A high pressure system centred over New South Wales will drift east over the Tasman Sea today allowing a cold front to move across the Bight. The front is forecast to continue to move east across southern South Australia on Tuesday, followed by a new high pressure system moving into the Bight on Wednesday. This new high is expected to move slowly east to be over Victoria later this week.
