Hey all

I have just finished the first part of a major overhaul of my satellite
picture. i have added a new front page which has links to sat pics, a notes
on the sat pic section detailing the main features on the current sat pic,
any events that are happening (TC formation).

I will be including a sat pic education section in the not to distance
future to give tips on how to identify features on sat pics and use them for
forecasting.

The SE sat pic animation is linked from the new main page and is still
updates hourly with a new gmsd image.

All can be seen at http://seaustraliasatpics.virtualave.net

(note new URL!!!!)

April rainfall at my place in Blackheath = 65mm

We had our first "Roof Frosts" from 19/4 through to 22/4 with our first
ground frost for the year on the 23/4 and 24/4.

Coldest morning I recorded was 1.5 on the 23/4.

Warmest Maximum was 21.5 on the 3/4

Lowest Maximum was 9.8 on 22/4


Here's hoping we get a bit more rain this May than May '99 where we only
got 13mm.

Blair,

Did you ever find that piece of paper for Oberon and Katoomba snow days?
Also, has snow ever been recorded settling on the ground in the Katoomba
area in May? 

A guy at tennis was convinced there was snow on the ground here in March
in the late eighties, he's a pretty reliable source for a casual
observer of weather.

Out of interest, last year I observed 8 snow/sleet days here in
Blackeath, all of those were light with the exception of 14/8 that saw
snow fall for a couple of hours and settling before rain melted it at
around 9pm.

I have a question mark over the 10/11/99 where we had a few mm the
preceding night and the minimum recorded overnight was 1.5, however, no
snow was observed when I walked outside at 7am.


Thanks,

Lindsay Pearce

   It is now mid afternoon Monday and it is interesting to see that the low
did track w/sw towards SE QLD with a gale warning now for coastal waters off
Brisbane. The summery upper atmosphere continues NE of the jet that runs
from Alice Springs through eastern Victoria thence to NZ. The tropopause is
around FL450 near Brisbane, FL410 near Sydney and FL360 near Melbourne on
the other side of the jet. This jet reaches 150KTS at FL360 near NZ where
there is an approximate 10000' split in the tropopause. Anyhow hopefully
Brisbane may get an inch or two from this low.

Dear all,

Nice trough passing through Victoria on Saturday night.   Pressure jump
following the passage of this trough over Central Victoria was quite strong.
My barograph trace showed a steep enough rise to attract a mountain
climber!! and it also showed that as expected the pressure was building
rapidly to the northwest & west of Victoria.  Interestingly, the cloudband
associated with this trough was distinctly lacking in high cloud above
25,000', and a check of the 300hPa sounding showing -32C may account for
this.
Meanwhile in the weird and wonderful weather section, a rather unusual low
pressure system near New Caledonia has been wallowing about.  To me it has
the signature of a mid-latitude cut-off low pressure system, and will
probably remain that way moving slowly southwest.  If you think you can
generate decent bath waves by moving backwards and forwards in your bath
(I'm sure all of you have done that!), the pressure gradient between this
low and the high near New Zealand should generate some respectable wave
heights over south east Queensland and northeastern NSW.  Another oddity is
a disturbance over NE South Australia.   This system is moving NE, while the
Coral Sea system is moving SW.  The air over NE SA is somewhat colder (-36C)
while the soundings over Brisbane are -28C.  It certainly would be
interesting if some of the colder air over SA drifted NE over Queensland.
I'm sure the Queensland weather enthusiasts will be keeping an eye on it.

A wish list forecast we'd all like to see - a super east coast low develop,
move southwards along the coast and then moor itself in Port Phillip Bay.
Unfortunately though for Victoria, pressure remains rather high with cold
nights and very pleasant days until the arrival of what appears to be a
rather feeble frontal system Wednesday night through Thursday night, and
then yet another high pushing into the western Bight region for the weekend.

Wildcard: the low pressure system NE of Brisbane moving SW to the interior
of Queensland and then shifting S towards Victoria, although steering flows
appear to favour a shift towards the SE as it approaches the Qld coast.

Regards,

Clyve

We already have a nice NE swell here in the Illawarra, it was 4ft yesterday,
but up to 6ft today. This is a powerful ground swell, not a choppy lumpy
6ft.

Hi all,

Well - if you wanted some interesting weather in SE QLD, you had to go
searching for it (unless you lived right on the coast).  So after 2 days
of cleaning the house, I left to meander up north along the coast just
after midday.  (A reminder to SE QLD'ers that I have overseas rellies
staying with me for a week starting this Friday, so make sure you have
plenty of film for the weather! <g>)  I drove up to Redcliffe, and sat
at Woody Point for a while and ate a sausage roll while being amused by
watching seagulls fly backwards in the wind.  I had remembered reading
this on a MSC report, and had always wanted to see it and video tape
it.  However the seagulls had different ideas, and I swear that as soon
as I took the video camera out...they all went back down to the ground. 
This happened twice!  Winds were quite strong, 15-20kn sustained...gusts
to 30kn.  Similar conditions at Margate Beach, and it seemed quite rough
for a bay!

I then headed up to the Sunshine Coast - first near Caloundra at the
lower end of the Coast.  The oceans were very rough - waves were around
2-3m (no 6.5m waves on the Sunshine Coast that I saw :< ) no doubt they
were further north though.  Still, very large swells and the ocean was
whipped into white foam.  Winds were averaging around 30-33kn in the
exposed reaches.  I got to one interesting little spot on a small cliff,
that acted as a 'funnel' for the wind to travel through.  The wind here
was particularly strong, averaging 40kn, with estimated gusts to around
50kn!  It was an effort to stand against the wind, and videoing was even
more fun with it being impossible to hold the camera still (and the
camera strap whacking my face).  None the less, I loved the wind!  I was
about 10m above the beach, but I was still getting sprayed from the
winds carrying the waves spray onto me.  Actually, much of the Sunshine
Coast was like that - particularly near the coast, very misty.

Maroochydore was equally as interesting, with very strong winds.  Cotton
Tree Beach has very severe beach erosion, with the waves undercutting
the enbankment to the trees.  I had never seen so much foam in my life
though!  It was incredible, just this white froth everywhere!

As Clyve mentioned, this low does appear to look somewhat
extra-tropical.  However during today I concluded to myself that this
was a tropical low due to the following reasons:

- Standing in the wind was rather warm, it was not cool/cold at all,  
just warm.  Normally SE'ers are cool/cold - and while this will sound  
funny to some, you can feel the difference between a TC SE'er, and a  
ridge SE'er.  And standing out on the beach, I thought it felt like a  
TC SE'er.
- Warm rain about, I was amazed to see the thermometer *climb* to
24.3C   during a shower here this morning.
- The low formed and remained north of the 300mb ridge (although the  
'wildcard' in this is, was it originally caused from a 500mb upper  
level trough that moved through about 5 days ago???)
- The upper levels warmed considerably on the approaching of the
low.     With our 500mb temp going to 0C at one stage!!!  Certainly a
sign of   tropical air.  The 300mb temperature has been sitting between
-27C and   -30C for the past few days.

I think that perhaps the low exhibits the characeristics of a Hybrid
TC.  A Hybrid TC has its maximum winds well away from the centre, and
generally an extended area of gales on one side.  Gales extended out to
740km from the low yesterday, but this was generally only on the
southern half.  Gales would barely exist to 100km from the centre on the
northern side.  However, the circulation is still completely present,
you can see the LLCC quite nicely on GMSD.

I'm open and welcome to anyone else's comments/suggestions though.

We've mainly had mizzle here this evening, but every so often we get a
very heavy shower with squally winds.
