Weather Situation
A west coast trough will move offshore on Sunday and a weak low pressure system will develop within the trough, as a high pressure system strengthens in the Bight. The high will move east on Monday, allowing the trough to return to the west coast. The trough will move inland ahead of a cold front brushing the south coast on Tuesday. A new ridge will build across the southwest coast from Wednesday.
