Weather Situation
A trough will linger inland over the west until a cold front sweeps across southern SA on Thursday. This front will push the inland trough into the far north, exiting the state early Friday. A cooler southwest to southerly flow will gradually moderate in the wake of the front as a strong high pressure system moves in from the west from Friday, establishing in the Bight on Sunday.
