Weather Situation
A cold southwesterly airstream persists over Tasmania, tending more westerly during today and on Friday as a large high pressure centre establishes over the South Australian coast. The high centre will then slowly cross the southeastern mainland late Friday and during Saturday as a low centre and associated cold front approach Tasmania from the west and cross on Monday.
