Thunderstorm Wind in Cameron County, Pennsylvania

A severe thunderstorm, producing wind gusts estimated near 60 mph, knocked down multiple trees and wires near Beechwood Road near Truman.

An MCV approaching from the Upper Ohio Valley began tracking into Ohio during the late afternoon and evening hours where a more favorable environment over western and central Pennsylvania allowed for a cluster of severe thunderstorms. Ample shear in the realm of 40 to 50 knots, CAPE values between 1000 to 1500 J/kg, and increasing low-level moisture allowed for an increase in severe potential as thunderstorms entered central Pennsylvania during the evening hours. An initial cluster of thunderstorms began to split the border between New York and Pennsylvania, with ample low-level shear allowing for broad rotation within these storms. Multiple instances of tree damage were observed in McKean County, with an observed 60 mph wind gust in Potter County. A secondary cluster of thunderstorms later in the evening caused isolated tree damage in both Cameron County and Elk County. This cluster of thunderstorms weekend slightly downwind of the Allegheny Plateau, moving through sparsely populated areas of northern Clinton, northern Lycoming, Potter, and Tioga counties before moving into eastern Lycoming County. In eastern Lycoming County, multiple instances of damage to structures were reported north of Williamsport with multiple instances of tree damage observed before thunderstorms shifted east of the region.
