The Massey Tornado in Southern Morgan County was associated with
the long lived parent supercell that migrated eastward from the
AL/MS state line. The damage assessment team consisting of NWS
Huntsville and Morgan County EMA concluded that the impacts in
Southern Morgan County were consistent with an EF-1 tornado.
Widespread tree damage (snapped and uprooted) was observed across
the path as the tornado and parent supercell dove southeast from
near the CR55/Summerford Rd area to Wilhite Rd (east of I 65 on
the the Cullman/Morgan Co border). Only structure damage to note
was a couple small farm structures and sheds that were heavily
damage or destroyed adjacent to Evergreen Rd, consistent with
EF-1 damage. Damage indicators became more widely scattered as it
approached I-65, but several trees were observed damaged along
Wilhite Rd. The tornado then continued into Cullman County where
it weakened with EF-0 damage observed in northern Cullman County.
