...Summary...
With assistance and coordination from the Boone County Emergency Management
Agency, the National Weather Service completed a survey along I-275 in Boone
County today. The survey focused on barn and tree damage on both sides of
interstate.

Damage begins with minor roof damage to a home and accompanying tree damage
on Stevens Road in northern Boone County northwest of Idlewild.  About a mile
downstream, the likely tornado struck a barn with heavy damage to the
structure. Wall collapse and complete roof removal was noted.  Numerous
trees were also uprooted in vicinity of the barn. Roofing material was lifted
and deposited a considerable distance downstream, with roofing material lying
along I-275 almost a half of a mile downstream of the barn.  The tornado
continued east along I-275 causing sporadic but minor tree damage. Another
barn was damaged with partial roof removal on the south side of I-275.  Some of
this material was carried across I-275 and deposited about a half mile downstream
on a nearby golf course.  The tornado appears to have lifted in the vicinity
of I-275 about a mile west of Exit 8.

There are some gaps in the damage path indicating a complete and constant
contact with the ground did not occur with this weak tornado. The
vast majority of the tree damage indicates wind speeds between 60 and 75 mph,
though indications of wind speeds around 90 mph /EF-1/ are present with the heavily
damaged barn on the south side of I-275.

The National Weather Service would like to thank the Boone County Emergency
Agency for considerable assistance with this survey.
