Survey Summary:

A 2.5 mile wide swath of damaging thunderstorm winds extended for
approximately 20 miles from near Glasgow, across northern Metcalfe
County, to about 7 miles southwest of Greensburg. Most of the damage
was to barns - ranging from loss of roof panels to complete
destruction.  Much of the damage was obviously caused by straight-
line winds of 75-90 mph, but there were pockets of narrow damage
paths with winds between 100-110 mph that exhibited evidence of
rotation. One area where this occurred was about 1/2 mile north of
Center, in northern Metcalfe County, where a large well-built barn
was destroyed, with the debris lofted over nearby buildings, and
spread cyclonically for up to 1/4 mile to the east-northeast.  A
county and a regional emergency manager witnessed rotation in the
clouds as this barn was destroyed, confirming at least a brief
touchdown of an EF-1 intensity tornado with peak winds of 110
mph.  A Civil Air Patrol is scheduled to fly over the path on Friday
to help determine if any of the other peak wind areas may have
exhibited less obvious rotation.

In addition to the wind damage, there was considerable home damage
caused by large, wind driven hail, especially in northern Metcalfe
and Green counties, where countless homes sustained holes in vinyl
siding, some to the point of shredding.

EF Scale:  The Enhanced Fujita Scale classifies tornadoes into the
following categories:

EF0...Weak.....65 to 85 MPH
EF1...Weak.....86 to 110 MPH
EF2...Strong...111 to 135 MPH
EF3...Strong...136 to 165 MPH
EF4...Violent..166 to 200 MPH
EF5...Violent..>200 MPH
