The GMS-5 water vapour imagery for this afternoon (30/1) shows the
very spectacular thunderstorm development along the trough over
central-northern NSW, where the guys were chasing. Several storms at
UTC 4:25 have impressive V-notches - wouldn't be surprised if there
were supercells among this lot. A lot of large cells also popped up in
the next image 37 minutes later.
I have downloaded most of them (unfortunately not the UTC 6-7) so they
can be animated later.

Thanx, Blair, I feel so much less gauche now.
Nandina here - I have 2 questions which somone might like to answer for me.
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.
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

Jimmy - a moment of trivia.
Nandina here
In my experience, whenever a 'decision' is called for - especially a hard one, then it is going to appear 'unfair' to someone.. That's the nature of decisions. :-)

Nandina here -
Michael - just take a look at the amount of technical stuff we have included this morning. Great stuff.
Because I'm an ex-chalkie, and because you brought it up, I checked the dictionary. It says 'fulminate'. It is a verb but also has a noun meaning:- the salt of fulminic acid. The fulminates, chiefly mercury and silver are very unstable compounds and explode with great violence by percussion or heating!!
Further, the the origin of the word is from the Latin, fulminare, which means flash like lightning.

thanx David - yep, I checked that in the dictionary too - and as you said. It's a tube formed by lightning. - or a rocky substance that has been fused or vitrified by lightning. That certainly sounds more accurate than my earlier definition. G'donya!

Very heavy rain experienced here this morning. So far 60.2mm since 4am this
morning. Takes monthly total now to over 200mm, which is I think the 5th

Meeting of ASWA on the 9.1.99 at the 2ky Building, Parramatta.
Meeting opened: 10.20am
Present: Darren Hayes, Michael Bath, Matthew Piper, Matthew Smith, Michael
Scollay, Jimmy Deguara, Paul Graham, Paul Wickham, Grant Boyden, david
Croan, Geoff Thurtell, Michael Thompson, Paul Mossman.
Business Arising:
* Paul M: Nothing heard from dept Fair Trading re: Incorporation.
* Michael Scollay: Bank account information. Presented the meeting with a
number of options regarding opening a bank account. Seems that Westpac is
the better option, as it may have an account specially set up for
incorporated Associations without fee attachments like other accounts. Moved
& carried that the account be in the name of the Association. Also moved
that Michael S approach Westpac regarding the "fee-less" account.
* Paul Graham: Communication between chase vehicles. Many options were
discussed including, UHF, "walkie-talkies", VHF and radio. Anyone interested
e-mail Paul G as he has a variety of plans & options. It was suggested that
UHF would be better as less interference from lightning etc. Paul G will
invite someone to the next meeting to present some information on the
application, running of & use of these type of radios.
* Everyone: Communication of severe thunderstorm advices. It was totally
agreed that the frequency of these warnings is inadequate (on behalf of the
media). Suggested that approaches be made to TV & radio networks regarding
these.
* The Internet site is the capable hands of Michael Fewings. Paul M to
contact Michael regarding what is happening.
* ASWA Logo: Matt Piper asked to put some colour into these logos, then
there will be a vote. Paul M will then approach a shirt logo place and bring
to meeting when a logo is decided upon.
* The mention of shirts included in membership was mentioned. It was decided
that a subsidised shirt be available to members at a cost of $10. Moved &
carried.
* Membership: Decided that membership would include Meetings, storm news,
T-Shirt (subsidised), web based radar.
Then a great display of pics completed a great meeting.
Next meeting 13.2.99 at 2ky Building in Parramatta.

The 12z mesoLAPs is showing a bullseye of strong middle level uplift
centred between Moree and Walgett for 12z tonight, while GASP for the
same time is showing a large area of northern inland NSW and SE Qld
getting >50mm in the 24 hours to 12z tonight, with parts of N NSW
getting >100mm. GASP then shifts the area of heavy rain *very* slowly
NE, with falls to a similar level over a smaller area around the
NSW/Qld border on the slopes and tablelands in the next 24 hours.
Neither the MRF 00z from yesterday or the 12z overnight AVN are quite
that enthusiastic, but still have bullseyes of >25mm over the same
area, so all models are obviously picking up major rain-producing
mechanisms. GASP has a tot-tots >60 over central northern NSW at 12z
tonight! I haven't checked out the US model lifted indexes.
The mechanism producing this amount of rain seems to be strong
moisture advection around the southern end of the trough through
central/western Qld + cyclonic curvature + increasing low/mid level
convection. I notice the Qld forecasts are going for mod/heavy falls
in the SE. The NSW forecast notes simply refer to the ubiquitous
"upper disturbance" over inland N NSW.
Given the unanimity of the models, I'd say there will be some
interesting developments in the region.

Last night's AVN run supports NOGAPS in developing a cyclone off the
WA NW coast midweek, though both keep it offshore. GASP at this stage
is having none of it, preferring to develop a massive trough down
through western WA which, with a strong high ridging in from the west,
would make it pretty blowy midweek. It'll be interesting to keep an
eye on this mornings models.

Hi All,
Melbourne has been quiet now for all of two full days and now another
trough looks to be working it's way into significance by Tuesday for
Western Districts (Paul Yole) and for all districts Wed/Thurs/Fri so we
have to catch up on our sleep now for the coming action.
Can't wait for the report from the NSW boys from yesterday.
Goodluck to anyone else who chases and to Bodie (he knows why).

Hi every1,
I've finally had time to write a report for the Donald-Charlton storms
earlier this month.
It's an experiment in that I didn't have any decent photos or any decent
graphics but I thought I'd try to at least flesh out a report.
I'm mainly interested in:
* whether I've included all the information that people want;
* whether the page takes too long to load;
* and whether it's worth the effort to post chases like this (which I
consider a bust - even though my video has some good stuff) especially
if it don't have no spectacular photos.
Hoping I haven't wasted anyone's time,
Kevin from Wycheproof.

Hi there all.
The Energex lightning detector is going off at the moment, 143 strikes
in the past 5 mins (at about 9.50pm) centred mainly to the west of Oakey
and over Dalby. Should be putting on a good show for the QLD contingent
if they're watching.
There is a Severe Thunderstorm advice out for the NSW east of a line
from Wanaaring to Balranald and west of a line from Tocumwal to
Inverell.
There was some promising development to the north of Melbourne this
afternoon which I wasn't expecting. They developed and dissappated very
quickly though.
The forecast for the week is looking like it has for the past fortnight
with the winds coming out of the NE for tommorow, raising the humidity
levels. Where is the jet stream strongest at the moment?
Looks as though the NSW guys had a good chase according to the updates
from Jane. I look forward to reading all about it in the next couple of
days.
Jimmy, have you heard anything more about that Ballarat funnel? For
instance, did it touch down or was it just a lowering?
I think I'll go to sleep now as it looks as though we could be in for a
busy few days down here. I've only just caught up on the sleep I missed
at the end of last week.
Happy chasing to all
Chris

Hi Kevin
Sort of the same. LAPS (Limited Area Prediction System) is run twice
daily by the Bureau for the Australian Region (compared to GASP which
is global). LAPS has a horizontal grid spacing of 0.75 degrees (i.e.
3/4 of a degree of lat/long). The mesoLAPS is a higher resolution
model nested within LAPS with a grid spacing of 0.25 degrees, so it
picks up shorter wavelength features, or more detail. It's actually
two nested models, one for SE and one for SW Australia.
There's more information (but not much) about it at
http://www.bom.gov.au/reguser/by_prod/nwc/ab_nmc.shtml
How do you get it? Pay $$$ (600 a year) to the Bureau for their full
suite of charts. Sad, but true.
