A broad westerly airstream persists over Tasmania until a cold front is expected to cross from the west during Saturday afternoon. Westerlies return on Sunday, as a high pressure system over mainland Australia moves into the Tasman Sea by Monday. Winds are expected to shift northerly on Monday as the high sits over the Tasman Sea and a low pressure system deepens well to the west of Tasmania over the Southern Ocean.
