Weather Situation
A low pressure trough lingering over northern parts of SA gradually moves east today as a high pressure system moves into the Tasman Sea. A stronger high pressure system moves into the Bight from the west on Saturday, pushing the trough out to the far northeast, with a south to southeasterly flow developing across the entire state by Sunday. The high continues to move eastwards, maintaining a ridge over southern parts, as the trough begins to develop in the north again.
