Weather Situation
A high pressure system centred near Adelaide maintains a ridge over SA, and is expected to track eastwards, moving over the Tasman Sea late Wednesday into Thursday. A broad low pressure trough is expected to form over western parts of SA on Thursday and move eastwards across the state, clearing away to the east by Saturday. Behind the trough a high pressure system southwest of WA will extend a ridge over SA over the weekend.
