The same supercell that produced a tornado in Grant
County moved east and underwent several storm mergers as it moved
over eastern Grant County. The merger caused the thunderstorm to
shift southeastwards with time before mirroring the Blackford and
Wells County lines. This thunderstorm produced a tornado with
multiple vortices, and had a width of approximately 1200 yards at
its widest. This tornado tracked from north of Roll, IN to north of
Montpelier, IN to near Nottingham, IN. The tornado lifted just east
of Highway 1. There were two significant injuries reported at a
dairy farm where EF-3 damage occurred.  EF-3 damage was observed in two locations. The first was at a dairy
farm on county road 700 West north of the county line. A well built
structure sustained major damage consistent with winds of 165 mph.
Numerous other buildings at this location sustained significant
damage and several cows also died. Further east, about 1 mile east
of county road 500 west, a large power transmission tower was
toppled in the middle of a field. Winds were estimated at 140 mph at
this location. Numerous other buildings sustained EF-0 to EF-1
damage and some EF-2 damage was also observed. Many trees were
topped or uprooted all along the path of this tornado.
