Weather Situation
A significant low pressure system west of TAS continues to move east whilst a second weak low pressure system moves over waters to the south today extending a cold front over coastal parts later today and into Thursday. A high pressure system over WA extends a ridge over western and northern parts on Thursday, before it moves into western SA on Friday, as a cold front embedded in a southwesterly flow clips the south. The high pressure system continues to move slowly eastwards over the weekend, reaching the Tasman Sea late Sunday evening.
