Weather Situation
A high pressure ridge over Bass Strait will move to the east today as a low pressure trough over eastern NSW develops into a low pressure system. That low is expected to move south on Friday and clear to the southeast on Saturday. The flow will tend northwesterly and freshen across Victoria on Sunday ahead of a strong cold front passing over the state early next week.
