The area between Ames and Des Moines has had quite the July for heavy rainfall events. After an event on 2-3 July brought upwards of ten inches just northeast of Des Moines, another deluge of rain fell Monday evening (20 July) with roughly the same area targeted with the highest amounts. The featured map presents the combination of MRMS 24 hour precipitation estimates ending Tuesday morning with available NWS Local Storm Reports, COOP observations, and CoCoRaHS reports. The map will be updated later on Tuesday after more morning reports are received. While totals with this event were much lower than the one earlier this month, values over four inches are still rather exceptional and even more exceptional to have two such events over the same location during one year.
