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 from the front into the Northern territory 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.
