Yes the temp is quite warm. We hit at least 35C out here in the Western
Suburbs. It has been like this for at least 4 days now......

We need storms as all chasers from Victoria and New South Wales and
Queensland are planning to chase. No storms make it difficult.....

The Australian record high temperature for September was
equalled on Tuesday, at Mandora in north-western WA, with
an obs of 42.8 C. This took a few days to come to light 
because there was no report at 0900 the following morning
(although there was at 1500 the previous day) - it has now
been checked with the observer.

The equalled record was originally set at Wave Hill (NT) on
10 September 1933.

A list of Australian and state extremes for each month may
be found at 

http://mullara.met.unimelb.edu.au:8080/home/blair/extremes/
staterecord.html

(I am about to re-run these to take into account some pre-1957
WA data that has recently been digitised, but this doesn't affect
the September record).

I think impossible is the appropriate term !

I am getting that stir crazy I would chase a rain shower at present. I
personally do not hold big hope for Saturday, although something that you
may find interesting is that a very weak SE wind change has just arrived
here at Shellharbour ( 8pm )  ! it may be enough to push the lower
atmosphere into action tomorrow, I doubt even that the change will reach
Sydney.

Tuesday onwards next week looks interesting, I think positioning one self on
the northern margins of the cloud may provide storms, especially as it moves
NE.

Regards
Michael

This image is definitely worth having a look at - the ITC is clear as a bell
as is the frontal boundary of the system moving through at the moment.
