...Summary...
The National Weather Service, with assistance from Hardin County
Ohio Emergency Management Agency, confirms an EF1 tornado nearly
3 miles south of Ada in Hardin County Ohio. This tornado occurred
during the early morning hours on Saturday, December 11, 2021.

The first sign of tornadic damage was observed at a residence just
southwest of the intersection of State Route 309 and 235, where
part of the roof was lifted off a barn and multiple softwood trees
were snapped and blown in multiple directions.

The tornado then strengthened as it moved northeast, causing more
substantial damage at a business and a two story residence, located
on opposite sides of State Route 309, near the intersection with
State Route 235. At the business, two outbuildings were completely
destroyed and part of the roof of another building was lifted
off, with debris splatter noted on multiple sides of this building.
A metal sign was also damaged, and a tractor trailer was overturned
on its side.

At the two story home, the roof was completely lifted off, with parts
of the roof thrown in multiple directions. Several windows were broken,
most likely due to metal debris from the business across the road.
Two outbuildings were completely destroyed. Debris from these outbuildings
and debris from the home were blown at least 0.7 miles in the
field to the northeast. Multiple trees also sustained significant
damage. The tornado was strongest in this area, with maximum winds
up to 110 mph.

The tornado was likely still on the ground in the field to the northeast
of State Route 235, however showed signs of weakening as it
crossed Township Road 55. On Township Road 55, shingles were
removed from one home, while one outbuilding had partial roof
uplift and another outbuilding was moved off cinder blocks. A few
trees along a grove behind the home were also snapped.

Additional minor roof damage was observed on Township Road 64.
This appears to be the end of the tornado, as no further damage
was noted to the northeast.

The National Weather Service in Wilmington thanks the Hardin County Ohio
Emergency Management Agency for assistance with this storm damage survey.
