The rain has eased a bit but there is still pockets of moisture around. ALL rivers are awash as record rainfalls hit inland areas of the Canterbury in the South Island of New Zealand. 24 rainfall totals of up to 240mm reported in inland areas.( I omly got a beastly 46mm and Bob Crowder down the road got 49.3mm here in ChCh) Road and rail links cut. Farms awash and people forced from homes due to rivers bursting their banks. Civil defence called out. No lives lost yet, well I hope not, human and animal. Record snowfalls in the eastern Southern Alps. Winters worth in a 36 hour period. Mt. Olympus get it biggest snowfall ever in a 24 hour period, 120cm A good well developing low pressure system is to blame with a moist SE airstream feeding into the the South Island from deformation cloud around the NE part of the low. More reports later as they come to hand. I think you Australians will cop a similar system over the SE of your country in the next couple of days, a well developing depression, cradled by a bubble of high presuure that seems to be lost in the higher latitudes below Tasmania. According to EC that high should move towards and NZ and cradle that low pressure system over SE Austrlia.

I guess in the most simple terms, the answer must be no. No you can't without a great deal of ambiguity and a high failure rate and low probability of detection.

This "cold outbreak" is looking curiouser and curiouser. As at the morning runs today, the overseas models are starting to come into line up to midweek. Unfortunately, the local product seems to have gone AWOL, with no LAPS or GASP based on 00 UTC this morning as of 7pm EST. So the following musing is based entirely on the latest EC, AVN, NOGAPS and JCU output. They all agree that by Wednesday a monumental block will have developed with a high 600 to 800km S of Tasmania (EC has central pressure 1035!!, AVN 1030, NOGAPS 1026 and JCU 1027) and a fascinatingly broad area of low pressure over the entire SE mainland. The EC has a 1003 low off Gabo, but the 1008 isobar encompasses all NSW, Vic and much of the western Tasman. AVN and JCU are broadly similar, while NOGAPS holds the low back with a more pronounced centre near Mt Gambier. The low is evident and substantial at all levels, and is vertically stacked. The jet at 200hPa splits around the block, with the northern limb over southern Qld and a substantial southern limb dipping down to 70S. There is no strong southerly jet -- as there was in the late May outbreak, and which is characteristic of true polar outbreaks -- but only a vast area of stagnant cold air over NSW and Victoria, with 500hPa temps of -30 to -33 over most of NSW, Vic and Tas. The overseas models have been warming the lower levels on successive runs -- AVN and NOGAPS both have 850 temps on Wednesday between -1 and +3 over SE Australia, while JCU is between +1 and +3. Consequently, thickness estimates have risen a bit on earlier ones -- EC and AVN have all NSW/Vic/Tas/SE SA sub 540 but nowhere is sub 536; NOGAPS, for once, is bolder, with the same area sub-540, but most of eastern NSW sub-534, as less warm air is entrained into the held-back low. Unusual weather breeds in unusual situations, and this is shaping up to be one. The upper temps are certainly cold enough for low level snow, but the more recent 850 temp estimates are making it less likely below, say, 1000m. On the other hand, with the models maintaining 500hPa temps at <-30, iincreased storm activity seems likely, possibly over an enormous area. I'm keenly awaiting the GASP, to see which way it has headed. Laurier On Sun, 20 Aug 2000 12:34:39 -0700, Lindsay Pearce wrote: >Yes, I'm interested in Laurier's reflections too.

Unfortunately, I was on the trailing edge of the activity and I thought that I had missed my chance of seeing anything exciting - although some of the clouds were very spectacular. Upon reaching Cessnock, I encountered a large Cu followed by an awsome CG directly ahead of me!! Unfortunately it was the only one I saw. I was at what was more or less the clearing edge of the trough and witnessed a spectacular shower cascading from the base along with an almost complete rainbow as it was illuminated by the afternoon sun with clear skies to the west. All in all, worth it despite not seeing anything extraordinary. Better than some previous "bust chases" anyway. - Paul G. ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from aussie-weather send e-mail to:majordomo at world.std.com with "unsubscribe aussie-weather your_email_address" in the body of your message. -----------------------jacob at iinet.net.au------------------------------ Date: Sun, 20 Aug 2000 20:06:59 +1000 From: MSC - Jane ONeill X-Mailer: Mozilla 4.5 [en] (Win95; I) X-Accept-Language: en To: Aussie-wx Subject: aus-wx: WEATHER: Temperature increase Sender: aussie-weather-approval at world.std.com Reply-To: aussie-weather at world.std.com Evening all, Temperature dropped from 8.6C at 6pm to 8.3C just after 7pm with a SSW air of 1-2 kph - it's now (an hour later) gone up to 9.1C - wind is same direction, same speed.

