An overview of the conditions that lead to the flash flooding that occurred over southwest Nebraska on 6 July 2002 was presented. It was found that deep and persistent moisture advection, weak upper level flow and the existence of a low level trough combined to produce heavy precipitation over several hours. This feature remained nearly stationary for several hours and served as the focal point for the continual upward motion and development of deep moisture convection as storms moved into the OGA region. The development of a process to examine and compare an ensemble of ETA and MM5 forecasts to assess their respective change in predictability over time for this event was also discussed.
