- Weather Situation
- A ridge extends over the south of the state from a high pressure system to the west of the continent. A trough and cold front will clip the southeast of the state this morning as the main high pressure centre moves over the Bight. The high will weaken and move eastwards on Thursday ahead of a more vigorous trough expected to cross the state on Friday. A ridge is expected to return to the south on Saturday from a high centred well to the west of WA.
