Weather Situation
A high pressure system over the Tasman Sea directs a northwesterly flow over Victoria, strengthening this morning ahead of a trough which will cross the state later today. Another weak trough and low pressure system are expected to move over Victoria on Friday, before a cold front moves over the south during Saturday. A ridge of high pressure is then forecast to build over the state on Sunday.
