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 cross south SA and bring a following trough across southern coasts late Sunday.
