Good morning everyone
Bleak is a good word for this morning - 0630hrs. Barometer dropped from
1010 to 997 overnight. Wind is currently light - around 5 knots and from
SSW. Sky o'cast with more rain clouds coming across. Several squalls last
evening from same direction, but with wind gusts estimated at around 20+
knots, that is) . Rain guage registered 45mm (24 hrs), but due to housing
density and block size is not in best position, therefore not accurate.
Probably resisters on the light side. Shame about the cricket :-(
Cheers,
Nandina

Well, the winds have woken and the squalls are coming through. The light
breeze I reported just over an hour ago has moved to WSW and is now gusting
periodically with light rain showers accompanying it. Wind strength during
squalls hard to estimate - perhaps up to 25 knots. And the sky to the south
is flat and grey.
Cheers,

hey all,
i was in grafton when we had that rather large rainfall. it was pretty much
all over night. was very heavy and did not stop. i didn't know that gold
coast copped it just as much. the window at my computer here looks like it
was open. my computer, scanner, printer and monitor got rained on. am very
surprised its still working properly! PHEWW! i noticed some of the damage
that that storm did a week or two ago. a fair few trees lying on the ground
along the highway.

Some interesting obs from east Bass Strait this morning -- more than
interesting if you're in a yacht.
Wilson's Prom's obs at 6am EST were wind WSW average 71 knots gusting
81, bar 983.9, a 3 hour fall of 8.0hPa! Wx was heavy showers (8mm in
past 3 hours) with vis 500 metres
At 9am EST wind had ***risen*** to WSW average 79 gusting 92 knots
(i.e. 170km/h), and bar had risen 2.2hPa to 984.9. (Yes, they don't
add up -- the reported bar is from an accurate instrument (mercury or
electronic), while the tendency and change is read off the barograph.)
The Bureau analysed a low of 982hPa off Wilsons at 6am. The US model
had picked this up very well for a few days before dropping it
yesterday, at which time the GASP and Euro models picked it up before
the US again fell back into line.
I'll be writing this event up this in my News section later this
afternoon -- there were some good wind gusts and point rainfalls
yesterday across Vic, southern NSW and Tas.
It's good to be back (i..e having email access, etc.) -- hope you all
had a good Christmas.

Reports on ABC radio that the cool change has brought summer snow falls to
the higher parts of the Snowy Mtns and the Victorian Alps. I also noticed
my barometer had dropped to 993Hpa before the change arrived. Late
yesterday I noticed a large storm probably located north of Dubbo and
moving roughly NE on GMS-5 IR satpics. There were some other smaller
cells in a NNW to SSE line to the SW of it, probably in location with the
surface front. There was some brief lightning and thunder hear in Ryde
along with a few spots of rain but not much else. - Paul G.

For those who already know, ignore this message. The lifted index is a
fairly reliable index which indicates the stability of the atmosphere. It
has to be approached with caution of course. A lifted index of -3 or below
is usually an indicator of possible severe weather. Below -6 and you are in
for it in real time. Try it and see what you think in terms of where
thunderstorms develop at that time. One of the reasons why storms may not
develop exactly in a particular region with a very negative value is lack of
moisture. So it is not fool proof but I have found it to be very reliable.
To obtain and plot the Lifted Index, follow the steps
1) http://wesley.wwb.noaa.gov/cgi-bin/disp_mrf.sh select the most up to
date time for the model data
2) On the next page, select LIFTX as the variable closer to the top
3) Then below, select aust for Australia,
then the time and date you want within the 3 day limit you have chosen
you can vary the countour interval you want (the default means automatic
but it usually plots at a comtour interval of 3)
4) Press plot and you should get the map (this is where the 4 page URL comes
from)
5) Please save these instructions. If you have any problems, e-mail directly

