Wider weather episode

During the afternoon and evening hours on October 12th, a mid- and upper-level trough and associated surface cold front moved across central Kentucky. Ahead of the front, temperatures warmed into the low-to-mid 80s, with dewpoints remaining fairly modest in the upper 50s and lower 60s. This contributed to around 1000-1500 J/kg SBCAPE and MUCAPE in the pre-frontal environment. The instability ahead of the front combined with approximately 40 knots of effective bulk shear to produce two waves of strong-to-severe storms across Kentucky. The first wave of storms were more discrete and cellular in nature, producing sub-severe hail across Russell County. The second and more potent wave of storms was a quasi-linear convective system which developed along the surface boundary, brining damaging straight-line winds to portions of Metcalfe County.
