The majority of the country is cloud free. A thick band of cloud through all levels of the atmosphere moves through the southern half of Western Australia due to a low pressure trough in the region. A low offshore of the east coast is directing patches of low to mid level cloud across coastal parts of northern New South Wales and southeast Queensland. A thick field of low level cloud and fog is present over western Victoria, and can be seen creeping across the border into parts of South Australia and New South Wales. This is due to cold overnight temperatures under a strong high pressure system. An upper trough moving through the Southern Ocean is bringing a sheet of mid to high level cloud over much of Tasmania. Scraps of upper level cloud extend further north, reaching coastal parts of Victoria and South Australia.
