On the evening of July 27th, a frontal boundary stalled along the Highway 20 corridor, spawning a series of thunderstorms that inundated the tri-states with record rainfall. Here at the library, we watched the streets outside the library flood briefly and momentarily lost power. Lightening struck and damaged the Bishop's Block Building downtown, but the library escaped with little damage, especially compared to many others in Dubuque, East Dubuque and the surrounding area.
While we're no strangers to flash floods and extreme weather here, the July 27-28 event broke six rainfall records for Dubuque, including the most rainfall ever recorded in a 24-hour period (10.62 inches; previous record of 8.96 in 2002), most rainfall recorded in July (16.01 inches; previous record of 12.68 in 2010) and most rainfall recorded in a single month (16.01 inches, previous record of 15.46 inches in 1965). It also caused the Mississippi River to rise four feet in 12 hours, caused an estimated $2 million in damage, left many homeless and resulted in one fatality.
