The featured graph is a time series of one minute interval precipitation rates and totals from the Lamoni SchoolNet station on Saturday morning. The red line shows an accumulated total of over 5 inches before noon with over two of those inches falling within an hour between midnight and 1 AM. The other two lines represent hourly accumulation rates based on two different time windows. On a 15 minute interval, rainfall rates exceeded 4 inches per hour, which is an extreme rate for Iowa. These rates were possible thanks to a saturated atmosphere with warm cloud temperatures.
