Strong daytime heating and humid air destabilized the atmosphere during the late morning and early afternoon hours. Turbulent clouds developed along a west to east low-level confluence boundary and were aided by wind shear of 30 to 35 knots at low- to mid-levels of the atmosphere. These conditions increased the number and intensity of thunderstorms during the late afternoon and early evening. They produced damaging winds across Indiana from west to east just south of Indianapolis.
