From: Harald Richter Subject: aus-wx: SYNOPSIS: FRIDAY To: aussie-weather at world.std.com (Australian Severe Weather Association) Date: Fri, 1 Dec 2000 09:44:01 -0600 (CST) X-Mailer: ELM [version 2.5 PL3] Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Good morning [in case you read this in the morning], Yesterday was a mixed-bag severe event evaluated from the limited data that I have. Rune gave the only genuine severe report with 2 cm hail in the Sydney area. A have the distinct impression (by looking at an IR loop) that the mature high mass-flux storms with long anvils streaming off to the SSE around 05:00 Z were out to sea. When writing the forecast I had some concern that the shortwave disturbance would be a bit too progressive and race through the area before the diurnal heating reaches its maximum. The 06Z AVN analysis (does anyone have a URL for upper-air charts from the ECMWF?) and WV show the mid-level trough axis moving out to sea around 06Z. This still leaves an upper-level cold pool in the area, but the main region of pre-trough lift favoured those big cells over the Tasman Sea. I would have liked to see the trough to be ~6 hours slower. The Sydney 03Z (2pm EDT) sounding shows a nice veering wind profile with 20 knots from 170 at the surface veering to 50 knots from 300 at 500 hPa. The shear, as progged, is sufficient for supercells. Compared to the preceding 19Z sounding the mid-levels had cooled significantly (up to 7 C between 500 and 400 hPa in only 8 hours) leading to moderate lapse rates. The problems with the Sydney sounding were (i) surface too cool (<= 20 C) and (ii) insufficient moisture (Td <= 11 C just above the ground). These problems kept CAPE values in the low ballpark (which was still sufficient for severe weather). The 05Z surface obs show a rapid increase of the surface dewpoints N of Sydney, with values approaching 17 C in the Gold Coast area. However, up there folks had to wait a little longer for the upper-level moisture to clear out delaying the onset of better insolation. That sort of thing hurts in the case of a shortwave that is in a hurry to get to NZ. Further N the lapse rates and the flow decreased as well, as is obvious in the 11Z Brisbane sounding. Does the Sydney office put collected severe reports onto a public website?

At Kent Town no rain above a Tce on one day has been recorded for abuot 23 days now. This is quite a turn around from all of the rain we had in winter and September and October. I really expected spring to bring some good storm activity to Adelaide but we've only had one in early November which wasn't all that great. I am interested in the cold front currently approaching Adelaide, although it is weakening slightly it still has some thunderstorm activity associated with it currently in the Bight region. The cloud band isn't crash hot and looks rather similar to the cool change we had on Tuesday which produced absolutely nothing here in Adelaide. I am surprised BOM hasn't forecast any storms for anywhere in SA I thought they would at least say there is a possibility. Obviously there is not much moisture around. The change is meant to reach Adelaide around midnight it would be great if even the smallest display of lightning could develop with it to produce an interesting night, this is me getting really desperate for some action. Anyway the monsoon development and the possibility of a tropical cyclone developing over the weekend is still pretty interesting if nothing happens here in little old Adelaide. _____________________________________________________________________________________ Get more from the Web.

Go N. Courtesy of yesterday's vigorous change all the low-level moisture has been driven out with only extreme NE NSW seeing some moisture return through a (shallow?) sea breeze. A solid surface H is dominating SE AUS steering some moisture inland on its N periphery. It looks like the pattern remains progressive (haven't looked at the models) so the H should not stay there forever. A new shortwave has moved into W AUS where it might couple with some better PBL moisture NE of Kalgoorlie (or it mightn't). Maybe we'll see some general thunder ahead of the trough in SA. I expect no severe convection today. Two areas are being eyeballed for general deep convection: (1) Extreme N WA/NT, especially the Gulf Country. (2) QLD, with possible remnants of flow on the back side of the exiting trough most likely to be found over SE QLD. I see the danger that subsidence near the H to the S could suppress convection. Maybe orographic lifting is needed for initiation.

Heyas
 
I have surfaced again from the frenzied end of semester that i have had. What an amazing few days storm wise for Sydney area  the last couple of days.
 
On Thursday i was stuck at uni finishing up some work. However my uni building has great fire escape platforms that have good views on north on one side and south on the other. There were cb's from early on and IMO it felt like a 'typical' Sydney storm day, with temps around the 30 degree mark, very humid (DP's of 24-25 at 1pm at UWS uni Penrith). There was a prolific moisture haze on all horizons and there  was a beautiful NE most of the day.
 
Storms popped up near Richmond and down south near Camden at around 3pm. The development over the mountains had been nice but it wasn't 'boiling' development,  just typical summer time CJs. Then some very dark bases developed basically right about Penrith. These were massive RFB with CG's popping out of them.The bases drifted over and seemed to head towards St Marys.
 
This is where the day changed.
 
These bases then dramatically changed. The whole base just expanded by about 4 of five times. The storm began precipitating over St Marys. At this stage all hell broke loose and the whole sky became this base. The rain was only a km away or so. I witnessed a massive microburst. I could see the leading edge of the burst smack thru the suburb of Claremont meadows, west of St Marys. The had moved from the SW to the NE but began to move back on me again. CG's were almost every second.
I could see the powerlines that link a big substation at St Marys, and saw a CG plummet straight into it and watched surrounding powerlines from this station all the way to my uni explode with a shower of sparks (that looked really cool by the way). The rain was holding off and stayed at Claremonts Meadows which only was about 500m away. It was amazing seeing numerous hail shafts in the burst hit small areas, and feeling that changed in temperature of the winds. Sometimes i would have really humid, hot inflow, and freezing cold outflow.
 
The hail hit us to begin with. It was big, heavy and dense. I didn't get to measure one, but conservatively they would have been at least 20c size. One of my friends in St Marys reported 6cm hail. There was heaps of damage on Mamre road there. This downpour occurred for a good 35 minutes, with the storm appearing to move on and then redevelop and close in again. Flooding was prevalent all around the uni with water seeping in under doors and thru closed windows. Because of the power-outages, free chocolate milk was given out to keep it going off. :))
 
More storms developed later at about 8pm. I received calls from Anthony Cornelius who was in Fairfield (asking if it was a 'safe' place to be). There were seeing a great lightshow from this storm which dumped flooding rains again around Emu Plains and Kingswood Park, and took out the power from Penrith thru to St Marys.
 
 
Onto friday, a different day, but a another great day. It wasn't so apparent that storms would be here. Development didn't occur until mid afternoon, and it was a different looking development, much like the day there was a severe hailstorm in Richmond last year that dumped 6cm hail around this region. A storm formed again in Camden, but later on the sky darkened up over Penrith again. Anything that was developing was basically turning into a very intense storm. At about 5:45 some dark skies in Blaxland (lower blue mountains) produced and few rumbles.Once again the stormed kept developing over me too the point where there were big gusters forming and the scud in flow was quite strong. The thunder was again constant, and the rain then came down with force. For the next hour storms formed, dumped and went over. A storm at about 7:30 dropped 2cm hail  for about a minute. This was accompanied with an extremely close strike that had my poor modem shitting itself. The storms cleared from here around 8pm'ish.
 
 
 
Well that long account was from the last two days. Severe storms, hail, explosions and an ice cold chocolate milk. What more could a person want.
