I would suggest you ask him to pass this on to you as it has the radar going red before it. Did you notice any rotation with the lowering say 5:30pm onwards. The lowering looked from here very suspicious. I have the outside view of the storm and it looks very interesting. At 6pm the storm was in collapse mode.

Fortunately, the cloud is in patches with breaks in between. In combination with the cloud from Steve, high levels of moisture from the NE, the Canberra and SE NSW seems to have a very unstable atmosphere. I am happy to report that towers are going up all over. Unlike the other day when there was potential which was killed off by thickening high and middle level cloud, today we have had strong heating for the last couple of hours. In fact the sky looks the best that I have seen all summer here (not that the benchmark is all that high...). I think there will soon be a few good red blobs to see on the radar.

Date: Sun, 12 Mar 2000 12:57:47 +1100 X-Mailer: Microsoft Outlook Express 4.72.3110.5 Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Les, Thanks for your response to this. Others may correct me but I do not believe that the processes at work in the inland summer troughs of Australia have been the subject of too much detailed work. This is no doubt due to the low population densities in the areas where these troughs play a major role. This means that - especially compared to the US - surface observations are geographically sparse and detailed upper soundings are even more sparse. It also means that the impact of severe weather in these areas is also less likely to impact on many people (again unlike the US) thus reducing the imperative for sparse research funding to be spent on studying these troughs. By contrast, I understand that there has been a lot more work done on southern cold fronts and their intereaction with the Australian landmass particularly near the coast-line. Cold fronts have a much greater impact on probably 80% of the Australian population - with their impacts ranging from the benign end to a spell of extreme heat, through to the severe storms (wind, hail, tornadoes etc) as well as impacts on bushfires (varied and complex depending on the part of the country and local topography). My personal impression is that the BOM is not consistent in placing the locations of trough lines (and dry lines - if indeed Australia does have anything like a similar phenomenon to that which occurs on the US plains) on MSL analyses that are made available to the public. This may be because the line is less well defined and harder to place than a temperature discontinuity or it may be that other types of discontinuities have not been regarded to be sufficiently significant to include on a MSL analysis. I think it would be quite interesting to see some Skew T's from either side of an active Australian inland summer trough.

Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Susan from Balmain Had to laugh when my daughter in all seriousness on Friday night told me that the reason for all the rain was TC Steve which was now in Sydney and dumping all this rain we'd been having - asked her where she heard that and she told me it was the TV station presenter called Monty or something - she claims he is very good. She told me he had a weather chart showing Steve centred over Sydney. I immediately showed her TC Steve's position near Monkey Mia. She was very unimpressed with Monty and wanted to know how they (the presenters) could do that. Lets hear it for TV weather presenters (not!)

Date: Sun, 12 Mar 2000 13:59:04 +1100 X-Mailer: Microsoft Outlook Express 4.72.3110.5 Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Susan, If you follow one of the satellite animations, you can get a good idea of where the moisture has come from. For Sydney last Friday try either http://cimss.ssec.wisc.edu/tropic/real-time/shemi/images/images.html (probably getting a bit late for Friday but shows the origins of the current cloud over SE Aust quite well or http://www.ssec.wisc.edu/data/comp/ and select cmoll.mpg (you get a week's global animation) >From memory the cloud band over Sydney on Friday at one stage a couple of days earlier interacted with cloud emanating from TC Steve. So it is probably technically true to say that some moisture that was included in Sydney's rain came from Steve; a lot more came from the Coral Sea however. As with all rain events, however, moisture is only part of the story. There has to some trigger to get the moisture to lift and produce rain - in this case there was an upper level disturbance over NSW. Very local to Eastern Australia and not associated with Steve. Weather is certainly very complex - this often doesn't make for good 2 minute grabs which the Montys of the world have to make do with. This doesn't absolve them of the requirement to be more careful with the truth!! I have also noticed over recent months that the ABC has been guilty of repeating the day before's synoptic chart or satellite images. This has happened on a number of occasions. In some cases Mike Bailey (the presenter) has obviously noticed this and rapidly moved on. Or if it happens on a weekend the news presenter has no idea at all. Either way there is no owning up to the error which I think is very unprofessional. Little wonder that the general public in Australia has a fairly poor understanding of the weather.

I would tend to agree with you, it looked very promising for a little while. It was also rather wide spread, reaching a long way out past the coast but we could see that, that part of the storm wasn't going to do anything. It was also hardly moving at all and stayed practically in the same position the whole time that we were there.

Just wanted to point out that the AVN and MRF models will basically be exactly the same under 72 hours.. from what i've been told, they are basically the same models, but the MRF forecast go out to 144 hours and the AVN forecasts out to 72 hours.. if you compare the forecasts side to side you will be able to pick this up.. The WAFS model is also basically exactly the same as the AVN model.. once again if you compare the two model forecasts you will pick this up instantly.. Another eventless weekend in SE QLD weather wise - but i'm hoping a trough forecast for SE Australia over the next few days will do something for us later in the week.. paulmoss at tpgi.com.au wrote: > > In addition to that COLA & Tim Humes WAFS shows the same > Low central presuure of about 999 or so. > > Help.............. > > On 11 Mar 00, at 22:54, paulmoss at tpgi.com.au wrote: > > > Hi Laurier, Blair or anyone who calls themselves a models expert. > > > > Please put me out of my misery. 72hr AVN MRF shows a possible > > Tropical Low / Possible TC right near us.

The view I got was from the rear. If you saw it from the side you are in a better situation to see it. It will be good to compare the video footage and photos and make a decision from that as to what it really was. I only really began to take notice say from just before 5pm and then went across the road after 5pm when I saw the red on radar and the other cell had collapsed. We will see the footage on Saturday. As Dann Weatherhead noticed and I noticed, the rising updraught of the last major cell lasted quite a while and also had a leaning tower to it straight up from the lowerings.

What struck me was that both of these storms from what i could see were very similar in structure. They formed quickly, had successive updrafts which were stronger each time and seemed to organise themselves very quickly from initial CJ--congestus (..still sounds weird Anthony =/... ), to Cb stage. However, the more northern storm seemed to die, when the other southern storm really built up more. From my position, the rear end of the storm had a great flanking line, there was even another CB further north-west of the storm, however i believe this ended up feeding into the main updraft. I have photos that should be up tommorrow evening or tuesday sometime.
