A high pressure system over the southern Tasman Sea is directing fresh east to southeasterly winds with areas of low cloud onto the eastern seaboard. An atmospheric river of mainly middle and high level thick cloud is flowing over central Western Australia, Northern territory and Queensland. A large cloud band is situated through South Australia into Western Victoria ahead of an approaching trough in the Bight. Significant thunderstorm activity is being observed through the Eyre Peninsula and North East Pastoral district of South Australia. "Speckled" cold-air cloud can be seen along the southwest coast of Western Australia as a ridge of high pressure directs moist air onshore.
