I am not able to chase today as my car is for sale on the first day
advertised. It is important I am here. Of course if there were a supercell.....
I believe, chasing down south Today around the Southern Tablelands or
Central Tablelands around Lithgow. You won't get severe storms but in the
clear conditions, you will see nice storms

It is looking great for Saturday at this stage. We will have to keep track
of what is going on whilst the meeting is on. And then we go to chase. To
the West of Sydney. it looks great but I will have to check the upper level
winds to see the most ideal chasing location.

I've seen three separate reports on this:
- the 0900 weather bulletin (251mm)
- the SA daily rainfall bulletin (51mm)
- the SA severe weather advice (which refers to 'more than 150')
The 3-hourly synoptic reports tend to back up the 51 figure (as does
the ~13mm from Mintabie, the nearest neighbouring station 30km to the
west), but we won't know for sure until the monthly return is in.
If the 251 turns out to be the correct one (unlikely, in my mind, but
possible) it would be close to the SA record.

The minimum at Mildura (to nearest degree) overnight was 31
degrees. The actual value to one decimal place will be somewhere
between 30.5 and 30.9 (the lowest synoptic observation). This may
well be a Victorian state record, depending on exactly what the
value comes in at: the existing record is 30.7 (also at Mildura on
2 January 1955).

Hi Jimmy here.
There are storms developing to the W on the mtns and to the SW and S of
Schofields (Sydney)
I am in particular interested in one near Mudgee and one to the far S near
the Shell harbour area. Quite resaobable heights attained by the storms.

Hi Dave,
You have got to be the most pessimistic chaser I know! Bustchase? :)
(Or does that refer to females?)
Yes, the updraughts were fairly good and widespread, I got photos of
duststorms as well and some isolated dust-devils undeneath the fringes
of Cbs!
I hope the film shows them well as I didn't have a zoom.
No reports (official or otherwise) of any damage, just the "blowing like
buggery" variety. I wouldn't have classified the storm as severe.
BTW do I need to fill out that Storm Report form I saw advertised here a
few weeks ago? It really was just a common or garden variety cell
(except for the weird updraughts)?

Hi Jimmy,
How do you tell the heights that a storm achieves?
I've seen the NEXRAD stuff on the US sites which show maximum cloud
heights (BTW I saw one listed as 70,000' last autumn in Oklahoma!), do
we have a comparable system here or do we use RHI radar?

Oops!
I meant ECHO heights, not cloud heights, and I suppose RHI is what
NEXRAD uses as well.

Hi all
1500: I just had a look at the local development from Beacon Hill
lookout which is on the northern beaches of Sydney. Broken line of
convection happening over the ranges running from NW to SSW. A cell to
the NW looked to be anviled out and was sheared strongly toward the
NE. Some new updrafts got going at the back of this cell (1515) and
these were also beginning to lean quite strongly so probably not
enough strength to overcome to upper level winds.
Another fairly solid looking updraft was attempting to fire to the far
SSW (Wollongong ish)? from my vantage. This did not look sheared (as
expected) due to the angle I was observing it at but I assume it would
have been.
Hopefully one might creep down into western Sydney a bit later on.
Cheers
David C

No way, only the Bureau has something comparable. I just estimate that the
storms are higher than normal based on their height to base ratio, their
distance and so on. The storms have nice crisp tops and are still rising in
some cases.

Hi all,
Some good congestus development in all directions. A reasonably strong
cap seems to be in evidence at around 5-6km - nevertheless one or two Cb
have pushed through.
I can see a Cb cell to the far ESE which also has a thick anvil that is
shearing off to the NE (similar to the cell observed by Jimmy and
David).
Current Canberra temp is 34.8 and DP of 8.9. A sea breeze front is again
in evidence and given today's greater instability can be expected to
prompt a bit more storm activity than yesterday when it reaches the
Canberra area this evening.
Yesterday's sea breeze was quite significant and arrived with gusts of
30 or 40km/hr and dropped the temperature from 38 to around 29 between
6pm and 7pm EDT. It was accompanied by an impressive line of Cu
congestus but the cap meant that only a few light showers resulted.

