A deep upper low is driving a surface low pressure system and a trough the interior of Western Australia. A couple lines of thunderstorms can be seen in the vicinity with mid level cloud over the eastern side of the state, also flowing over South Australia. A series of upper troughs over the southeast of the country are bringing convective cloud and thunderstorm activity to eastern New South Wales and southern and inland Queensland. A heat trough stretches from central Northern Territory, through Queensland, into southern New South Wales which is also contributing to thunderstorm activity across those states, with associated low to mid level cloud. Low level cloud is present over Tasmania and Victoria, pushed onshore by a high pressure system south of the Bight.
