Weather Situation

A high centred near New Zealand and an approaching trough and cold front are directing a locally warm north to northeasterly flow over Tasmania. The trough will slowly cross Tasmania during Friday with winds to tend light and variable later as the cold front approaches the west. The front will cross Tasmania Saturday morning, as winds tend southerly, with a high to slowly move south of the Bight during the day. The high will move to the west of Tasmania during Sunday as a low deepens to the east of the state and the southerly flow continues.
