The Coal City-Braidwood tornado developed near Higgins Road and Dupont Road in Grundy County about 1 mile south of Diamond.  It moved to the ESE snapping trees and power poles along N. Gorman Road.  As the tornado entered the village of Coal City, dozens of homes were heavily damaged.  Three were completely destroyed.  Per the NWS Summary, “Two of these homes were well built and had at least part of their structure bolted down to the foundation with bolts secured by nuts.” 

Two high tension metal trusses were brought down and one of them was “crumpled” along Hunters Run.  Hundreds of trees were snapped or uprooted and numerous utility poles were downed. 

As the tornado moved into Will County, it weakened.  Tree damage was produced across part of the property of the Braidwood Nuclear Generating Station.  Wooden power poles were snapped along Route 53 and also along Zilm Road.  A garage was heavily damaged along Ohlues Road.  The tornado dissipated 2 miles SSE of Ritchie.
