A broad band of mid to high level cloud with embedded thunderstorms stretches from central Queensland, down the eastern coast of Australia, and over Tasmania. This cloud band has been driven by an upper air disturbance. Low cloud covers Victoria and southern New South Wales in the systems wake. Thunderstorms are also active in central parts of Northern Territory and the over northeastern Western Australia. A high pressure ridge in the Bight has driven low cloud over southern Western Australia and South Australia. Patchy high level cloud is also streaming over southwestern Western Australia. Central western and south central parts of the country are mostly cloud free.
