Summary:

The tornado initially touchdown just south west of Brindlee 
Mountain Primary School. At this location, the school gymnasium, 
10 classrooms, and the cafeteria were destroyed. Numerous beams in
the roof of the gym were also twisted and bent, and large bolts 
used to attach it to the foundation were ripped from the 
structure. EF2 tornado damage was determined at this location, 
with wind speeds 120MPH. In addition to damage to the school, 
several trees were snapped or uprooted at this location near the 
ballfield. A set of bleachers was hurled over 150 yards from one 
side of the school to the other. Several dumpsters were displaced 
as well, along with three or four power poles snapped at their 
bases. This lead to additional damage at the school property when 
the poles fell on the school awning and roof. Little to no 
additional tornado damage was noted to the northeast of the 
school, aside from roofing materials strewn from the damage at the
primary school itself. The tornado ended as it crossed Union 
Grove Road west of the Union Grove Fire Station.

Special thanks to Marshall County EMA with their assistance on 
the storm surveys this afternoon.
