A high pressure system over the central Tasman Sea is maintaining a ridge into New South Wales, while a trough over South Australia draws closer. Rain associated with this system will reach the western border later today, and is expected to increase during Wednesday and Thursday as a low centre developing within the trough passes over the state. Another high is forecast to move in behind the trough during Friday as the low moves rapidly away to the east, and this high should remain the dominant feature in the region through the weekend.
