An intense cluster of thunderstorms rolled through Iowa on Saturday bringing much needed rainfall to lucky portions of the state. The rainfall was quite intense for some as shown by the featured graph of one minute interval rainfall from the Davenport Airport site. 2.38 inches of rainfall was reported between 1:37 and 2:03 PM on Saturday. The black line shows the one minute intensities extrapolated to an hourly rate. The green line is the same extrapolation, but over a 15 minute trailing window. Unfortunately, intense rains like this probably included significant run-off instead of soaking into the ground. The water did not disappear though so rivers and lakes benefited from this event as well.
