Although the brunt of severe thunderstorm activity focused just to the south across Northern Kansas, two separate rounds of isolated severe weather affected parts of South Central Nebraska. The first round of severe storms moved in around sunrise on Saturday morning, passing through areas mainly south of Interstate 80 and west of Highway 281. This MCS first organized across Northeast Colorado and Southwest Nebraska shortly after midnight, before rolling east-southeast into the area. These storms were slightly elevated, focusing along the nose of a low level jet, and to the north of a nearly stationary, east-west surface front draped across Central Kansas. The synoptic environment featured considerable instability, with MUCAPE values of 1000-3000 J/kg, and deep-layer wind shear of 30-40 knots. These storms produced hail up to quarter size, and also damaging winds, mainly across Furnas, Harlan and Phelps Counties. Near Funk, estimated 80 mph winds downed approximately 60 power poles.
Once these morning storms moved out, the remainder of the daytime and evening hours were quiet. Then, starting around midnight and lasting into the pre-dawn hours on Sunday, additional strong to severe storms flared up along the nose of a strong 40-50 knot low level jet, riding over a warm front that had moved north to near the Nebraska-Kansas border. In the presence of around 2000 J//kg of MUCAPE and deep-layer shear around 40 knots, a few of these storms produced hail up to quarter size across several counties near the Highway 281 corridor.
