Weather Situation
A high pressure system south of the Bight is maintaining a ridge over Tasmania over the weekend. A warmer northwesterly airstream is then expected to develop during Monday as the ridge gradually moves to the east and a cold front approaches from the west. The cold front is expected to move over Tasmania on Tuesday resulting in a return to cooler southwesterly flow. Another high pressure system approaches from the west on Wednesday.
