Survey Summary:
A brief EF-0 tornado occurred near Route 147 in Upper Paxton
Township, Dauphin County. The National Weather Service Office in
State College, PA conducted a storm survey of the area to
investigate the damage. Trees were downed by the tornado, blocking
the roadway at 3462 PA 147. The tornado damage was intermittent as
it traveled east for about 1 mile, downing more trees as it
crossed over Shippen Dam Rd. The survey also found a larger area
of more sporadic, non-tornadic wind damage to the north of the
tornado track, which extended nearly 20 miles from Seven Stars in
Juniata County to Gratz in Dauphin County. This damage mostly
consisted of downed trees and tree limbs, as well as downed
powerlines on Specktown Road in Lykens Twp, Dauphin County. It was
determined that this larger area of sporadic damage was
associated with the forward flank downdraft of the same storm,
which is an area of straight line winds within a supercell. We
would like to thank Perry County and Dauphin County for their
assistance with this survey.
