...Summary...
The National Weather Service in Wilmington OH has confirmed a
tornado southwest of Enon in Clark County Ohio on April 5, 2017.

The first evidence of damage occurred to a home and farm 
buildings along Dayton-Springfield Road southwest of Enon. 

While there were numerous homes in the area which sustained tree 
damage and lightweight debris damage, the vast majority of this 
damage was from straightline winds estimated at 70 mph. The wind 
damage was southwest to northeast with no evidence of tornadic 
winds making direct contact with the ground nor debris found on 
downwind sides of buildings.

There was embedded damage to a farm home and barns where large
sections of roofing material was peeled off and lofted, causing
damage to the downwind home. There was additional roof damage to
the home and 2 additional farm buildings. The southward facing
garage door to the home was blown inward. Two combines located in
one of the outbuildings were pushed downwind, with the outbuilding
itself collapsed. 

Where there was evidence of tornado damage was in the 
downwind/northeast facing wall of the home and one of the barns, 
where debris splatter was observed. Because of heavy rain after 
the passage of the storm, direct ground damage indicative of a 
tornado in contact with the ground was inconclusive. 

For reference: the Enhanced Fujita Scale classifies tornadoes
into the following categories:

EF0...wind speeds 65 to 85 mph.
EF1...wind speeds 86 to 110 mph.
EF2...wind speeds 111 to 135 mph.
EF3...wind speeds 136 to 165 mph.
EF4...wind speeds 166 to 200 mph.
EF5...wind speeds greater than 200 mph.

...TORNADO CONFIRMED NEAR 6 MILES WEST OF SPRINGFIELD IN CLARK

...Summary...
The National Weather Service in Wilmington OH has confirmed a
tornado 6 Miles West of Springfield in Clark County Ohio on April
5, 2017.

Widespread wind damage was observed west of Springfield in the
Tecumseh Trails Subdivision and along North Tecumseh Road north
of New Carlisle Pike. Several homes in the Tecumseh Trails
subdivision sustained roof damage indicative of 75 to 80 mph 
winds. However, all of the debris was scattered in a northerly to 
northeasterly direction, with no ground based evidence of a 
tornado apparent. There was no evidence of light mud nor debris 
splatter in the downwind facing side of the homes. However, the 
wind damage was significant, resulting in a large section of roof 
removed from one home, with other homes in the area sustaining 
smaller sections of roof damage. There was additional tree damage
along New Carlisle Pike, including damage to a fence caused by 
damaged trees. 

Where tornado damage was evident was further east along North 
Tecumseh Road. Roof and siding damage was sustained by several 
homes. One home had clear debris splatter on the north facing side
of the home, as well as splatter and damage on an eastward facing
porch. This strongly suggests winds traveling in an opposite 
direction of the north to northeastward moving storm and provides 
evidence of tornadic damage. 

The storm traveling through this area of Clark County had
significant winds producing widespread tree and roof damage.
Nearly all of the damage surveyed was pretty clearly in a
northerly to northeasterly direction, indicating strong straight
line wind damage. Damage caused by the brief tornado touchdown 
along North Tecumseh Road was similar in magnitude to the 
strongest straight line wind damage nearby. 

Through witness accounts, it is estimated that the tornado was on
the ground a very brief time, likely less than 1 minute. 

For reference: the Enhanced Fujita Scale classifies tornadoes
into the following categories:

EF0...wind speeds 65 to 85 mph.
EF1...wind speeds 86 to 110 mph.
EF2...wind speeds 111 to 135 mph.
EF3...wind speeds 136 to 165 mph.
EF4...wind speeds 166 to 200 mph.
EF5...wind speeds greater than 200 mph.
