Weather Situation
A high pressure system centred south of the Bight extends a ridge over SA. The high will move eastwards to be centred near Tasmania on Sunday and Monday but will continue to extend a ridge over SA. The ridge will weaken mid next week as a trough moves over western coasts then a cold front will move across from the west late Friday and early Saturday.
