What happened

The episode as NWS DMX wrote it up.

The same storm system that produced severe weather in the morning advanced east during the day. Though no severe weather occurred during the evening, moisture had increased significantly by the evening hours as dew point temperatures reached 60 degrees just south of Iowa. This moist air was lifted along a weak cold front advancing across the state and thunderstorms developed over parts of central and southeast Iowa. Rainfall was heavy for late February. One to two inches of rain fell in under two hours over the south third of Jasper County. This caused urban flooding as the soil was quite moist from recent snow melt. The flooding was not a major problem, but considerable ponding was reported on roadways.
