Survey Summary:
The National Weather Service conducted a storm survey for the
macroburst damage received near Richmond in Madison County, 
Kentucky. Damage was first observed along US Highway 25 where some
isolated tree snaps occurred. Plenty of tree damage continued to 
Hunter Lane and extensive property damage occurred to a home where
roof damage and damage to outbuildings occurred. The storm 
continued along Four Mile road where damage to a barn roof 
occurred with more trees uprooted and snapped. Damage continued to
become more sporadic along Greens Crossing Road where lots of 
tree damage and barn outbuildings had roof damage. Richmond 
Speedway also received roof damage to the restrooms and grandstand
seating.

The most concentrated damage occurred along Forest and Kennedy
Lanes where several residents received damage with very extensive
tree damage, including a mixture of uprooted and snapped hardwood
trees. Several barn outbuildings also received considerable roof
damage. Observable damage continued with trees down along Whitt
Road and Speedwell Road and some barn roof damage. Barn
outbuildings and tree damage continued toward Brassfield Road
before the main extensive damage ended. 

A majority of the damage was observed in a southerly direction,
although some damage varied between the easterly and southwesterly
directions. This damage pattern coincides with a macroburst style
severe straight line wind downburst from the parent thunderstorm 
that moved across Madison county. Damage was widespread and 
appeared to even fan out in many areas, which is also consistent 
with a straight line wind event. Most damage was consistently in 
the 90-100 mph range with a max wind speed of 110 in some 
locations. 

The National Weather Service would like to thank the helpful
homeowners that provided access to their property to observe
damage, as well as Madison County Emergency Management for their
assistance in providing damage locations for the survey.