For those disciples of the lifted index will we be able to avoid the
temptation of a chase into <-6 territory on Saturday. Perhaps we can
continue the meeting under the rear flank of some monster storm (I
wish). The area seems to be centred over the Yass area (about 3 hours
SWfrom central Sydney) although I guess we will see what happens as it
nears. This area is also predicted to be under the influence of a 60 -
80 knot jetsream!

Get chasing that one near Lithgow, I think that it will be going severe
soon. There is much shear, so updraft and downdraft should not conflict.
Storm growth point on radar has not moved much.
I can now see the one west of Bowral, but will have no transport until
5.30pm at earliest, by then it may be overhead ( wishful thinking )

Hi Patrick,
How far is Canberra from the coast?
I wouldn't have thought a sea breeze would get that far inland. ??

I have to stay here, Michael. I am selling my chase hail-proof mobile. No
one has called though. The storms are interesting but very narrow. They are
explosive but then weakening. Another day or so, and the right conditions
will be in operation or totally stuffed.

By the way Michael, the storms are moving N-NE and so will be missing you.
You should have known that. However, I doubt they will reach us except the
anvil which is getting close from the S-SW.

There is a layer of Ac to the west and I am hoping for a storm to fire out
of this closer to home.Kangaroo Valley / Jamberoo area would place it nicely
for me. To get the Bowral one I always knew a chase to Picton was
necessary.
I did a radar animation and although the anvils are definitely stretching NE
the bases are rather slow moving, in fact the one near Bowral has drifted
east only a little. It may even die before getting east of the Hume Hwy
first possible chase encounter ).

I can see all the cells clearly including decaying cells to your S or SW.
It is good you are able to see the cells though.

The cells closest to you is the one to the W around Lithgow and the one

There seems to be a nicer cell developing around Goulbourn. I can see the
anvil shooting straight probably to the NE rather than like the others. It
seems to be more intense than others around especially at the moment.

Kevin, seabreezes regularly get as far inland (and uphill!) as
Blackheath at 1070m in the Blue Mountains, about 100km inland. They
vary from strong distinct seabreeze fronts arriving late afternoon,
and often followed within an hour or two by very thick fog as the
stream thickens and moistens, to weak affairs that trickle in late
evening.

Going on the radar at 4.50pm edst, both the Lithgow and Bowral storms
have died, and the one near Goulburn has lost intensity (max 2>10mm/hr
after about 20 mins at 10>20). Given the history of the others in the
line from Goulburn to Mudgee, I wouldn't hold out much hope of
anything substantial.

The relevant 3 hourly obs from Marla police stn are:
3am 90mm in past 6 hrs, 45mm in past 3 hours; present wx recent
tstorm, past wx tstorm, rain
6am 51mm in past 3 hours, present wx lightning, past wx tstorms
9am no rain in past 3 hours, 51mm in past 24 hours, pres & past wx
overcast.
Those are the decoded SYNOP reports direct from the observer via the
Bureau's CMSS data stream. It's a bit hard to work out how 251 could
be deduced from these figures, but the 51mm looks equally suspect,
and I would think is an error likely to be made by the new police
shift coming on and only looking part way back up the fieldbook to get
the 9am total. Therefore, my guess is that 90 + 51 = 141 is the most
likely outcome. Anyone want to open a book?

And gliders from the Bathurst Soaring club get some great lift from
the sea-breeze front that rises over the hills to the west of Lithgow.
Mind you, that is not quite as west as Canberra is relative to the
coast but the topography to the NE of Canberra is more undulating and
gentle than sheer like the western escarpment of the Blue Mountains
which might allow the sea-breeze to venture further inland. It's
possible that the Canberra sea breeze front is both assisted by the
sea breeze lower and closer to the coast but is mainly a basic
synoptic level lower and middle level east-nor-easter that carries
cool, moist air from the ocean.

