Weather Situation
A high pressure system southwest of SA extends a ridge over much of the state, as a cold front clips the southeast early Tuesday. The high will quickly move in behind the front and maintain a ridge over SA as it moves to the east of Tasmania by Thursday. A strong cold front is then expected move into the Bight later on Thursday and move east across the rest of SA on Friday and early Saturday.
