Weather Situation

A high pressure ridge will remain over northern parts of SA, as a cold front slips across the southeast early Thursday. The ridge will move to the east early Friday as a trough moves over SA during the day, followed by another cold front early Saturday. Another high pressure system will move across the state, behind the front, and will extend a ridge across central and eastern parts of SA into Sunday. A low pressure system is then expected to develop about the WA border and may extend a trough into far west SA late on Sunday.
