It was 1.5 degrees at 5:30am this morning in Blackheath. (Wednesday)
I wonder if we had any wet snow during the night. It might have been
just cold enough earlier this morning. Oberon must have been a
possibility for it.

Hi all,
There was a small article in the paper today(The Courier Mail), with a
photo of the damage. I scanned it and put it online, it's a fairly
large image (~300k) - had to try and keep the quality up, and also make
the writing large enough to read.
http://www.bsch.simplenet.com/anthony/newspaper.jpg
They actually called it a 'tornado' (wow!), instead of a
'mini-tornado.' They have a photo of the worse damage, although with
the family in the background. I personally am rather upset at this,
when Ben and I went to look at the damage, I could tell they were very
distraught, and we tried to be very quick, hence I didn't interview them
on what they saw etc. Yet some one from the media waltzes in, and wants
a photo with them to sit in front of the damage!!!
(Groap/Groan/Gripe/Whinge)
Anyway, this will give you a quick idea on the damage.

Has anyone else noticed that since about 18:00 GMT on 03/11/1999,
the site http://www.npmoc.navy.mil/ has exhibited extremely slow
access rates from Australia or even elsewhere for that matter.
The ASWA archive logs show that download rates have dropped from
an average of 12Kbytes/s to consistently less than 1Kbyte/s. As
the ASWA archive for gmsc and gmsd downloads the "latest" image
only, completion times have been 10-30 minutes later making it
possible that a new image becomes active at the site while the
old image is still being downloaded. This causes corrupted images
within the gmsc and gmsd satpic archives. With gmsfull, I have
initiated a "mirror" type of archive program using the NPMOC
jtwc archive. This has proved to be robust, however, since
03/11/1999, the number of reattempts due to connection timeout
errors is up to 10 times. There has been no degradation of
download rates within Australia over the same period making
the hunt for a local source of high-resolution "free" GMS5
satpic images more important. As a hunch, I know that a new
geostationary satellite is being tested, namely "MTSAT", and
that this testing may well be increasing the load of processing
at receiving/processing stations, including NPMOC and others.

Even worse, Channel 9 had no idea. At 6:00pm it was a "mini-tornado" while
on the 11:00pm lateline show it was "cyclonic winds". I reckon ASWA should
have a standard letter advising of incorrect terminology that is sent to the
general manager of the offending network/news media whenever we hear/read
this.

Yep I am getting the photos scanned this week - should be online by this
weekend hopefully. Oakhurst is a sparsely populated estate on the
north-western fringe of town (Maryborough), so I highly doubt anyone would
have taken a photo, let alone have the time to grab their camera by the way
some of the eyewitness reports sounded.
By Saturday I should have most of the related newspaper articles online as
well (from Nov 29 1992), I will let the list know once they are all up.

In the midst of scouring old monthly weather summaries, I found a
reference to what sounds like an exceptional hailstorm at Leigh
Creek, in northern SA, on 15 July 1971. The report stated that
hailstones reached up to 3 inches in diameter (which puts them in
the 7-8 centimetre range). Interesting, especially for a storm in
mid-winter (and a reasonably cold winter at that).

