An afternoon thunderstorm with winds of up to 70 mph knocked down trees and caused scattered damage to buildings in the tri-state area on Tuesday. In downtown Manchester, Iowa, the storm took some roofs off of commercial buildings in Manchester and flattened a pole barn northwest of the city. Hail of up to 1.75 inches — the size of golf balls — also was reported by first responders. The storm also downed a tree across a powerline on North Franklin Street in Manchester, and traffic was being detoured for a short time. In Dubuque County, wind gusts of 70 mph were reported near Dyersville and of 60 mph at Dubuque Regional Airport. Both locations reported quarter-sized hail. A tornado warning was issued for Dubuque County late Tuesday afternoon, but there was no indication of a tornado touchdown.
