Cold front just moved through the city causing strong winds and heavy rain
just as I was driving home from work, I couldnt even see the city
skyscrapper lights from a few km's away on the freeway as the heavy rain
was coming down.

93km/h has already been reported on Rottnest Island, and theres a nice pool
of cold air behind the front that could cause thunderstorms and further
strong winds. A severe thunderstorm advice is current.

PRIORITY
FOR IMMEDIATE BROADCAST

SEVERE THUNDERSTORM ADVICE
Issued at 12:55 am WST on Friday, 16 July 1999

People in the Southwest District, including the city of Bunbury, and the
town of
Busselton, and in the Lower West District, including the Perth Metropolitan
area, and the city of Mandurah, are advised that there is a risk of severe
wind
squalls associated with showers and thunderstorms overnight.

The strong squally winds gusting to 100 kilometres per hour may result in
damage
to property.

At 12.30am, Cape Leeuwin was reporting squalls to 93 kilometres per hour, and
Rottnest Island was also reporting squalls to 93 kilometres per hour.

People are advised to secure loose items and move vehicles under cover.
Driving
conditions in squally winds and heavy rain will be hazardous.

The next advice will be issued at 4.00am.

Jacob

Hi everyone,

Good to see others from the list asking products to be for Australia as 
well. Well this following has been improved and seems to be working again.

http://wwwghcc.msfc.nasa.gov/GOES/gms5ir.html

I would take a look at the past 6 animations and you will see an area of 
cloud heading for Sydney and increasing in intensity with colder cloud 
tops. Even though the low has progressed away from the coast, it is has not 
properly cleared and it looks as though some more activity is on its way. 
The low near South Australia has again "weakened" with the cold front 
associated with the cold air moving SE. This has been the pattern for the 
last few weeks although this one started a little more back... The wind 
direction in the upper levels seem to be from the NW which over ENSW are 
always a good sign with NW cloud bands for the development of lows over or 
off ENSW. The air aloft within the cloud band indicates the air is still cold.

During the night, we didn't only have showers but some very heavy showers 
at times. 7mm fell in reasonably quick time compared to the falls during 
the day <1mm of this total. See what happens.

Hi everyone,

Jimmy here. We have had some interesting weather lately. So why not go and 
talk about it. I am planning to go out to the Mean Fiddler tonight around 
7:30pm (I also went last night) and anyone is invited to join in. It is a 
nice atmosphere and it is quite popular. The Mean Fiddler is located on the 
Windsor Road Rouse Hill on the same side of Windsor Road as the Rouse Hill 
Golf Course but just across the side road near the Golf Course on the right 
hand side coming from Parramatta. Come and enjoy. It is a great place to 
visit. There are dress regulations so you need to wear shoes and collard 
shirts.

See you there.

Whilst Australia's snow-lovers are starved of the white stuff, there
has been snow during the day in Calgary, Canada, with the temperature
hovering all day around 4-5 degrees.

I've heard of snow in Alberta in early and late summer, but never in
mid-summer. (Calgary's average maximum for July is 23). There was a
significant fall during the last week of August in 1992.

Hi Everyone

What a wild night it was here in WA last night. Several places around
the south west corner of the state reported wind gusts close to and
greater than 100km per hour.

Cape Naturaliste reported the strongest gust at 117 km/h, Cape Leewin
recorded 111 km/p, Rottnest Island recorded 94km/h, Swanbourne recorded
91 km/h and Ocean Reef near where I live recorded 94 km/h.

I've been out for a short drive already this morning and as I was
driving past the local park, there was many branches down from trees,
nothing huge but alot of smaller ones. There has been a report of
powerpoles down in Doubleview. I'll be going down there to have a look
at the damage sometime later today.

Regards

Greg

Hello Everyone

The barometer is showing pressures are dropping so our run of fine but
frosty weather, which has been very pleasant, must come to a end.
We can look forward to drizzle and showers tomorrow  with the wind
picking up on Sunday as the first of the cold fronts heads our way.
Strong winds Monday with the passage of the next front and a cold
Southerly change bringing snow.
We had wet warm May, a mixed bag for June and early July with strong
high pressure systems stalled over us producing easterly winds!!! Will
mid July
be the start of Winter?

Hi all,

I went to the BoM today to talk with Jeff with a few things, and also
share some information with him that I found by going through old
newspapers on microfilm last week.

Anyway - Jeff gave me a job to do, and that was to type up the list of
severe t'storms (in particular hailstorms) in QLD between 1935 and
1953.  It also contains othern information on other significant
thunderstorms in Australia.

