As usual, early light rain cleared and was followed by rapid development mostly towards the southwest. A band of thunderstorms approached around 8 – 8:30am. Since the main activity seemed to occur to the southwest, I headed for Rooty Hill only to find that the storms were within striking distance. Within the space of 15 minutes, a spectacular shelf cloud began to develop: definitely the lowest shelf cloud I have ever observed and photographed. It was almost touching the ground and the zoomed photos revealed the presence of an updraught and squall downdraught in the region below the shelf cloud. As expected, the main thunderstorm activity was in this region and general rain followed.
