Weather Situation
A high pressure system south of the Bight extends a ridge over SA. The high will slowly move east over the weekend ahead of a cold front which will slip to the south of SA and weaken. The high will remain near stationary in the southern Tasman Sea, maintaining a ridge across the state early next week.
