Weather Situation
A high pressure system over the southeast of SA will drift over Victoria on Tuesday before establishing in the Tasman Sea. Meanwhile a broad trough will continue to linger over the far northeast. On Wednesday a new trough will push across the south and settle over the southern pastorals and the east. This trough will be pushed further inland as a southwesterly airstream establishes on Friday with a ridge establishing across the south.
