A thick band of cloud with widespread thunderstorm activity is over eastern Western Australia, the Northern Territory, South Australia and The Great Australian Bight. This is associated with an upper air disturbance to the west. Thunderstorm activity continues over the NT Top End, the Gulf of Carpentaria and Cape York. Moist onshore flow is pushing low cloud onto the east coast of Queensland. A high pressure system to the south of the mainland is bringing patchy low level cloud to the southern coasts of WA, SA, Victoria, and western Tasmania. The rest of the country is mostly cloud free.
