A weak high pressure system will sit over the north of the state with a weak cold front crossing through Bass Strait during Tuesday. The high pressure system will shift eastwards, positioning itself over the Tasman Sea on Wednesday resulting in weak ridging over waters. A trough will sweep across the Ports on Thursday, followed by a weak ridge of high pressure extending on Friday resulting in a southwesterly airstream.
