Top Summer Hourly Precip

Posted: 02 Aug 2024 05:30 AM

Our recent and numerous rounds of thunderstorms have featured a number of heavy precipitation events. Such is the case this time of year when the lower atmosphere is the warmest and most loaded with water vapor. The featured chart presents the largest hourly precipitation totals for Des Moines during the summer months, based on near top of the hour reports. A total of 1.95 inches early Wednesday morning comes in 6th highest for the site. A major caveat with this type of analysis is that it is based on once per hour reports, so it does not truly capture the largest peak precipitation rates over any 60 minute period.