While I think Laurier's speculation as to the likely cause of the
error is wrong - given that the 0900 weather bulletin (with the 251)
was issued prior to the daily rainfall bulletin (with 51), I think it
most likely that the amendment was made in the SA Regional Office
after the observer reported 251 - this is interesting information.
Only one 'past rainfall' report goes into the NCC database for
each synoptic observation, so for the 0300 observation the 45 in 3
is what went in, not the 90 in 6. I'd guessed that the 51 at 0600
could have been cumulative, but that seems unlikely from the
synoptic reports.
As mentioned, we probably won't know for sure until the written
report comes in in a few weeks.

Was anybody else watching the sat pics last night? I'm not sure where Marla is,
but on the 10:30 JCU sat pics there was a very strong thunderstorm in NE'ish SA
(was a large area of white) .. had a very crisp and intense look too it, and on
the hourly Navy sat pics it moved quite slowly. My guess is it was more than
capable of dumping this much rain.

Hi Kevin,
You have prompted some good discussion.
Canberra is approximately 150km from the coast and separated by ranges
that vary in height from 700 up to 1400m The sea breeze is an important
irregular feature in Canberra's climate - although it is not widely
known by lay locals.
As Laurier indicated it can arrive with gusto in late afternoon or can
trickle in as late as 10.00pm EDT.
It's strenghth varies depending on such variables as overall synoptic
situation (it is helped by synoptic easterly flows), temperature
variation between land and sea and cloudiness (over land).
A good example of the cloud that can form along the front can be seen in
last nights sat pic below at 7.25EDT. Note the line of cloud in the grid
bounded by 34 S and 36 S, and 148 E and 150 E.
http://www.marine.csiro.au/~lband/storm/199901060825.html
The earlier image at 3.50pm EDT (below) is also interesting as the
front is much closer to the sea.
http://www.marine.csiro.au/~lband/storm/199901060453.html
In this case the front has not quite got as far west as 150 E (looking
at the area of 34 S) and its boundary is clear to see. The absence of
cloud to the east signifies the cooler air behind the sea breeze front
and resulting absence of convection.
The animated images available at
http://wwwghcc.msfc.nasa.gov/GOES/gms5ir.html are very good to watch
late in the evening - you can follow the progress of the line inland. I
will post to the group on a day when this might be clearly visible.
In the right conditons, the sea breeze will trigger storms. Hopefully
that will occur this evening as an approachng and thickening layer of
cirro stratus has killed convection for the evening.
Another curious thing (as a former Victiorian resident) is that a lot of
summer cold fronts actually reach Canberra from the east. These fronts
are shallow and are retarded by passing overland and have difficulty
getting over the Dividing range to the west. The cold air therefore
surges up the NSW coast (as a southerly) and then backspills into the
ranges to the west. These fronts sometimes are enhanced (or enhance
pre-existing) sea breezes to produce a quite strong easterly surge.
I understand that in the tropics see breezes sometimes travel hundreds
of kilometres inland. An example, I think, is the "morning glory"
clound that rolls around the Gulf of Carpenaria in stable air mass
situations.
Sorry for the essay...but it is an interesting topic

