Thunderstorms developed in southeast Nebraska along and south of a weak nearly stationary front during the early evening of Sept 1.  The storms produced a few marginally severe hailstones, but since many of them repeatedly tracked across the same area for several hours, they also produced locally very heavy rain amounts.  The heavy rain caused some flooding and flash flooding east of Lincoln and also helped push the Missouri River back up to near-flood or flood levels in far southeast Nebraska.
