Weather Situation

A cold front and low lie to the east of Tasmania, and a high over the Bight extends a weak ridge over the state. This pattern is combining to produce a cold southwesterly flow which will moderate and tend westerly, as a weaker front passes to the south during today. A westerly stream will continue on Monday with a weak embedded trough to cross Tasmania during the morning, then freshen and tend northwesterly on Tuesday as a cold front approaches from the west.
