Weather Situation
A low pressure system over the Bight is combining with a high pressure system over the Tasman Sea to direct a warm northerly airstream across Victoria. The low will move slowly south during today before a front associated with the low crosses Victoria on Thursday. The low will weaken and move to the southeast of Tasmania on Friday as a cold front approaches from the southwest. A high pressure system will move south of the Bight during Saturday as the front crosses southern Victoria.
