Weather Situation
A ridge of high pressure extends over Victoria from a high pressure system centred over the Tasman Sea. The ridge will weaken over the weekend as the high moves away to the southeast and a low pressure system develops over the south of SA. This low is expected to move inland across southern SA on Monday and early Tuesday then move over NSW during Tuesday and extend a trough over Victoria. The low and trough will move slowly eastwards on Wednesday.
