Episode Narrative Numerous strong to severe thunderstorms occurred in the warm sector of a low pressure system over central Missouri. The air mass in the warm sector was very unstable, with afternoon mixed-layer cape values in the 2500 to 4000 j/kg range. A 65 to 75 knot mid level jet was located across Arkansas, with the nose of the jet moving into western Kentucky. This feature enhanced the lift and strong deep-layer shear already in place, creating an environment very favorable for supercells and tornadoes. A 40 to 55 knot low level jet across eastern Arkansas moved into western Kentucky during the evening, resulting in isolated tornadoes and widespread damaging winds.
Event Narrative The tornado started north of St. Wendell, where trees were damaged along with a machine shed. As it moved across Highway 65, high-tension power lines were taken down. Peak winds were estimated near 125 mph. The tornado continued moving northeast into Vanderburgh County.
