Much of southern Western Australia is covered by a thick sheet of mid to upper level cloud, the result of low pressure system is drawing in tropical moisture south across the state. This cloud is thickest near the low, which continues to move south-southeastward off the southern Western Australian coastline. Scattered low to high level cloud across the Top End is due to thunderstorm activity. Low cloud kisses the South Eastern Seaboard in the wake of a decaying low pressure system situated well east over the Tasman Sea. A strengthening high pressure system slowly moves through the Bight, bringing patchy low level cloud to parts of Tasmania, Victoria, and south and southeastern South Australia. The remainder of the country is mostly cloud free.
