Weather Situation
A broad trough of low pressure lingers over the east and northern parts of the State. A low pressure system lies south of the bight and moves east to combine with the trough early Sunday. The combined low pressure system and trough then moves east to clear SA by late Sunday. A high pressure ridge then extends over the west and south of the State behind the low pressure system during Sunday. The high pressure ridge extends across the entire State and Coastal Waters by late Sunday and persists from Monday to Thursday.