Storm Chase - Cebtral tablelands 26th December 1998
The chasers on this chase were David Croan, Matt Smith and myself Jimmy
Deguara
We had planned this particular chase earlier in the week and had decided to
head out in these areas based on the fact that the air was expected to be
very unstable with lifted index typically -4 to -6. We were uneasy about the
fact we had no data to indicate the amount of moisture in the air. Despite
this we headed around 10:30am and arrived in Lithgow by 12pm. We were
greeted with an already explosive atmosphere. From a very good lookout, we
observed and photographed very large cumulus developing rapidly to our SW.
It was very warm. Thinking it was developing near Bathurst, we headed out
towards it. (Rule number 1, get your bearings right. This is what I think
was the main reason we had a "bust" chase).
As it turned out the storm cells were developing to the S of Bathurst. I
also believe that some cells which had developed very near Bathurst
dissipated or lost their intensity. We were expecting the cells to further
develop. One cell in particular intensified and within the next 15 minutes
began precipitating. Other cells either became part of this system or
dissipated. By the time we arrived at Bathurst, it had developed into a
reasonably good storm.
After lunch in Bathurst, we looked for an internet cafe or library or
whatever which could give us access to the current satellite imagery and
weather situation. Unfortunately it was Boxing Day and evrything remained
shut. We had to go without. So we headed for a good vantage point on the
outskirts of Bathurst and observed a very large storm in the direction of
Cowra but further and other cumulus developing around the Cowra region.
Winds were northerly to northeasterly in Bathurst.
So as to keep us entertained, we headed for Cowra. This takes an hour os so
and to me seemed to take for ever. Just before Cowra, cumulus were
developing and the altostratus band observed earlier was dissipating. Some
quite fresh to strong winds occurred in this region. It seems this was an
area of convergence between the more humid N-NE winds and drier NW winds.
Behind this cloud region, we could see a band of thunderstorms aligned in an
approximate N-S line. This was the line with the change. After stopping for
a while, we oberved the area of cumulus which we had passed through
beginning to develop. By the time we had gone to a vantage point and decided
from what Paul Graham on the phone was saying, we decided to give chase to
these cumulus, some which has developed into thunderstorms although not
major. On the way, we received confirmation from Terry Bishop that a storm
had passed through Orange and was heading generally east towards Bathurst.
We could see the storms but by golly, we could not catch up to it. To add
insult to injury the back end of these cumulus which we were catching were
dissipating. This is when I knew it was all over.
We received another call from Paul Graham on the way to Lithgow that a major
storm had developed near Dubbo. Decision time again. Should we head north to
be in a better position for storms in that area. Or do we go home?
We decided to head north toward Mudgee. We had nothing to lose. At least if
this one worked out, we could take home the prize. The band of storms had
been moving rapidly east and we passed north of our closest cell. Just a
half hour before Mudgee, I called a stop through a clearing. The cell looked
weak and the cell Paul Graham was talking about was located to our NW. At
least 150km away! It had a spectacular back sheared anvil but looked as
though it was weakening. We could see cumulus to our west which were not in
a hurry to develop so we headed for home.
On the way south back to Lithgow, we were treated to a reasonably
spectacular display of lightning. There had been some areas of brief heavy
rain and the rear end of this storm looked quite impressive in the faiding
light. One of the highlights of the evening is that David (I'm glad he has a
good sense of humour!) did not have any water left in the water reservior
for the windscreen jet. But being a scientist, he decided to experiment.
Aim: what would it be like if I put the windscreen wipers on? What would
happen to the 1000 splattered mothes and mosquities. We will now take a
commercial break!
After more than 700 agonisong kilometres of fruitless or distant activity,
we were on the way home.
Reasons why we were not able to get storms on the day:
-unfortunate decisions
-no up to date data (Boxing Day holiday)
-the slow moving trough line and cold front accelerated during the evening.
-we should have chased around Lithgow where the NE winds would have
interacted with 3 storms or we should have headed straight for Dubbo and we
would have been treated to a very large storm
-we must also note that we are discovering new territory, and a different
climate than what we are used to along the coast. The air in the country is
usually quite dry and can make storms more concentrated and isolated.
My thoughts
I think when doing chases like this, it is worthwhile establishing
beforehand whether you will chase and be prepared to stay overnight or chase
more locally within the limits of about 200km to get home easily.
I would like to thank Matt and David for their patience and especially David
for his good driving and good sense of humour. Storm chases in the future
will become more and more successful as we get a grip of the types of
conditions the various regions in the country can offer.

My expected wind swing to the S/SW has not occurred ( hence my earlier brave
prediction of a late shower ), winds have stayed bone dry west all day, and
quite strong, some 30knot plus gusts.
I noticed that a bushfire has sprung up towards the NW, it looked as though
it may have been getting large at one stage, but the smoke seems to have
died a bit over the last hour or so.

I noticed this bushfire smoke on the way into Sydney from the F3 this
afternoon. It looked like it was to the SW but it was hard to say for
sure. I heard on the radio this morning that a fire ban was in force for
this region because of the strong, dry westerlies and summer
temperatures... Probably it was deliberately lit...

