A cluster of low level jet initiated storms in central Nebraska slowly made their way eastward overnight and during the early morning hours of the 14th. With zonal flow aloft, their general motion was directly eastward. As the low level jet waned in the morning, the overall extent of the storms diminished, but never fully ceased. As diurnal heating increased the storms remained on the leading edge of the gradient, where MUCAPE values crept into the 1000-3000 J/kg neighborhood. While hail cape values were marginal, under 800 J/kg, there was enough effective bulk shear, around 40 to 50 kts at times, to allow storms to organize and produce periods of heavy rainfall and severe hail. The majority of storms produced marginally severe hail, with a couple of reports as large as ping pong balls.
