It had been over a month since significant rainfall fell on Ames and Des Moines. Big and slow moving storms brought severe weather and heavy rainfall to the area. The featured chart presents the largest "hourly" precipitation totals reported by the Ames Airport weather station. The "hourly" totals are shown for the station's mandatory hourly reporting time at 53 minutes after the hour. It is one of the reporting quirks that makes working with the dataset so much fun. Anyway, the event yesterday ranks third with data dating back to 1996.
