...Summary...
The National Weather Service in Wilmington OH has confirmed a
tornado near South Vienna in Clark and Madison counties in
Ohio on November 5th 2017.

The tornado first touched down between Ritchie Drive and 
Interstate 70, where a semi-trailer was overturned. Damage then 
was observed approaching Ritchie Dr to Ritchie Brothers 
Auctioneers with a hole in the roof and some siding removed.
The tornado then progressed southeast into South Vienna with 
multiple tree limbs down across E North Street and N East Street 
with some minor structural damage to roofs also occurring. 

Damage then continued towards the southeast along E Main Street.
The tornado then strengthened as it crossed Longs Court and headed
east. Several trees were then snapped around half way up the trees
themselves with at least three trees uprooted towards the eastern
city limits of South Vienna. 

East of where E Main Street merges with E National Road, structural
damage was observed with a garage slightly shifted off of its 
foundation. The tornado then continued southeast with minor tree 
damage observed where Wilson Road and S Houston Pike meet. Damage 
then continued on Markley Road just south of E National Road in 
the form of mostly tree damage. Most trees only had limbs down 
with two being uprooted. 

The tornado then strengthened with structural damage occurring
just south of E National Road on Roberts Mill Road. A trailer
attached to a tractor was then tipped on its side. A barn on the
property then lost the west facing wall with some of the north and
south walls also removed. The east facing wall was completely
removed from the structure. Around 30% of the roof was 
removed with pieces of the barn blown into a corn field towards 
the east. Observed damage from the barn was consistent with EF1 
tornadic winds. The survey then continued into the corn field 
were corn was observed laid down in different directions. The 
tornado then lifted as the track ended in the corn field. 

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

EF0...wind speeds 65 to 85 mph.
