Weather Situation

A high pressure ridge over SA will move to the east during this morning, as a trough moves over the state during the day, followed by a strong cold front early Saturday. A high pressure system will then move across the state, behind the front, and merge with another high located to the southwest of WA on Sunday to extend a ridge across much of SA into next week. A low pressure system is also expected to move in vicinity of the WA border late Sunday and may extend a trough into far west SA into next week.
