Weather Situation
A weak ridge extends over Tasmania from a high pressure system over the central Tasman Sea. The ridge weakens further Thursday, as a trough approaches from the west in the evening. Another weak trough is forecast to move over the state from the west during Friday ahead of a cold front to cross later. A secondary high pressure system is forecast to extend a ridge over Tasmania from the southwest during Saturday, and move over on Sunday.
