A broad area of mid to upper level cloud with some isolated embedded thunderstorms lies across central and southern Western Australia, primarily due to the presence of an upper trough in the region. Some areas of low cloud are also visible in the far southwestern corner of the state as a moist airmass moves through. Isolated patches of low cloud are visible over Western Tasmania, southern Victoria, and southeastern parts of South Australia. This is due to a moist airmass originating from the Southern Ocean becoming trapped underneath a ridge over the continent. Patches of low level cloud linger over parts of the eastern ranges in Queensland and New South Wales, the result of moist onshore flow being driven by a ridge up the coast. The rest of the country is mostly cloud free under the influence of a large, dominant high pressure system centred over the Great Bight.
