Weather Situation
A cold front is crossing Tasmania this evening with a cold southwesterly airstream to follow early Wednesday. The airstream will then tend more westerly during Thursday and Friday as a large high pressure centre establishes near the South Australian coast. The high centre will then slowly cross the southeastern mainland later Friday and during Saturday as a low centre and associated cold front approach Tasmania from the west.
