Weather Situation

A slow-moving high pressure system over the Tasman Sea extends a ridge over eastern SA. A trough of low pressure over western SA is moving eastwards and will reach southeastern parts later today while a weakening cold front crosses the Bight. The trough lingers in the east through the middle of the week as a weak high pressure system forms in the Bight. This trough weakens on Thursday as a second trough moves into the west from WA.
