Extreme Rainfall and Flash Flooding in South Springfield June 15th, 2013

National Weather Service, Springfield, MO

Event Summary

An outflow boundary from a thunderstorm complex which developed along the Missouri / Iowa border during the evening of June 14th pushed south into central Missouri during the overnight and early morning hours of the 15th.  This outflow boundary continued into southern Missouri and interacted with a very moist and unstable air mass during the morning into early afternoon hours of the 15th.  Thunderstorms redeveloped along this boundary and produced very intense rainfall rates along with training of thunderstorms over the same location for a few hours.  The result was a small area of 6 to 9+ inches of rainfall over areas of southern Springfield.  The intense rainfall over a short period of time resulted in flash flooding and several water rescues were required.
