| Episode Narrative | For several hours, thunderstorms with heavy rain trained southeast along an axis across western Kentucky into west central Tennessee. The heaviest rainfall and catastrophic flash flooding occurred in west central Tennessee, including Waverly. In western Kentucky, significant flash flooding occurred near the Tennessee border southeast of Murray. The axis of thunderstorms was aligned with a low level axis of convergence in the surface to 850 mb layer. Storms formed along the convergence axis and then propagated toward the southeast. The atmosphere was moderately unstable even during the early morning hours, with mixed-layer capes estimated to be 1000-1500 J/kg just west of the low level convergence axis. Westerly 850 mb winds around 30 knots along the Mississippi River transported this unstable air toward the low level convergence axis. |
| Event Narrative | A rainfall total of 3.47 inches was reported during the overnight storms. Flash flooding was observed in the Reidland area. Culverts were overflowing into yards. |
