Straight-line winds of 80 to 100 mph destroyed a pole barn about 1 mile southwest of Protivin (Howard County), blowing debris from the barn about 3/4 of a mile into an open field.  A nearby farmer's mill sustained minor damage as well.  Several buildings in a lumber yard on the south side of Waukon (Allamakee County) had roof damage, with sections of roof thrown downwind to the southeast.  Some sheds and supplies in the lumber yard were also shifted to the east or southeast.  Along Highway 76, just southeast of Waukon, a small tornado hit a farm, damaging part of the house and at least one outbuilding.  A nearby church was damaged by the same tornado.  In fact, a family who had taken shelter inside the church reported a stain glass window was completely gone following the storm, with no evidence of broken glass found anywhere near the building.  Storm chasers also reported a brief tornado touchdown in open fields between Ionia and New Hampton (Chickasaw County), but no damage was reported.  In addition, hail ranging in size from dimes to quarters was reported by storm spotters and amateur radio operators.
