- Weather Situation
- A slow moving high pressure system is east of Tasmania, directing a mild to warm north to northeasterly airstream over the state. The high is expected to move further east to be over the New Zealand by Friday. A trough is expected to approach the west of the State late Friday, and move over late Saturday. A more significant cold front is then expected to approach from the west later Sunday.
