Scattered thick cloud with plenty of embedded thunderstorm activity covers much of the country's tropical north. A thick band of upper level cloud resulting from this tropical activity extends further south, covering much of northeastern New South Wales, and southern and western Queensland. A trough off the central coast of Queensland is streaming thick cloud and thunderstorm activity over the Mackay coast. Thick low level cloud drifts over much of coastal Queensland and northeastern New South Wales. This is due to moist onshore flow being driven by a high pressure system in the Tasman Sea. Similarly thick low level cloud to the west of a trough is present over far southwestern parts of Western Australia. An upper trough over Tasmania is driving a streaky band of mid to upper level cloud over Tasmania and southern Victoria. The rest of the country is mostly cloud free.
