Weather Situation
A trough and cold front clear to the east of the state state overnight, as a high pressure system briefly establishes in the north on Saturday. Another series of troughs and cold fronts are expected to enter western SA early on Sunday, crossing the state and then clearing in the east by the end of Monday. A ridge of high pressure will then push into western SA on Monday before the associated high moves into waters south on Tuesday. A trough over the WA/NT border will also extend into SA at times from Monday.
