The ridge will move southeast today as the high centre moves to a position well south of the Bight. The high will pass over Tasmania on Friday and a trough will move over the far west of SA. This trough will move slowly over the state during the weekend to reach eastern districts late Saturday. A second low pressure trough is expected enter the far west of SA on Sunday.
