Repetitive showers and thunderstorms, moved southeast through western Vinton County, Jackson County, and western and central portions of Lawrence County between 1500E and 1830E on Tuesday, the 10th.  This convection was just northeast of the surface warm front.  A sharp dew point gradient existed along the front.  Surface dew points were around 70 degrees just southwest of the boundary.  Luckily, later that same evening, repetitive convection occurred in the Scioto River Valley, missing this area just to the west.
Initially, the main impact was large hail.  As back building caused repetitive showers and thunderstorms, flooding became the primary issue.  Maximum rain amounts of 3 to 4 inches were observed.  Jackson measured 3.35 inches.  Waterloo observed 3.76 inches.  South Point had 3.25 inches of rain.
Luckily, no injuries or fatalities occurred.
