Hi All,
About an 80% coverage of very rippled Altostratus making it a dull but
attractive day.

Kevin,
Two options here:
1. A rainfall-only site
2. A climatological site (with max/min temps at least)
Wycheproof already has a long-standing rainfall-only site (at the Post
Office), so another one wouldn't necessarily be an attractive
proposition to the Bureau - except that they have, I believe, a long-
term plan to phase out post office observations, for synoptic data at
least (not sure about rainfall), so a replacement site might be of
interest to them if the PO site's future is in doubt. A rainfall-only
site would need to take observations at 0900 daily - preferably every
day, although there are a number of stations in the network that don't
report weekends. (The Bureau has historically been a bit wary of
school sites because of the possibility of long breaks during the
holidays). From the Bureau's point of view, a rainfall site doesn't cost
them anything other than stationery/postage and the supply of a gauge,
so it is more likely to be a proposition than a climatological site
(see below).
A climatological site would involve, at the very least, max/min
temperature observations at 0900 daily (unless a site were filling
a specific purpose in the network, it would be expected to report
7 days/week). There's also a non-trivial cost involved to the Bureau,
partly because climatological sites are being progressively supplied
with laptops (electronic field books) for the recording of observations,
partly because these observations are paid for (although not very
much). On the other hand, there's a bit of a hole in the temperature
network around Wycheproof (the nearest stations are Donald and Kerang),
so it might be a proposition - especially if there's the possibility
of some external funding. (If you wanted to go more ambitious than
a once-daily station, the sky is the limit, extending the full range
to 3-hourly observations of every variable of consequence). The
observations budget is under a fair bit of pressure, unfortunately.
I'll chase up who the most appropriate contact is at the Victorian
Regional Office.

early at around 10 am.

You don't often see 'rain periods' in a Perth forecast at this time

Hey All i just found this site on the Bom warnings page.. its a threat map which has both Elaine and the Developing Low off the Kimberely coast.
Id say the bom are thinking that this New low could become a VERY severe TC.
We will have to wait and see.
You Can see Karratha on this map too :)

Hi All,
Very dark Cumulonimbus building up in the Western sky. Look the most
promising I have seen it for a while. Wind has swung around to the
West/Northwest which is a good sign. Plenty of good cloud showing on the map
just West and Northwest of here so here's hoping.
At 15.00 23C, 60%, 1016, W/NW 5-10 Knots.

I recall several weeks back (Wednesday 27 January 1999 AMOS meeting) when a
similar situation occurred like today with large cumulus developing over
the mtns. They eventually produced thunderstorms during the night over the
Sydney area particularly over the northern parts. We will see what happens
as there are some serious cumulus developing on the mtns at the moment.
This is amongst or hidden by other lower level cumulus and stratocumulus.
Quite exciting. Usually, some heavy falls are probable in these situations
but only briefly. This does not mean it will happen but it might with
overnight cooling.
I was online yesterday and now am not able to receive messages but I can
send. I cannot ftp and cannot do ICQ. Why????

I hope you are right Jimmy, certainly last season and this can only be
described as rock bottom, when you get people who know nothing about weather
saying " There hasn't many good storms for a while " you know things are
crook. This weekend looks good west of the mountains, although Sunday may
see action this side too.
I have to go out Saturday night, so if chase after the AWSA I can only do so
until 4pm ( unless the chase goes south ). This I am sure will enhance storm
activity towards evening.

Mike Bailey (ABC TV NSW weather) forgot to notify of the severe storm

Hi Jane,
Doesn't look like anyone has answered your query re broard scale
patterns for this summer. OK, so I will stick my neck here and give my
perceptions of the season's broardscale patterns.
I believe that the sub-tropical ridge has generally and fairly
cosistently been situated further south than usual this summer. The high
pressure ridges have tended to be just that, long ridges of high
pressure stretched out along the width of the continent, but rather well
south, opposed to more distinct anticyclones with significant 'V'
frontal troughs between them. I haven't plotted any paths on to a map,
this is just an perception from observing daily MSL synoptic charts.
Blocking in the Tasman Sea seems to have been more prevelent this
summer also, particularly during January and early February. This tends
to consistently direct warm to hot and rather humid east to
northeasterly air flows over southeastern Australia. Strong cold fronts
have been rather elusive for the above mentioned reasons.
This explanation may be somewhat amateurish. Perhaps someone like
Blair could elaborate further.

Hi Paul,
Other than the storm we had here I have not heard of any reports from out
NW/W where the warnings were submitted for. There was nothing on the local
news (either TV or Radio).
Hopefully I can hear a few details tomorrow.
Terry.
