A high pressure system centred over the Tasman Sea is directing a moist northeasterly airstream over the continent. Scattered low level cloud is being drawn onshore over the eastern seaboard. An upper low over northern New South Wales is driving a thick blanket of mid to upper level cloud with embedded thunderstorms over northern New South Wales, and central and southeastern Queensland. A trough that stretches from central Northern Territory into southern Queensland is driving widespread convective cloud and thunderstorm activity across the northern parts of the country. An upper level disturbance in combination with a surface trough is producing a blanket of mid to high level cloud with embedded thunderstorms over eastern Western Australia, western parts of South Australia, and central parts of the country. A cold front extending into a trough over the southwest of the country is drawing low level cloud over the coastal fringes of southwestern Western Australia. Parts of western Western Australia and Tasmania are mostly cloud free.