Hi Jimmy Deguara here from Schofields
There has for some time been global model data available which I have known
about but have not had the time to deal with.
For those with fast connections and with servers, there is meteorological
data available which can be plotted with the grads software package. There
are literally many variables which could be plotted. I'm not sure which
models would have the CAPE data or all of them do, but I know that some
people have used the Grads software to plot this data. The Cola site from
which the Total Totals index plots come are plotted using this data source.
One of the models are used. The data is available much earlier than the
plots.
The directions and software etc is available at
http://grads.iges.org/grads/ncepdata.html
Please note that some of the files are 20mbyes although most are smaller. If
anyone is able to host such information and plot certain variables,
pleasee-mail me. Anyone also willing to do the work in researching how to
plot the data using the Grads software, please e-mail me. I think this is
our only chance of having forecast CAPE for Australia. There is none
available that I am aware of. Yet the data is available.
I simply do not have time as I am doing so much at the moment related to the
society and the Australian Severe Weather site. It would be greatly
appreciated if we could get someone or a group to do the above. This will be
of benefit to all.

Sasan,
Hi,
What part (Roughly) in Sydney r u.
I'm at Hurstville and work at Parramatta. That gives me a good very to the
south and south west.
However, I can not get info on storms to the north.
Maybe we could help each other.

Hi all,
Well, the models indicated a nice surface trough coming through Brisbane
today, as well as LI's between -3 and -6. I had a DP ranging between 21
and 22C all day, and my temperature peaked at 34.2C at around 2pm.
Yesterday, a nice little row of storms had developed to the west of the
western downs. But disapated as they passed over the downs. I was
excited as it's normally a good sign. When I woke up this morning at
7:30am it was as clear as a bell, except for some Altocumulus
Castellatus to my ENE/NE. Not much though, just a little, but it put my
hopes up! Unfortunately the soundings weren't so kind, with a large
capping in the lower levels. Cu remained capped all day, occassionally
one would rise slightly above the others but then quickly went down
again...rising my hopes before smashing them back down on a hard
concrete floor...
The pressure at the Brisbane AP fell to 999.5hPa, it's very rare for
Brisbane to receive such a low pressure unless there's a TC nearby. But
again - the dam cap!
I was wondering that maybe as the trough passed through, if it would cut
the cap down to size for possible storm development...then again maybe I
should just give up!
SDS sufferer Anthony, from Brisbane.

Hi Grant
Im in the Inner city around the Balmain area
Reason my view is pretty bad is that on the southern and western sides I
am on the slope of a hill with houses blocking views to south and west
until storms are almost on us But dont have a bad view to the north and
minimal also to the east
Work around the Marrickville area but once again very poor views of
anything coming in due to lots of large factory areas

Hi Jimmy and everyone - it was a fun chase, we made a few wrong decisions
on the way but I think the overall plan was good - after all we were
right in the middle of the svr advice region, just a lack of low level
moisture away from the coast stopped more widespread activity. Also it
is just a pity we cant get readily access radar in the field as it would
really help in the decision making.
Anyway it looks as though we may be able to head a little north and west
perhaps on 29th-30th.
David.

The same server that does the LI plots can be used to plot previous
variables such as the CAPE values. This is good to see what the values were
in a certain location where storms occurred. Unfortunately, Darwin has so
high CAPE values it made other areas insignificant. Until tonight, I have
not bothered plotting CAPE values for this reason. However, a light has
shone upon me and I now worked out how to cutomise the maps so that you can
choose areas that you want. Below is the cape values mapped for NSW. You
will see that Eastern NSW has the most significant CAPE although most of the
high CAPE values are in the north of the state. I will look for a day when
we had very severe storms to give you a better example. (The data is
archived for about 2 months!!!) I will try to map the tornado days...

Hi all from warm Brisbane
Well I was up early hoping to chase and there never was a time that storms
looked likely. Shallow cumuli developed in all the right spots but they
were obviously capped. Also, dry gusty SW winds came through after during
the early afternoon raising the cap even more and really just stuffing
everything up. Storms with initial warnings did develop over the Capricorn
District (Central Qld Coastal and inland parts) and weakish activity
occurred in the Wide Bay district also.
Now to temps: (max, min, humidity%) Brisbane and Cape Moreton had the
seabreeze all afternoon, while some areas including Ipswich (Amberley) had
dry SW or WSW winds during the afternoon:
POINT LOOKOUT 29 24 80
BRISBANE AP 33 21 63
LOGAN CITY 35 21 55
REDCLIFFE 36 23
MAROOCHYDORE 37 21 70
NAMBOUR 38 22 35
TEWANTIN 38 23 50
ARCHERFIELD 38 21 48
AMBERLEY 40 19 23
