Weather Situation
A strong high pressure system centred over Victoria will maintain a ridge across SA as it drifts slowly over NSW. A cold front will then approach from the west late Saturday and move across SA on Sunday, before another ridge pushes in behind the front. The associated high will then move eastwards across waters south from Monday.
