Weather Situation

A high pressure centre lies over the Bight and extends a ridge to the north of Tasmania, directing a west to southwesterly airstream over the state. A cold front slowly moves over the state late this evening and early Thursday. The high in the Bight moves eastwards over the Tasman Sea on Saturday, directing a much warmer northerly airstream over the state which strengthens as a cold front approaches from the west late Saturday.
