Weather Situation
A series of cold fronts are forecast to pass over the state in a persistent west to southwesterly flow on the eastern flank of a high pressure system to the west. The flow will ease later this week as the high pressure system moves closer to Tasmania and extends a ridge over the state on Friday. The ridge is expected to move southeast at the weekend.
