Hi guys.
How many people do we have going - I probably shouldn't take the car
too far as I lost the O ring for the sump and there has been a slow
oil leak. I guess we'll work something out- any ideas.
Im on austnet weather now.

Hi All,
The highest unofficial rainfall so far is 46mm at both West Wyalong and
Cargo (a small town 50k's
West of Orange.)
We only managed 12mm in Orange. A short sharp storm. The local vineyards
don't want rain at the moment. The grapes are about ready for harvest.
At 07.45 22C, 1007, 46%, No Breeze. No sign of any cloud at the present time
for any chases.
Terry.

How do we get on ausnet. If we don't take your car we will have to cancel
as there will be too many. More than 3 in a car is too many and there are 5
going. I am taking my car...

Anthony,
63 mm at Bardon last night. Yes things were looking promising this
afternoon. I went up to Mt. Cootha for a look. As you said I thought a
warning was on the cards even dialled the 1300 number but nothing.
I could also hear thunder from here - at the time the lightning tracker
was indicating the cell to be the east of Ipswich.

Hi everyone,
Jimmy here. After some hard decisions (in some cases unfair), we have
decided to head north to the Hunter and see what happens. The target area
is the Liverpool ranges. First stop Singleton. Then we will head northwest
from there.
Please keep up up to date with radar and satpics etc.

HI Mandina. All lightning is either CC or CG. It only appears "sheet"
lightning when its behind a cloud or in dense precipitation so you can't see
the actual strokes of the forked lightning. If you know what I mean.
James from Brisbane
Second query. Is what the lay people refer to as Sheet Lightning really CC
lightning? And are both sheet and forked (CC and CG) lightning generated in
the same way, except in the target they seek? When I observe a real show of
"sheet" lightning there appears to be far more activity than in the event
CG lightning, and my memory suggests that the 2 are usually exclusive of
each other. Am I correct? Is the appearance of greater activity due to the
fact that CC lightning travels on and on - maybe turning around or coming
back on itself to find the next cloud? So that the one occurrence may appear
as a series of flashes, perhaps?
Oh, and thanks Michael - great to hear your reassurance.
Cheers,
Nandina

Good choice, I feel that you will need to get at least 300km north of
Sydney. The SE is now well established here.
Sorry for my stupid call on todays weather ( although I do think the
activity will be well north ) and letting my wife have the car for the day,
if I had the 4WD beast with its generous seating this may have eliminated
some of the ' unfair ' decisions, only guessing as I am trying to read in
between the lines.

I will tackle the lightning question first - as James mentioned there only
the two CG & CC. Sheet lightning is simply CC or CG that is hidden, in clear
air it can even be below the horizon, CC lighting tends to light things up
due to reflection from the cloud and the fact that it is up high for all to
see...
Dew point is a bit more tricky - nothing is simple and dew point cannot be
looked at in isolation as a factor or whether rain or storms will develop. A
classic example would be the Namib coast of the Kalahari desert in Southern
Africa, no problem with high dew points there on many days, probably at
degree or two below air temperature, yet it is a desert with rainfall lower
than most parts of any Australian desert. What I am trying to say is you can
have all the moisture in the world, but unless you have something to lift
it, it is useless. This is where my meagre knowledge runs short so if I am
wayward please somebody rescue me - to get storms you need both lifting and
mositure, much of the lifting occurs from heat ( relative ), higher heat
levels can in many circumstances lift even meagre amounts of moisture high
enough to form storms. Chasers in the USA that are more advanced in this
area can often calculate the surface temperture needed to get air parcels to
rise through a given atmosphere profile.
Michael
The first concerns Dew Point. Now I have discovered what Dew Point is and
how it is measured. What I have not yet discovered is how the Dew Point
reading relates to forecasting. I get the feeling it is not just an
observation.

During yesterdays storms in Melbourne a house in the northern suburg of
Epping was hit by lightning. A large hole was blown out of the roof of the
house causing debris to crash into the living room. Damage bill would be
many thousands of dollars. I was wondering why does lightning stike
buildings people ect and sometimes do little damage and at other times its
hits like a bomb. Any ideas anyone? Dane

Ok Dane I will have a go....and no doubt so will others.
Heres my theories:
1. The reason it may have "blown" a hole like that is because the lightning
supercharged the air in the roof cavity, causing it to expand very quickly
(thats how thunder is formed) ..this resulting expansion would cause the
roof to pop like a balloon?
OR
2. The discharge of the lightning bolt caused it. ( :-)
Whereas when it strikes people who are earthed properly, the discharge may
cause some entry & exit burns, as well as shortcircuit there nervous system,
thus causing heart attacks (since the heart is very dependant upon
electrical impulses to keep the heart beating in rhythm. - also commonly
known as arrhythmia when the heart doesn't beat properly & beats
irregularly.) People who are not earthed will also "explode" that is there
cells will frazzle, and their insides will "burn" because of the huge
voltage of electricity. I have seen a postmortem of a lightning victim,
whereby his insides were cooked literally....and every major organ
disintegrated to some extent. (hope no-one is eating.....)
Any other thoughts?

