Wider weather episode

A cold front moved across the area on the evening of June 28th. Convection developed quickly along the front as the cap eroded, initially discrete but quickly growing upscale. Robust CAPE exceeding 3000 J/kg was in place with good directional shear to support rotating updrafts. This resulted in a handful of weak tornadoes in Cass county at the onset of storm development. After storms grew upscale they remained sub-severe.
