What happened

The episode as NWS PAH wrote it up.

Two organized storm systems moved out of the southern Plains on the 5th and 6th and the 8th and 9th. Total rainfall from these two storms averaged between 1 and 2 inches. Although not excessive, this was enough rainfall to cause minor flooding of the Ohio River at most points on the Illinois shore. At Shawneetown, where flood stage is 33 feet, the crest of 36.5 feet occurred on March 12. Crests at Brookport, Grand Chain, and Cairo were all less than a foot and a half above flood stage. Some agricultural lowland was flooded.
