Weather Situation
A strong high pressure system over the Tasman Sea will maintain a ridge across South Australia through to Friday. Northerly winds freshen on Friday ahead of a front that is forecast to move across the far west Friday afternoon, then continue across the state during the weekend. The low pressure system associated with this front is expected to linger over waters to the south of the state resulting in a trough moving over southern parts later Sunday and Monday. The low will then move into Bass Strait on Monday.
