...Summary...
A weak tornado occurred on the evening of July 22, 2018 in 
Heidelberg Township, PA. The tornado caused tree damage along 
Church Road before tracking through a cornfield and eventually 
causing damage to the metal roofing on a barn at the Heidel Hollow
Farm on Saegersville Road. The well defined path through the corn
field and twisted nature of the tree damage and eye witness 
accounts helped to determine this was tornadic damage. The damage 
was sporadic along the 0.8 mile path, especially through the 
cornfield, so the tornado may not have been on the ground for the 
entire path.

Appreciation is extended to the Southeast PA Skywarn Coordinator,
officials from Germansville Fire Department, Heidelberg Township 
Emergency Management, and Lehigh County Emergency Management for 
their help in this storm survey.
