Weather Situation
A high pressure system east of SA extends a ridge across much of the state, as a low pressure trough over the interior of WA weakens overnight. Another trough will approach from the west late on Saturday, move across SA on Sunday with a ridge then extending into the state from a high located southwest of WA. An upper level disturbance will move over the far west on Monday, and a cold front will slip across southern coasts later in the day and early Tuesday. The high will then move across waters to the south throughout the week.
