Weather Situation
A trough is approaching from the west and will move across SA on Sunday, as an upper level disturbance moves over the far west later on Sunday. A high pressure ridge will also extend into the state from a high located southwest of WA from late Sunday. A cold front will then slip across southern coasts late Monday and early Tuesday, before the high moves across waters to the south to be centred over Victoria by Thursday.
