The storm developed as a southeast change moved through Gold Coast Hinterland and warm moist air and cooling air aloft overrode the this warm layer. A few thunderstorms developed but one in particular exploded with huge powerful updrafts and raced in a straight path to the city of Brisbane CBD. the first of the violent winds hit Archerfield with wind gusts to least 140km/h and then the well developed supercell powered on towards the city of Brisbane. Thousands of cars were damaged by large to giant hailstones and homes were unroofed and trees toppled onto them. The storm was described to be "the worst in a decade".
