National Weather Service storm survey team investigated storm
damage in Morgan, Roane, Loudon, Knox and Blount counties. These
storms did exhibit some weak rotation aloft on radar at times as
the line of storms passed through these counties, but no tornado
paths were found by the survey team. The majority of the damage
consisted of downed trees with damage to structures due to trees
falling on the structures. Winds within the damage areas were
estimated at 70-80 mph.
The overall event that marched through the area was a derecho,
with widespread thunderstorm wind damage. Within the derecho, a
Bow echo surged forward in these counties where the strongest
winds were indicated.
