Weather Situation

A high pressure system over the central Tasman Sea will drift further eastwards on Monday. A low pressure trough over western Victoria will remain slow moving on Monday before extending down into western Bass Strait early Tuesday then moving slowly eastwards over central parts of the strait during the day and the east on Tuesday night. The trough will contract inland to sit over northeastern Victoria on Wednesday while a narrow high pressure ridge extends across Tasmania. The low pressure trough will deepen over eastern Victoria on Thursday, Christmas Day, as a cold front approaches from the west, reaching western Bass Strait by the afternoon. The two systems should interact to produce a low pressure system just east of Bass Strait on the morning of Boxing day.