One that caught my eye, was a Sydney thunderstorm, of which I've typed
out below:

1.1.47 SYDNEY.  Roofs damaged in hailstorms.  Also furniture, etc.

And then below this it says:

1.1.47 SYDNEY (additional to above).  Record hailstorm, over a million
pounds damage, neon signs, aircraft, cars, gardens, electric wires,
damaged.  Trees stripped.  Roofs caved in, tiles, windows panes, roofs
smashed.  Over 300 people injured by hail, glass and tiles and Randwick
race course and Bondi and Sports ground.  Hail stones up to 8 inches
across, bigger than cricket balls, worst area Hurstville and Bankstown
northeast to the Harbour.  Greatest damage east of City and eastern
suburbs, area 15 X 12 miles affected, lasted 10 minutes, about 2.30pm.

For those who are wondering, 8 inches = 20cm across.  And one million
pounds in 1947 would be a phenomenal amount of money if they were
inflated - my guess is if it were inflated, then this figure would be
around the figure of the April 14 t'storm.

Certainly, a very interesting event - does anyone else have more
information on this???  If anyone is interested in researching this
event (going through newspapers for articles and clippings) I will
gladly go halves with the cost.  Please email me personally.

Anthony from Brisbane

Hmm, not quite the same Anthony, but close.  This thing had a very smooth
inverted cone shape, and a pointy tip that was swinging around it.  I'm
getting the prints developed in the next few days, so we'll know then....

Anthony...
The New Years' Day ice storm in Sydney was - probably until recently -
the worst hailstorm in the city's history. It moved from from the WSW
early afternoon, effecting mainly suburns just south and east of the
city. A remarkable feature of the storm was the lack of rain  - all
reports of the time mentions just lumps of ice. The maximum suburban
rainfall was 3.8 mm (15 pts as it was then.)
roofs and cars were the greatest damage. It moved from Earlwood and
Mascot towards the city and Bondi - most of the injusries occurred near
the beaches because it was a hot day and thousands were at the beaches
of Bondi and clovelly where the hail was heaviest. By mid afternoon, the
winds swung WNw and skies cleared.  another interesting feature of this
storm was that no other storm was reported anywhere in NSw that day - or
least anything of note. The sky lights at Central Railway station which
had lasted for 80 years were all smashed and further injuries occurred
there from the broken glass.
My parents - who were not at all interested in the weather - remember
this event with clarity - they describe the roaring noise approaching
and the absence of lightning or thunder (or at least hearing thunder)...
they also remember the smashed hail and the dog battered to death in
their street but hail stones. they also remember the unusual shape of
the lumps of ice.

 When did they occur?. I'm not talking about the heaviest snowfall events
or very intense frost inducing anticyclones. The sort of event I'm
referring to would be something like the cold outbreak of early July 1984,
with snow and ice right up to southern Queensland.

 BTW the intense low that flooding Sydney over recent days has now crossed
the Tasman and delivered heavy rain to the northern North Island.
Canterbury is expected to get good easterly rain tomorrow - already raining
now in Christchurch, but not heavily.

Hi Ben,

I have here a small exert of a report from the BoM of a cold outbreak on
the 19th of July, 1965:

During the daylight hours of the 19th of July 1965, falls of snow
occurred over a 90,000 km squared area of QLD, extending from the NSW
border near Boomi over the highland country bordered on the east by the
Auburn Range and the Bunya Mountains, extending westwards beyond the
Maranoa River,  northwards over the geadwaters of the Warrego and Upper
Belyando to the Drummon Range, and then beyond the Tropic of Capricorn
to the Clarke Range and Eungella  National Park NW of Mackay.  Falls
were widespread in many areas where snow had never previously been known
to occur, it is believed that the light snow which fell just on dusk in
the Dalrymple Heights area NW of Mackay is the northernmost occurrence
of nosw in Australia recent times.

Records exist of snow's having fallen in parts of the QLD Central west
early this century, and snow was once reported in the Cloncurry area,
but melting before reaching the ground.

An intense high pressure system in the Great Australian ight was 
directing a strong inflow of very cold, dry air into QLD.  This inflow
was enhanced by the developmet  of a small, but intense low pressure
system off the coast near Brisbane.

I have no other info though...but hope this helps you or jogs other
peoples memories.

Interesting, perhaps it was an LP supercell. There is a short summary
of this event in Storm News (Issue 7, page 4) although it doesn't
contain any more info other than what you provided Anthony (perhaps the
author of it might be a good contact) - cricket ball sized hail and
eyewitness reports of hail the size of two clenched fists. 8 inch
diameter hail sounds a little too scary so maybe someone converted the
measurement but forgot the unit - then again with the damage reported
who knows how big the largest stones were.

Hi Everyone

Today i witnessed a very interesting cloud formation. I was driving along 
the Windsor Rd at about 1:30 shopping for Australian Native Plants. To the 
South of me a very dark cloud base was quickly passing by me. Attached to 
this base was a dynamic scud formation. I watched it with no other 
fascination other than a interesting cloud. But as the cloub base got 
nearer, the scud grew longer and strangely twisted becoming more smooth.
This took my attention.
Then I noticed around where the scud was attatched to the cloud base was 
small, individual vorticies. I counted five. They kept spinniing themselves 
out then reappearing. Then within a minute the whole this just twisted into 
nothing.
