Weather Situation
A high pressure system over the Tasman Sea extends a ridge across the state today, directing an onshore airstream, while a trough enters the South Coast on Wednesday and moves north, reaching Sydney later. Behind this, a strong cold front should cross the coastal waters during the weekend, driving fresh and gusty southerly winds, and may deepen to a coastal trough in its wake early next week.
