- Weather Situation
- A high pressure system over the Bight extends a ridge across the south and east of the state while an inland trough remains over the northern and central inland. During today, the high pressure centre is forecast to move over the state into the Tasman Sea. The next trough enters the far southwest and moves across the state on Thursday, reaching the far northeast corner by Friday. Over the weekend another high pressure system over southeast Australia extends a ridge over the state, as the high becomes near stationary once it settles in the south Tasman Sea.
