Weather Situation

A high centred to the south of Tasmania will drift eastwards, allowing a southeasterly stream to tend easterly this evening. Winds will then tend north to northeasterly on Wednesday as the high moves over the Tasman Sea. A cold front will cross the state Thursday afternoon, replaced by a weak ridge in the evening, before another cold front early Friday and an associated low passes to the south. A cold southwesterly flow will persist as an embedded trough crosses early on Saturday.
