Explanatory Notes
A high pressure centre near Tasmania extends a ridge over eastern Victoria.
Both high and ridge will drift slowly east during Monday, directing a
northeasterly airflow over Victoria. The airflow tends more north to
northeasterly during Wednesday as a large low pressure complex builds south of
the Bight. An associated trough and cold front crosses Victoria during
Wednesday and early Thursday, bringing a burst of moisture-rich air to the
State that originates from the tropics. A cooler, drier west to northwesterly
airstream then establishes over the State later Thursday, tending west to
southwesterly on Friday as a ridge builds to the north and a cold front crosses
the southern parts.
