A cold front west of Tasmania is bringing a thick band of mid level cloud into southern New South Wales. A cool air mass follows behind it, bringing spotty low level cloud into Victoria and the west side of Tasmania. Significant thunderstorm activity is driving an area of mid to high level cloud about central Australia, close to an inland trough extending from the northern interior of Western Australia to the south east coast of the country. Some remnant low to mid level cloud can be seen in the Top End and the Kimberly region of Western Australia. A high pressure system is pushing extensive low level cloud into the bottom half of Western Australia and the Great Australian Bight.