Hi Blair and all
The raw observations from the Marla observer were:
3am: MARL AAXX 06164 94477 11584 81303 10253 20233 39697 40055 51039
60901 79196 889// 555 26237 40045 88925 77744 2100 LIGHTNING AND
THUNDER COMMENCED 2300 INTER. RAIN 2350 THUNDERSTORM 44777
The 60901 = 90mm in past 6 hours and the 40045 = 45mm in past 3 hours.
Note the comment that there was lightning & thunder from 9pm,
intermittent rain from 11pm and t'storm from 11.50pm. I think the 90mm
is credible. The hourly satpix (especially the water vapour ones) at
the time show an explosively developing anvil in the Marla area from
around midnight to dissipation around dawn.
6am: MARL AAXX 06194 94477 41584 73601 10253 20236 39681 40039 58016
71399 8399/ 555 29720 40051 82930 853// 44777
The 40051 = 51mm in past 3 hours. Note the "99" in 71399 indicates
continuing thunderstorms over most of the past 3 hours. Therefore, I
think the 51mm is credible.
9am: MARL AAXX 06224 94477 11683 70000 10250 20227 39709 40068 51028
62514 70522 8117/ 555 29214 54224 724// 81845 864// 44777
The 62514 = 251mm in 24 hours. My program replaces 9am 24-hour reports
received via CMSS with subsequent reports on the rainfall "tapes"
bulletins, which is why in my earlier message I incorrectly reported
the observation as 51mm. In fact the raw obs give 251, as picked up by
the SA 9am weather bulletin, but "corrected" in the later issue
rainfall bulletin.
As Blair says, we'll have to wait for the observer's fieldbooks to
know the final score, but my money is on 51mm *not* being the correct
figure.

One further point on this topic, it is not just in the tropics that sea
breezes can travel a long way inland. I remember hearing BOM staff
mention on the radio that storms have been noted at Hay, NSW in the
morning as a result of a sea-breeze from the day before which has been
able to retain enough impetus to be noted even as far inland as Hay.
The breezes that I am most familiar with tend to travel west-wards from
the east Australian coast. I am not aware of how far north Victorain
breezes get (I know in Ballarat we had some very hot days where a sea
breeze would have been welcome when Melbourne and other coastal
locations were much cooler - Blair identifed this situation two days
ago).
I presume that the shape of the coast line is of primary importance in
enabling a long-lived line to develop. Perhaps the Victorian coastline
is too irregular and therefore only generates more localised
sea-breezes.

Melbourne is quite similar to Perth in some ways - earlier this week there
were temperature differences of up to 10C withing 10km of the coastline
because of the weakness of the sea-breeze. Other days it can be strong
enough to create TCu orographically 20-30km inland up against the Yarra
Valley.
The Great Dividing Range which lies to the north of Melbourne often creates
a clear demarcation between temperatures as well as rain situations to the
north and the south. Quite often the cloud being blown up on the coast from
the SW disappears as the air is pushed up the ranges and it will be clear to
the north while low cloud and rain dominates the south.

I agree with you Ben. Such areas can receive such rain once in a while.

Hey Ben from Brisbane here
Would i be able to ask everyone to email the list with their location and state?
just to get an idea of who is where on the list, and how many in each state. Also
if there is anyone in Queensland who hasn't spoken up yet, could you do so? :)
thanks in advance
Ben

reporting weather information. Perhpas the new society could help in
this regard

Of course I find all this talk of sea breezes arriving in the late PM
foreign. Here in Mount Warrigal ( suburb of Shellharbour ) the seabreeze
gale ) starts by 10am most mornings. It really hampers convection along the
coast, but aids it along the seabreeze front. I suppose the last 3 days have
seen the advantage of a seabreeze, in Wollongong it has not cracked 30C. Yet
Jimmy and Michael Bath would be sweltering.
On weak days the seabreeze does not even make it over the escarpment, smog
then builds up in the SW corner near Albion Park and becomes extremely
thick.
On other rare occasions the seabreeze may cause fog at the top Macquarie
Pass, whilst just 15 kms west it is 30C.

In fact Ben, I am proposing that people that are new on the site introduce
themselves accordingly and we have a list on our site of people and their
locations.

Gilbert Sebenste relayed this information to me today.
The Purdue weather site is set to close and will be replaced by:
http://weather.unisys.com
The owner is interested in starting a pay storm chaser section,
where you have live satellite/radar, etc and your own custom products
that
you want to see. Let him know via email what you'd like to see on there.
Here is the official announcement from Dan Vietor.
