Broad areas of thick storm clouds cover much of the country's tropical north, due to low pressure troughs and excess moisture through the region. Patchier mid to upper level cloud is also visible through this area. A thick band of mid to upper level cloud persists over southeastern Queensland. A trough extending through the interior of Western Australia brings a streaky arm of low to mid level cloud to the region. A patchy sheet of mid level cloud drifts over southeastern parts of South Australia. A ridge of high pressure to the country's southeast drives moist onshore flow and low level cloud to the southern New South Wales coast, along with much of Tasmania.
