A low pressure trough stretches across the country from southwestern Western Australia, through the Northern Territory and Queensland, into northern New South Wales. Extensive thunderstorm activity surrounds the trough in Queensland. Low cloud covers streams off the coast of eastern Victoria and eastern New South Wales in the westerlies behind a coastal low pressure system and trough which stretches into the Tasman Sea. Thunderstorm activity can be seen to the west of the Low over the Mid North Coast of New South Wales. An upper disturbance and a surface trough in the vicinity is driving a band of thunderstorm activity and associated upper cloud over southern Western Australia. Rainfall from the system has developed low level cloud over southwestern Western Australia. A trough approaching the southeastern coast of South Australia is bringing low cloud to the state. A cold front approaching the southeast of the country is currently passing over southwestern Tasmania.
