Weather Situation
A trough over northern parts of the SA will drift south again later this week as a high pressure system moves east into the Tasman Sea. The trough is forecast to move to the northeast on Saturday as a strong high pressure system extends a ridge into the Bight, with a south to southeasterly flow developing across the entire state by Sunday.
