The thunderstorm wind damage occurred from 5 miles to the south-

southwest of Andover to the southeast side of Andover. The initial 

wind damage was to a farmstead, which had grain bins dented in and a 

trailer tipped over. Just north of this farm area, a tree row 0.91 

miles in length had extensive tree damage, including snapped 

hardwood tree trunks and large branches, with the damage falling to 

the north and northeast. The wind damage continued to the northeast 

between this location and Andover, but the damage was sporadic and 

largely confined to broken tree branches. In the southeast side 

Andover, there were more hardwood and softwood tree damage, 

including broken branches and two uprooted trees. On the east side 

of Andover, there was damage to several metal building and bleachers 

were flipped over. The metal building damage included pushed in 

metal doors and walls, which led to portions of the metal roofs and 

wood rafter pieces being removed from the structure. All of the 

damage in this area was blown to the north and northeast.
