Weather Situation
A high pressure system south of Western Australia extends a ridge over South Australia. The tail end of a cold front will brush the southeast corner of SA tonight. The high is forecast to move east on Friday to be southeast of Tasmania by Sunday allowing another weak front to brush over coastal parts of SA Sunday night and Monday. Another high pressure system is expected to follow early next week.
