Weather Situation
A trough spanning from the west and into the Gulfs will move inland through Sunday evening. Following this a low pressure system will move into the Bight by Tuesday bring a strong cold front with its passing. As the low moves off the Lower South East Coast Wednesday morning, the associated front will exit eastern waters and continue through Bass Strait. In the wake of this front a high pressure system will move into the Bight, passing over central coasts late Thursday.
