Read the full account →A line of heavy thunderstorms developed over west central into northwest Iowa. Though no severe weather was reported, heavy rainfall occurred. The thunderstorms "trained" over the same areas for several hours, dropping up to 3 inches of rain per hour at times.
Read the full account →The month of June had to give Iowa one last gasp of heavy rainfall. Since the soil was already saturated, it did not take much rainfall to cause renewed flooding. Moderate rains of 1 to 2 inches occurred on the 27th through the 29th.
Read the full account →A complex weather situation was set up over the central U.S. as a mesoscale convective system passed to the south of Iowa during the overnight hours and early morning of the 29th. Initially, the surface warm front was located to the south of this system.