I am probably wrong but it depends on the resistance of what it strikes,
resistance = heat when electricity is passed through it.
Some trees conduct lightning down the outside of the bark, and if it is
dirty and wet the tree often survives unscathed. Other times it trys the
hard route down the wood, meets resistance, the sap expands and tree
literally explodes. Which gives me the opportunity to debunk a
myth.....lightning striking a car is conducted to ground very easily, forget
the stories about the tyres isolating the car, grimy, slimy wet tyres
conduct well. If the tyres insulated the your car, the irony is your car
may well get damaged.
Who has heard of a fulmarite ( spelling prob' incorrect ), I actually have
one. It occurs when lightning strikes are tree growing in sand, the
lightning is earthed down the tree roots, but meets resistance in the sand,
the silica than melts, then solidifies glass like around the tree root. I
found mine at the local Windang Beach sandhills, which in the 1970's were
bulldozed flat under the banner of ' soil conservation ' , one dune was 90m
high. But that is another story.

I think it has to do with how well it's earthed, I know that lightning
can destroy a small brick/concrete structure if it's no earthed,
possibly to do something with the resistance it gives against
electricity? Where as if it's earthed with a lightning rod, then the
metal allows it to travel safely and quickly to the ground with little
resistence.

Hi all
It looks like we'll get some goodies today, with the lightning tracker
already showing a good deal of activity over the Darling Downs. A nice TCU
just developed to the NW probably NE of Crows Nest and while its looking
pretty sick now, it does show the potential for today. I just hope the
anvil cirrus from the Darling Downs showers and storms doesn't suppress our
storm activity.
Some obs from Anthony's weather office (hehe)
32.1C...23C DP...1007hpa and steady - will drop shortly
Light northerly only at the moment.

Paul,
Sometime between 1.00 and 2.00pm eastern summer time - although I
can't remember seeing them much before 2.00pm. It makes it hard
if you are relying on them to work out where to drive several hundred
Km to the best action.
Good luck if you are going out this arvo.

Hi Nandina, Michael and everyone.
I can remember a documentary on fulgurites on a cable channel. It was
to do with a theory on lightning causing power outages by hitting
underground cables - so they triggered lightning strikes by firing
rockets attached to thin metal cables into electrically active regions
of storms. Sure enough nice fulgarites were found leading to the
cables. Anyway I found their web site with some nice pics of them for
anyone intersted:
http://coolrox.com/fulgurites/fulgurites.htm
I hope the guys chasing get onto something today as wherever the
maximum instability is up around there I think there will be some
pretty severe ones with the favourable wind profiles.

12.30pm and the guys are near Muscellbrook, heading for the Liverpool
ranges. They have just broken free of the coastal crud allied to the SE and
it has cleared and there is congestus starting to go up near the Liverpool
Ranges.
I have a feeling that things will fire in a big way for them,.

Things are now looking great for the guys, but Mr Thompson is stuck in Mt
Warrigal, the worlds least thunderstorm occurrence after Heard Island. Well
actually I did hear thunder last night, nothing worth turning the PC off

Hmm the air soundings people are not real good whatsoever, even Brisbane's
are not that good. Wonder whats going to happen.....................
Looks like the dreaded southerly is here now, and most of the low cloud has
scurried away...oh well. Hopefully we might get some good rain.

Reply-To: aussie-weather at world.std.com
Hi all, from another contented, Victorian storm-chaser.
By the time the Foxtel satpics came up for 3pm on Thurs, storms were
stating to form along the leading edge of the low-pressure trough which
had formed over western Victoria. Half an hour later my friend,
Gabrielle, and I were in the car heading for the W of the state. An
hour into the drive brought us within site of the line of storms which,
according to the BOM staff, extended from the far N to the far S of
Vic.. I had just been in contact with the Victorian gathering at Mt.
Dandenong, and was informed by Jane O'Neill that a funnel cloud had
reportedly been sighted in the vicinity... I didn't have to think too
hard about whether to stay nearby or not.... At this stage, about 7pm,
a very well defined shelf-cloud was apparent about 50-100km NW of our
position, in the Ballarat area, and along with the ominous darkness of
the precipitation curtain it had the makings of an impressive storm. As
it approached, however, the s-c seemed to lose some of its definition
and the cell seemed to be weakening. But before you could say "Oh no,
here we go again" a fresh cell seemed to be developing to the S of this
first one. The s-c had a more ragged appearance than the original one,
but was still very obvious. The time had come to get ourselves in the
best position for viewing and photographing so we drove E 15km to a
town called Wallace which afforded us a nice, cleared hill which was to
become our ringside seat.
As the storm drew closer the s-c looked great with a fair amount of scud
under the ragged leading-edge. Not that I am experienced in this regard,
but I did think the gust-front associated with this cell would pack more
of a punch than it did. When it finally came overhead a bit of a gust
blew up but I would estimate peak gusts as not much more than 60kmh.
But if the g-f was a bit of a letdown the lightning show that was to
follow most certainly was not! Within minutes of the s-c passing
overhead the CGs & CCs began to go off. As the rain picked up in
intensity and the storm's core drew closer, we were being peppered by
CGs. The lightning rates ranged between 40+/min down to several
strikes/min and I would estimate many of the strikes were within 1-2km
of our spot - some of the thunder-cracks were wild! Some of the CGs
looked like very strong discharges, so I am hoping that some good photos
result. The CGs hung around us for 1/2 to 1 hour before becoming less
frequent. The CCs, however, kept on coming on strong with many seeming
to emblazen the dark sky over a range of 360 degrees -- it was a mighty
spectacle. By now the rain had settled to a constant, if not very heavy,
rate and it appeared the storm was leaving us to the E.. I was
interested in having a bit of a look at the rear of the storm, but
instead of noticing anything which might relate to rotation merely
noticed an homogeneous layer of cloud in amongst the constant rain.
This storm may have been decribed as an HP cell, but in my humble
estimation most certainly was not a supercell (BTW, has anyone with
radar checked the action in this part of the state with the view to
observe any hook-echo etc?).
The original storm we spotted was possibly the one which had earlier hit
Horsham (~150 km NW Ballarat) and it too didn't sound all that severe,
either, with BOM reporting 40kt gusts. There has been talk, however,
that near Hamilton (~150km SW Ballarat) a cell was observed to rotate --
does anyone know anymore?
Here's hoping the NSW folk get something today at least as good.
Regards
Greg Browning

