A ridge of high pressure extends over the eastern half of the country, resulting in patchy low level cloud over the east of Australia. A weakening cold front moves through Victoria, generating a streaky band of cloud through all levels of the atmosphere. Behind this front, speckled low level cloud is being driven onshore through coastal parts of South Australia and Victoria, indicative of a cold moist airmass originating from the Southern Ocean. A trough over the Indian Ocean brings a thick sheet of mid to upper level cloud to central parts of Western Australia. The rest of the country is mostly cloud free.
