A thick cloud deck stretching from central Australia, over the southeast and off into the Tasman Sea is being driven by a surface low pressure system and is reinforced by an upper air disturbance. High level cloud streams out of the system and into northern Western Australia. A broad area of low pressure is driving extensive convective cloud with embedded thunderstorms over central Western Australia. Onshore airstreams are bringing low cloud to the Top End and coastal parts of northern Queensland. A lengthy cold front is visible far to the southwest of Western Australia. The rest of the country is mostly cloud free.
