Weather Situation
A high pressure system is centred over central SA, the high will continue moving to the east while extending a ridge over SA on Thursday. A low pressure trough is then forecast to approach and linger about western parts late on Thursday until early Saturday. Another high then moves across waters to the south, extending a ridge across much of the state over the weekend.