The guys are at Gunnedah, have scored at great storm with lowerings and a
possible funnel cloud. They don't really know yet if there is anything on

disappointed )
Can't really miss as the situation now has storms just about everywhere out
there, even surprise, surprise down to Mudgee and Parkes, of course the

If possible, is there anyone with radar who could give Michael B a

but nothing dominant - the GMS5 satpics, although showing the general
trend of the system, are a bit to outdated by the time they come out
for allowing the guys to go after promising cells.

Atmospheric moisture, dewpoint etc has been described as the meteorological
equivalent to absolute humbug.
There are at least five different measures of humidity:dewpoint,relative
humidity,absolute humidity,vapour pressure and mixing ratio. There may be more
but I just can't recall. I won't try to be smart by reciting definitions but I
think the mixing ratio is one of the ones most used by forecasters to predict
rainfall or at least measure instability. It all has to do with lapse rates etc.
Now I guess I've made everything even more involved,so I'll say no more....

All I can say about the rain on late Thnursday night was that there was
heavy rain at Toowong when I left work at about 10.30 pm ( Quite an

clothes sopping, glasses and windscreen fogging up ). Then driving down

I've been way out of things for the past couple of weeks due to work,
and I've just struggled through about 400 postings from the past week
or so to see what I've missed. Now I've a bit of spare time, it'll
probably get boring again.

How long are they up there for? The latest GASP and AVN both have
*very* heavy rain around Moree tomorrow (GASP goes for a peak of
75mm/24 hrs), moving only slowly NE on Monday and Tuesday with similar
24 hour totals around SE Qld. AVN has an area of lifted index <-6 over
southern Qld not far north of the border today moving gradually east
tomorrow.
Current radar shows there were two areas of storms around Moree around
7pm edst with spots of >100mm/hr reflectivity moving generally east,
but they've weakened and diffused since. There must be some good rain
NW of Bundaberg, cos there's a huge system there that is moving ever
so slowly NNW. There's also a big one off the coast SSE of Ballina
(lots of >100mm/hr) and another (sadly weakening rapidly) about 50km S
of Brisbane at 8.10pm edst
GASP has next trough of interest to those in SE Aust passing through
around Friday with some reasonable chance of TS, but that's a long way
out. NOGAPs, if it is to be believed, has a significant TC off the NW
WA coast by Thursday.

Michael said this evening that they'll pack it in and start back for Sydney
tomorrow morning - if there's a good reason for them to stay in that area,
early in the morning is probably a good time to let them know once we know
what the tomorrow's developments are.
The LI's for tomorrow aren't too exciting (0 - +3) - Laurier, does that mean
heavy rain being predicted by GASP rather than storms?

Hiya Folks,
After a drought of no storms for almost a month, we finally got one
tonight (30/1).I was watching it come up the coast, deciding whether or not
to go over to East Ballina to take some lightning shots.
After watching the sheet lightning for 5 mins, a massive CG lit up the sky.
I then hightailed it home to grab my camera & go over to East Ballina.
I counted at least 10-12 CG's as I was going over, all the while thinking
that I would get some great pics. As luck would have it, "Huey" didn't want
to play anymore & I only got 1 pic (AAAAGGGGHHHHHH)!!!!!!!!
The leading edge of the storm had a lot of scud but it was hard to tell if
it had an roll cloud (too dark, even with the CC's). Most of the storm was
out to sea, we got the western tip of it.
Rain started at 20:20, finished at 20:45 only 5.4mm strongest wind gust was
39 km/h. I was told that some houses in Evan's Head (35-40 km Sth) had some
damage.
I just wished the lightning was more co-oprative!!!!!!
See Ya's
John
