Event narrative

State Road 64 was shut down due to water flowing over the roadway.

Wider weather episode

During the afternoon and evening hours of August 6th, showers and thunderstorms developed across southern Indiana in the presence of sufficient instability. Ample moisture was present across the region, with surface dewpoints in the low-to-mid 70s and precipitable water values approaching 2 inches. The scattered clusters of showers and thunderstorms which developed moved very slowly thanks to weak steering flow and cell propagation was largely driven by cold pool motion and colliding outflow boundaries. One particularly heavy cell was able to sustain itself long enough to produce flash flooding over portions of Floyd County.
