Past IEM Features tagged: rainfall
Storms this past weekend brought damaging winds, hail, heavy rainfall and even tornadoes to Iowa. The weather sensor at the Des Moines Airport reported its second largest daily rainfall for the month of April. The featured chart presents the one minute interval rainfall observations from the site. These values are extrapolated to rates over an hour period showing peak intensities over 12 inches per hour! Of course, these most intense rates do not last that long with actual hour accumulations reaching just over 2 inches per hour (red line).
