on Monday. A low pressure trough over western Victoria will remain slow moving
on Monday before moving slowly eastwards on Tuesday crossing central districts
by the afternoon the stalling over the northeast Tuesday night. The low
pressure trough will persist over eastern Victoria on Wednesday while a narrow
high pressure ridge extends across Tasmania. The low pressure trough will
deepen over eastern Victoria on Thursday as a cold front approaches from the
west.
