The wider storm

On September 4, a pre-frontal trough and cold front crossing the region caused severe thunderstorms to develop across the eastern half of the Buffalo forecast area. With 40+ knots of 0-6 km shear available and CAPE values of around 1,000 J/kg for areas east of the Genesee Valley. As showers along the trough and front encountered this more favorable area and thunderstorms developed and became severe with damaging wind gusts.

Began near Geneva (42.8600, -76.9900).
