Episode Narrative A strong weather system moved through the central U.S. from the 21st through the 23rd of the month. Strong convection formed north of a warm frontal boundary lifting north through the state. A cold front dropped southeast, producing severe weather on the 21st before it stalled out to the south of the state. As it lifted northward, deep moisture was transported into the upper Midwest as the remnants of a former eastern Pacific Hurricane was drawn north. The tropical moisture resulted in heavy rainfall over a large part of Iowa again on the 23rd, with some places in southern Minnesota receiving 6 to 10 inches of rain. The rainfall from Minnesota flowed down the Des Moines River and produced flooding as far south as Humboldt. The heavy rain that fell over Iowa during this event caused flooding farther south on the mainstem Des Moines, and on the South Fork Chariton River. The flooding caused some property damage and minor crop damage. Since much of the summer saw very elevated river levels, the flooding caused less damage than would be otherwise expected.
