Aug 18, 2014
An upper level low pressure system tracked southeastward from the St. Louis area through the Mid-South on August 17th-18th, 2014. The upper level low interacted with daytime heating to produce showers and thunderstorms across the area during the afternoon and evening hours on both days. Some storms became severe producing large hail and flash flooding. The storms diminished after sunset due to the loss of daytime heating.