I phoned Jeff C up this morning (head of QLD severe wx) and reported my
findings to him, and we discussed the tornado. The reason who he said
it was not a traditional tornado, was because he thought it may have
actually been a coldie, rather than a warm-season supercellular tornado.
However, this is not quite concrete yet. Here's where it gets
interesting, the actual tornado reported, occurred in what appeared to
be a rain band with isolated t'storms. BUT - the actual rain band
itself, was formed by a dissipating supercel! To quote Jeff, it was a
"huge supercell" - with intense echos 50% higher than the normal 'severe
threshold criteria' (typically echoes of 45dbz over 8km/27,000ft are a
good indication that a t'storm is probably severe, this cell had echoes
of 45dbz up to 12km/40,000ft) - and that was from Marburg radar, about
300km/190miles away! This cell was situated between Gayndah and Gympie,
and caused a real mess between Gympie and Goomeri, apparently some one
reported the highway between Gympie and Goomeri to be "impossible to
travel through without a chainsaw" as it was covered with trees and
branches.
To add more fuel to the fire, as mentioned in my earlier email, a funnel
cloud was reported in Gympie. Now, could this have meant that a tornado
was present in the supercell before, and still continued as this
particular cell weakened? IE - I have heard of reports in the US when
a t'storm of 60,000ft have spawned a tornado, and the tornado was still
present even when the t'storm had weakened substantially to about
35,000ft. Given this scenario, one could say it would be possible for
the funnel to continue to skip along its path (as many do). It would
not have been hard to miss Gympie, Gympie is not very big. Furthermore,
it would not be very difficult for a tornado not to be spotted, or even
the damage path of a tornado! The area around Gympie is VERY hilly, and
full of trees/shrub/fields. Despite the incredible storms they get in
Gympie, it would be a storm chasers' nightmare. I have to laugh as they
have the speed limit of 100km/h in most areas around there, and I can
tell you that you're flat out doing 40km/h around some of those bends on
the mountains/hills. It is a little hot spot though, I was telling Ben
yesterday how interesting it was that Cedar Pocket is near the town of
Kin Kin - and Jeff C also mentioned this - that the town of Kin Kin has
almost been wiped off the map a couple of times in its history. So it
is a little 'hot spot' - and as David Croan mentioned earlier, high
CAPE's are quite frequent there, with DP's often up to 1-2C higher then
they are in Brisbane. The same goes for temps.
So - I guess the main debate is was it a coldie, or a warm-season
supercell tornado (keeping in mind that a TC spawned tornado works in a
similar way to a coldie). Conditions were favourable for coldies on
Monday.

Woops - I missed that, just saw the title and I guess I was in so much
shock that the title didn't consist of 'mini-tornado' that I became
complacent while reading.

A few months ago, 12 hourly became 6 hourly. A few weeks ago,
colourised versions of the wind shear map became available, and also a
change of wind shear over 24 hours map. From today, you can zoom in a
fixed amount on any map -- bad news for the Tasmanians, who get the
chop, but quite detailed pix for the rest of us. The Vis pic, which
used to be confined to the tropics, now covers the same near-sector
d/c area as the other frames.

Yes, Michael -- I automatically download the gmsd panel, but I'm going
to have to stop doing so. In addition to very slow download, which
holds up other things on my system, there have been several occasions
during the past 6 weeks or so when my computer has downloaded rubbish
files in the range of 15 to 35 *megabytes* rather than the usual
satpic of ~300k. Even on my ISDN line, such downloads can take hours
depending on other traffic. This may also be related to the file
changing at the other end during download.

Between 1 and 1.45pm we've had three separate wintry showers of heavy
rain and sago to pea-sized hail. Definitely no thunder this time.
Large Cu have been around all morning, but didn't look high enough to
generate much. It's obviiously still pretty cold upstairs -- here's
the latest ACARS data -- freezing level around 5400 feet, and only
5.2C in the free atmosphere at Blackheath's altitude. There's a note
on how to read the data at the bottom.

Hey Ben from Brisbane here..
I heard on the radio this morning that flooding around the Warwick area
from the rain over the past few days has caused over 1 million dollars
in damage to the road network.. while there hasn't really been any huge
falls out there (a couple of 100mm's and a stack of 30-50mm's +).. it
just has to fall in the right places, or over a wide area and it adds up
to a huge amount of water for the river systems to handle..
The Macintyre (think it's the Macintryre) river is expected to peak at
over 7m's in Goondoowindi (SW of Brisbane) tomorrow morning causing
moderate flooding.. if that was a bit higher i would be out there
snapping some pics - i'm a big fan of flooding..

Second that, definately no thunder this time. For the second and third
falls, I was at the Govetts Leap lookout, it fell quite heavily there
for a short period. The air was quite dry too, relatively speaking,
around sixty per cent I think.

We in the UK get "coldies" - presumably this is an ozzie term for tornadoes spawned
by cold fronts or single cells in deep cold air. There is no distinction between
coldie tornadoes and tornadoes spawned by supercells, except perhaps the way that
they've been formed - they both cause damage!
Supercellular tornadoes can last longer but thats the only distinction IMHO.
Talking to Matt Smith this morning - he was saying that your government is playing
down tornadoes this year as they don't want to scare away the tourists for the
millenium, olympics, etc..... here's your chance to do a form of eco-tourism in the
guise of "ASWA Storm Chase Tours" in the same way as Cloud 9 or Silver Lining in
Oklahoma (:
