Weather Situation
A trough lies in the state's far west and a high pressure system lies over the Tasman Sea, maintaining north to northeasterly airstream. The trough will become mobile tonight and enter the far south coast Sunday morning as a cold front passes to the south. Then, the system will cross Sydney Waters on Sunday evening, bringing a fresh to strong southerly wind change in its wake. Southerly winds will gradually ease and turn east to southeasterly early next week as a new high enters the Bight and extends a ridge across the coastal waters.
