The tornado began west of the intersection of Parmer Drive and Price Road
in Halifax Township, where it tore off a few foot section of the roof of
a barn. The path then continued north to northeast, crossing Powells Valley
Road. A row of trees was knocked down in a circular (counterclockwise) pattern,
with a densely populated grove of trees being snapped and uprooted in varying
directions to the east of that location. This is where the EF-1 damage began. 
Farther northeast and north of Hoover Lane, another grove of trees was snapped
and knocked down in numerous directions. This was the end of the EF-1 caliber 
damage, with the tornado continuing to track northeast producing EF-0 intensity 
damage. Just north of Ridge Road and west of Hershey Road, a wheat field
had several individual plants flattened, prior to the tornado lifting.
