The following events were reported: Thunderstorm Wind, Tornado. These occurred near station USW00094823, approximately 38.3963 km away, between 2017-07-10 14:57:00 and 2017-07-10 15:30:00.Thankfully, no injuries or fatalities were reported. The events caused property damage valued at 37500.0 and crop damage of 0.0. Episode Narrative: Shortwave digging through an upper trough helped to develop two convective systems that crossed the upper Ohio Valley on the 10th. Moderate instability and shear provided for intensification of the second system over central and eastern Ohio but both produced scattered reports of wind damage. An EF-0 tornado was also confirmed in Beaver county, Pennsylvania that then continued into Butler county. Shortwave digging through an upper trough helped to develop two convective systems that crossed the upper Ohio Valley on the 10th. Event Narrative: National Weather Service survey team confirmed a tornado near Fombell in Beaver County that continued into Lancaster Township in Butler County in Western Pennsylvania on Jul 10, 2017. A coherent, continuous swath of damage was discovered from near Bowers Lane/North Camp Run Road in Fombell east-northeastward to near the Strawberry Ridge Golf Course in Lancaster Township. Damage was universally to trees, consisting of snapped large limbs and trunk snappage or uproots of both healthy and unhealthy trees. At its most significant, the damage exhibited a rotationally-convergent debris pattern consistent with a weak tornado as it traversed a hillside through the golf course. Observers on the golf course at the time of this storm event reported tree debris being lofted and swirled cyclonically, which was consistent with the debris pattern noted by the survey team. Although not an accepted damage indicator, corn stalks just upstream from this location also were laid over and exhibited a swirl pattern. It should be noted that no structural damage was discovered at any point through the survey path. This lack of damage to structures enables the team to cap the storm's estimated wind speed. Farther to the northeast (at least as far as Eagle Mill Road and Whitestown Road), a coherent, discontinuous damage swath was noted, but lacked sufficient conclusive evidence to identify its origin. It is entirely possible that this damage was an extension of the tornado, but the debris was too sparse for any conclusions. The survey team has concluded that a brief, weak tornado occurred from near Bowers Lane through at least the Scott Ridge Road/McNulty Lane area. The damage was consistent with a tornado of peak wind speed of 60-70 mph, which yields a rating of EF0 on the Enhanced Fujita Scale. National Weather Service survey team confirmed a tornado near Fombell in Beaver County that continued into Lancaster Township in Butler County in Western Pennsylvania on Jul 10, 2017. Trained spotter reported several trees down on little creek and Hartmon Roads. National Weather Service storm survey discovered trees and limbs down along Rabbit Road. State official reported a tree down. Member of social media reported two trees down. NWS Employee reported a 60-70 foot pine tree with a diameter of 20 feet was snapped a couple of feet off the ground.
