A cloud band extends over the centre and southeast of the continent due to an upper air disturbance. A cold front located through western South Australia is drawing in cold low to mid level cloud from the bight over southeastern Western Australia. A trough extends through Central Australia producing mid level cloud with embedded thunderstorms. Low cloud is being driven onto parts of the eastern seaboard by the pressure gradient between a high in the southern Tasman Sea and a low near New Caledonia. Low level cloud is pushing onto the southwestern coast of Western Australia due to a high pressure system in the area. Mid to low level cloud is seen over tropical Queensland and the Top End.
