On Tuesday the 19th, a strong east to west front stretched from north central West Virginia on across extreme southern Ohio near the Ohio River.
Rounds of showers and thunderstorms moved into southeast Ohio around 0200E and continued into the late afternoon.  By late afternoon, rain amounts of 1.75 to 2.25 were common, generally from the Route 50 corridor on north through Perry County.   One automatic gauge near New Lexington had 2.31 inches.   Small stream flooding was common in Athens and Perry Counties.  Numerous roads were flooded and closed, but homes were not flooded.  The rain diminished by evening, as the front lifted north.
However, another round of convection followed, well ahead of the cold front.  Severe convection moved up the Ohio River Valley overnight on the 19th into the 20th.  The convection began to weaken as it approached southeast Ohio during the predawn hours on the 20th.  However, due to the fast wind flow aloft, wind damage still occurred in Perry County.  The additional rain was not as heavy, mostly less than a third of an inch.
The total rain event brought a strong rise on the Hocking River through the day on the 20th, reaching flood stage at Athens by late afternoon on the 20th.  The Hocking River crested at Athens during the morning hours of the 21st at 21.17 feet.  Flood stage is 20 feet.  The river fell below flood stage by that evening.   This level kept vulnerable roads near the river flooded.  Yet, no homes were flooded.
