Weather Situation
A weak low pressure trough located to the east of Tasmania is expected to move away into the Tasman Sea into Saturday. A trough is expected to cross Tasmania on Saturday ahead of a cold front expected to pass over the state on Sunday. A high pressure ridge is then expected to develop over Tasmania from the west into the new week, with a series of troughs to pass to the south of the state embedded in the westerly flow.
