A patchy sheet of cloud covers much of the country's tropical north, due to a monsoon trough running through the Top End and western Queensland. Thick storm cloud surrounds embedded tropical lows along this trough. Another trough extends over the southeast coast of Queensland, bringing a line of thick cloud to the region. Further south, scattered cloud covers northeast New South Wales. A trough from southwestern Queensland over the Sydney/Hunter region extending over the Tasman Sea is bringing a southerly change. Low cloud persists over much of the country's southeast coast from moist onshore flow. Mid to high level cloud can be seen over western parts of Western Australia. The centre of the country is mostly cloud free.
