July 24th 2008 Supercell Thunderstorm
On July 24th 2008, severe thunderstorms developed across north central Nebraska in response to a weak shortwave tracking through the region. Strong instability coupled with modest deep layer shear created an environment capable of sustaining organized thunderstorms, including supercells. The storms tracked southeast producing sporadic reports of wind damage and hail. Refer to the link below to see the actual reports:

One particular storm of interest developed supercellullar characteristics as it moved southeast through Thomas and Logan counties, and eventually nearly due south into Lincoln county as stronger instability built westward. The storm developed low-level rotation and a tornado warning was issued as it continued south southeast through Lincoln county. Classic signatures of the storm's rotating updraft were observed on radar and by eye as the storm slowly moved south through Lincoln county. Very large hail, with some hailstones greater than 2.00 inches, was observed in Lincoln county when the storm was at its peak intensity along with several rotating wall clouds. Taylor Trogdon, a student volunteer at the National Weather Service in North Platte, observed the storms with the following images taken and provided below.
