Thunderstorms developed in a southwest to northeast line along a cold front that pushed across eastern Nebraska and western Iowa during the late afternoon and evening of July 14th.  Ahead of the front temperatures climbed into the mid 90s with dew point temperatures in the mid 70s to around 80.  This created a very unstable environment for the storms.  As the storms encountered the extremely unstable conditions they increased in strength, and besides producing very heavy rain, wet micro-bursts developed with some of the storms.
