An extensive upper level cloud band streams from northwestern Western Australia, across South Australia and over the Queensland and New South Wales border. A cold front is passing over southwestern Western Australia with associated low to mid level cloud. An upper level trough is generating mid level cloud with isolated thunderstorms through the central Western Australia. A cold front is situated off the central New South Wales coast, generating patchy low to mid level cloud in its wake through southeastern New South Wales. A high pressure system in the Tasman Sea extends a ridge over northern and eastern parts of the country, driving some patchy cloud along the eastern seaboard. The rest of the country is mostly cloud free.
