Weather Situation
An upper level trough over southeast SA will continue to move eastwards, as a high pressure system starts to build southwest of the Bight. The high will become established south of SA by Friday, then moving eastwards over the weekend to be centred over the Tasman Sea on Monday. A low pressure system well to the south will link to a trough over the far west late Monday and into Tuesday.
