Weather Situation
A cold front will move across the state from the west today. A high pressure system moves into waters south of the Bight and extends a ridge over Tasmania on Thursday. That high then moves into the Tasman Sea on Friday, directing a northerly stream over the state ahead of a cold front expected over the weekend.
