What happened

The episode as NWS PAH wrote it up.

Heavy rainfall during the first half of April sent the Mississippi River above flood stage. Rainfall amounts during the first six days of the month ranged from one and one-half to over 4 inches. At Cape Girardeau, where flood stage is 32 feet, the river crested at 35.6 feet on the 22nd. This resulted in minor flooding of primarily agricultural areas. The Mississippi remained below flood stage at New Madrid.
