Two tornadoes occurred along with hail up to the size of golf balls on this Monday afternoon. A few very isolated general thunderstorms developed across south central Nebraska beginning around 1:30 p.m. CST. However, storms did not become severe until after 3 p.m. CST. Severe hail up to the size of golf balls occurred with some storms, which was impressive given the weak shear and pulse-type nature of the storms. A non-supercell tornado occurred near Odessa, in Buffalo County. Somehow, a lone supercell managed to develop over Clay County, and it was responsible for producing a tornado and hail up to 1.5 inches in diameter. Both of these tornadoes were rated EF-0. By 7 p.m. CST, all of the thunderstorm activity had dissipated or moved out of south central Nebraska.
Surface low pressure was quasi-stationary over western Kansas. The warm front extending east from the low lifted into central Nebraska and became stationary. Just prior to most of the thunderstorm development, temperatures were in the lower to middle 70s with dewpoints in the middle to upper 50s. With mid-level lapse rates near 8 degrees C/km, this resulted in MLCAPE of 1500-2000 J/kg. Effective deep layer shear was 15-20 knots, barely supportive of multicell storm mode. In the upper levels, a longwave trough was over the western U.S. with a lead low exiting Nebraska into South Dakota, and a new more potent low dropping into the backside of the trough over the Northern Rockies.