The chase was with Mario and Alex (his maiden chase). Left home 9:30am and we were heading into the Hunter by 11:30am. At the end of the Putty Road, there was a glaciating large cumulus or minor cumulonimbus. This produced a shower of rain as we passed through. Cumulus congestus developed during the early afternoon but it wasn't until around 1pm when the first main cells were passing through. Most of the cumulonimbus were very shallow - looked like Victoria:) But seriously, I made the mistake of going towards Muswellbrook as I thought the largish cumulus line E and S of Singelton would not do anything. But by the time we go to the Muswellbrook bypass, we decided it was a good idea to stop. Wow. There were towers shooting up along that line and another was also going up to its SW. So we headed back to Singelton. As we approached, we observed a hail shaft and then an impressive lightning bolt out of the side base of the main developing cumulonimbius. This cumulonimbus had reasonable structure with the top half billowing backwards. Quite impressive. We could see that the storms to the S had also been following along the same line and the region in between was going up as well. As we neared the Singelton Heights area, there was a nice dark flat base. The lightning detector was very sharp and the activity to the SW and also the main cell had lightning activity every 5 seconds or so. After I made mistake two, we decided to head back and head towards Dungog. We were attempting to get close if not into the region of light green tinge and most probable hail. We ended up catching up but slightly passing to the left of the main storm region and therefore missed the region of hail. I was surprised at how active this storm remained. By the time we got a road to go through it, it had weakened significantly - damn. However, as was the case with this cell, the region to the east had intensified and showed some impressive updraughts lit up by the sun. During the evening, we got a message from James Harris asking us had we observed the large storm off the coast. It was hidden but very impressive. Hopefully, James got onto that one. We had to head home as Mario and Alex had another hour to go after arriving at my place. I was impressed by this chase but learned that chasing shallow cumulonimbus has it advantages and disadvantages... If you go too far you can get out of their path quickly but you can also get back in very quickly even though they looked distant. I must admit, driving meant I had misjudged some of these cells. I also have to take driving lessons. Alex, in the back seat, suggested as we left the Pretol Station lookout near Singleton: "Umm, Jimmy you are on the wrong side of the road". I think he almost left scud marks in his undies. Anyway, an enjoyable Sunday drive.

I just wish that some of that cold air in the south Tasman between Tasmania and NZ South Island would move just a bit further north than progged. It just clipped Hobart today (max of 8C) and looks like a great featureless blob on the sat pics. With the models showing this cold air field having some of the lowest thicknesses (below 500dm) and 850 temps (<-28C) I can remember seeing in the COLA MRF Australian map in a long time (albeit at its southern extremity), the Invercargill sounding tomorrow will be an interesting sight. Some pretty low-level snow for Otago coming up?? I guess that is what happens when you get a high parking itself in at 55+ south in the Southern Ocean in August.

Basically, what I mean is that the air is coming from the NE, yet from a NW'ly wind. This can happen if we have gradient/geostrophic NE'lies over much of the area to our north, but then due to pressure changes it swings back around to the NW, and we get a NW'ly with NE'ly properties. Perhaps something similar happenered, where the upstream wind direction changed and tapped into some warmer air? Just bouncing ideas...

But at around 11:30am things stabilized somewhat, soon after though more CJ's developed to W, SW and S - I went to Boonah to see what I'd be able to find. Things kept going up and down...but I was very dismayed when I went to open the car door after being at Boonah for 40mins and got a static shock! I immediately decided to head east, as nothing was going to happen with such little moisture. Also, an interesting area of development was to the SE, and interesting CJ's to the NE. Unfortunately, it all fell apart. Back in Brisbane, I recorded a DP of 17C! But within an hour, the W'lies came through and the FP was now -4C!!! Had we had the moisture, it would have been a fantastic day - dam those W'ly winds, and winter troughs! Wednesday could run into the same problem as today, but no doubt as usual I'll be trying to shuffle my week around to get as much time free as possible on Wednesday.
