A good point has been raised of this current heatwave so I have been looking at some historical records.
January 1939 ConditionsAfter the fires and heat of January 1939, I found an old front page newspaper article dated 16 February 1939 that indicates that heavy rain fell over Victoria on that day, 16 February 1939. That can be found at:-
http://www.abc.net.au/blackfriday/timeline/html_tl_1939_32.htmYou need to scroll to 1939 and then scroll along the headings to find the various storeys and weather conditions during this period.
I also found at another web site via Victoria Department of Natural Resources and Environment that indicates the weather for Melbourne leading up to the Black Friday conditions. It states Melbourne had:-
43.1C on 8/1/1939.
44.7C on 10/1/1939.
Melbourne experienced milder conditions on the 11 and 12 then Black Friday when it reached 45.6C on 13/1/1939. That is the highest official temperature for Melbourne.
It came ahead of a cold front that brought no rain but a cooler change. However the state suffered that bushfire outbreak with the worst being east and north east of Melbourne.
There was a general heatwave during the period 6 to 13 January 1939 but big rains came one month later.
1983 - The heat and drought of January and February did start to break in March 1983 with general rains around the middle of the month. Living in Albury at the time, I do remember early March being very hot and still remember 3 days of rain in a row around the middle of the month across much of the state. Thereafter, the drought broke after good rains returned.
There is a known history of the state experiencing heatwaves like this followed by big rains a little later on. This is something to watch.

From
http://www.bom.gov.au/announcements/media_releases/vic/20090130.shtmlMelbourne sets heatwave record 30/1/2009Hightlights that Melbourne has endured 3 days of above 43C for the first time in recorded history.
It also highlights Melbourne's longest heatwave being 15 to 20 January 1908. That has not been broken.
However, the highest temperature of 13/1/1939 being 45.6C has also not been broken. It reached 43.4C on 28/1/09, 44.3C on 29/1/09 and 45.1C at 4.27 pm on 30/1/09.
Note:- The article mentions 44.2C at 2.27 pm 30/1/09 but it did reach 45.1C 2 hours later. A cool change immediately after 4.27 pm dropped the temperature to 37.1C at 4.35 pm (Weather Observation for the Melbourne Area, 4.35 pm Bureau of Meteorology 30/1/2009)
Other maximum temperatures for Melbourne include 44.2C at Melbourne Airport, 45C at Avalon, 44.4C at Essendon Airport, 44.8C at Laverton and 44C at Viewbank.
Across Victoria, very high temperatures prevailed again for 30/1/09. These are the 3 pm readings including:-
45C at Kerang
44C at Hopetoun, Ouyen, Swan Hill and Walpeup.
43C at East Sale, Echuca, Edenhope Airport, Kanagulk, Nhill, Warracknabeal.
42C at Benalla, Mt Gellibrand AWS and Yarrawonga.
Many centres had 40 to 43C for the third consecutive day in a row.
(Daily Weather Bulletin for 3pm, Bureau of Meteorology, 30/1/2009)
At the same time, a large dangerous bushfire continues to burn near Branxholme in these conditions.
Additionally in South West New South Wales, just about all towns and cities reached 40C such as 42.7C at Albury (3rd day in a row of such temperatures). Other 3pm figures include 43C at Balranald, Hay and Ivanhoe.
