Weather Situation
A high pressure system centred over mainland Australia extends a ridge southwards over Tasmania. The ridge is expected to move to the east of the state throughout today. A light northerly airstream builds over Tasmania during Saturday, as a broad low pressure trough to the west of the state is forecast to move over the southern mainland during the weekend.
