A high pressure system over Tasmania will move over the Tasman Sea during today, ahead of a low pressure trough and associated cold front approaching from the west. The trough is expected to cross the state during this afternoon and evening, with associated cold front to cross the south of Tasmania late. On Wednesday a high pressure system south of the Bight is forecast to extend a ridge over the state, with the high centre to cross Tasmania on Thursday and linger over the Tasman Sea into Friday as another high centre builds over the Bight.
