A low pressure system centred over Kangaroo Island in South Australia is driving patchy cloud over southeastern Australia. West of the low's centre, onshore winds push low level cloud over southeastern Western Australia and parts of central Australia, and the remainder of South Australia. Low cloud is also being driven onto parts of the eastern seaboard by an onshore flow due to a high over New Zealand. High level cloud stretches over much of Queensland and into northern New South Wales, driven by the sub-tropical jet. A surface trough over southwestern Queensland stretches through western New South Wales and western Victoria to south of the low pressure system off the South Australian coast. This system is being reinforced by an upper disturbance, generating patchy low through high level cloud and embedded thunderstorm activity in the region. An trough offshore of southwestern Western Australia is drawing patchy high level cloud over the South West Land Division of Western Australia. The remainder of the country is mostly cloud free.
