Overview
|
Thunderstorms developed in portions of New York and Pennsylvania during the afternoon on May 15, quickly forming a well-organized quasi-linear convective system (QLCS) with embedded bow echoes. Widespread wind damage occurred with the QLCS as it moved rapidly eastward into southeast New York, eastern Pennsylvania, and northern New Jersey by late afternoon. The most significant damage occurred near and north of the Interstate 78 corridor, with dozens of reports received from Carbon, Monroe, Northampton, Sussex, Warren, and Morris Counties. One fatality occurred in Monroe County as a tree fell onto a vehicle, killing the occupant. The QLCS weakened by early evening as daytime heating waned and the storms approached a stable marine layer over and adjacent to the Atlantic Ocean.
