Weather Situation
A low pressure system over the Bight will continue to drive a northerly airstream over Victoria ahead of an approaching cold front in eastern SA. This front will cross Victoria on Thursday with the associated low moving south of Tasmania. A second weaker front will skim the south late Friday into Saturday morning before a high pressure system over SA extends a ridge into Victoria on the weekend.
