Thunderstorms developed along the Lake Erie lake breeze boundary and pushed inland from Chautauqua County toward Wyoming County. These cells pulsed up and down a few times and displayed lightning jumps at times. This resulted in sporadic wind damage. A second cluster of cells moved inland from Lake Erie overnight. These cells results in marginally severe wind reports that with wind gust reports being well represented by the New York State Mesonet observations. Shear was rapidly increasing as these cells were moving in, too, so the expectation was that they would grow stronger as they moved into the area, which is what occurred.
