Low pressure tracking along a nearly stationary frontal boundary draped across central Illinois triggered several rounds of thunderstorms during the late evening of June 26th into the early morning of June 27th. Heavy rainfall on top of saturated ground, and in areas which had been inundated with flash flooding numerous times during the previous several days in west central Illinois, produced renewed flash flooding. In addition, many of the storms produced damaging wind gusts of 60 to 70 mph and hail as large as golf balls.
