A trough over central Australia will weaken and contract into WA as a ridge of high pressure extends across southeastern SA. The high pressure system is expected to drift into the Tasman Sea by Tuesday as the trough in WA begins to re-extend over western SA on Tuesday, pushing into the state on Wednesday and reaching the far northeast on Thursday.
