The trough will weaken and stall over the northeast of the state later Sunday. On Monday a stronger cold front with milder southerly winds behind will move through the west and southeast of the state during the day before weakening into a trough over the far northeast on Tuesday. Behind the front a high pressure system will move very slowly towards Tasmania strengthening a ridge throughout the state and generally stabilising conditions particularly over the inland.
