Location: (ABE)LEHIGH VALLEY INTERNATIONAL AIRPORT
Tornado F-scale: EF1
Reported by: NWS Storm Survey

On the evening of August 7th, an EF-1 tornado occurred, primarily in the Midway Manor neighborhood of Allentown, Pennsylvania. The tornado began near East Pennsylvania Street between North Ulster Street and North Van Buren Street. At this location, damage to the roof of a church and a neighboring shed was seen with multiple shingles removed and displaced. A large hardwood tree was also uprooted in this area, falling to the north as it was uprooted. The tornado then continued to the northeast towards East Lily Street and North Wahneta Street causing sporadic tree damage along the way. As the tornado crossed North Wahneta Street, the amount of damage began to increase with a shed removed from its foundation and tossed about 50 feet northwest. Multiple trees were uprooted or snapped in this area as well. As the tornado continued to the northeast, approaching and crossing East Fairmont Street, it reached its maximum width, around 160 yards. It is also reached its maximum intensity, causing damage to multiple homes. The greatest damage was to homes along the west side of Club Avenue, where multiple homes lost between 30 and 50 percent of their roof covering. One home had a front porch awning taken off the east side of the house, lofted, then landed about 100 feet away in the backyard of a house two doors down. Additionally, damaged crops in the backyard of a home where fallen in a manner consistent with a convergent wind pattern. The tornado continued northeast across Club Avenue, crossing into Bethlehem, Pennsylvania. Here, the tornado began to weaken, but still snapped or took large branches down on multiple trees. The tornado then dissipated as it approached Pennsylvania Avenue. No known injuries or fatalities occurred with this tornado.
