Central Nebraska (see below for more detailed information regarding these tornadoes)
