Overview

The warm front that was responsible for the significant tornadoes on the afternoon of the 16th, lifted slightly north on the 17th into far northeast Nebraska. Extreme instability again developed along this boundary given the very warm and humid airmass in place across the region. By late afternoon an isolated supercell thunderstorm developed along this boundary and quickly become severe. This lone supercell produced several tornadoes, three of which were strong, as well as large hail and flash flooding, over Cedar County Nebraska over the next 4 hours. These storms were unique in that they were nearly stationary for a couple of hours, this resulted in short and meandering paths despite fairly long tornado life cycles.
