A dynamic low pressure system tracked just to the north of the area with low CAPE but a strongly sheared environment developing in the warm sector of this system. This encompassed the southern portions of the area. Strong low level speed and direction shear was present with wind speeds up to 65 knots off the ground. A line of storms developed along a pre-frontal trough and moved across the region during the evening hours. Initial storms were further supported by a mid-level low that resulted in multiple hail reports. This area of storms evolved into a linear structure with multiple waves of stronger wind moving northward along the boundary. This line began producing wind damage with periods of diffuse rotation near these waves.
