An upper air disturbance in the Indian Ocean is responsible for a streaky arm of high level cloud streaming across central Western Australia, southern parts of the Northern Territory and much of South Australia. The patchier extremes of this cloud band is extending as far east as southern Queensland. Patches of thick convective cloud with embedded thunderstorms can be seen along the New South Wales coastal fringe, associated with a trough and active low pressure system approximately 500 kilometres offshore of Coffs Harbour. Moist southeasterly trade flow and a weak trough offshore is generating patchy low cloud over the North Tropical Coast of Queensland. Further north, a thin sheet of mid level cloud lies over the tip of Cape York Peninsula. A fast moving cold front south of the Bight is bringing some wispy low to mid level cloud in southeastern parts of Western Australia. Cold onshore flow in the wake of this front is also bringing patches of convective cloud along the state's southwest coast. The rest of the country is largely cloud free.
