Title: NSW / QLD Severe Storms and Lightning: 2 - 8 Dec 2008
Post by: Michael Bath on 03 December 2008, 09:53:46 AM
Today and the next few days ahead look unstable in many parts. Today was lacking moisture but things are kicking off along parts of the Mid North Coast. BoM has issued a warning for damaging winds and large hailstones. Main event so far is Port Mac to Kempsey area.

Spotted a small funnel from congesting cumulus to my north a little while ago - it persisted a few mins.

This cell near Grafton was the only photogenic looking piece of cloud around here today. Everything else that tried to get going suffered badly due to the lack of moisture. Bring on the next few days!

I have a feeling I may have seen the same funnel Michael. Was a mediocre looking cu that died off fairly quickly leaving the funnel behind. Did it look a little like this?

On my way back from Lismore there was a more substantial looking Tcu over the ranges to the north. You could really see the windshear pushing it over quickly.

Today looks to be more of the same. Still not complaining, beats Sydney's storm efforts of late!

Yes - that's it James. The congesting cumulus sequence was captured on the webcam - and even the funnel - which corresponds to the higher updraft at 3.01pm. This sequence is from 2.55 to 3.07pm in 2 min intervals.

Hi guys,

That's an interesting little funnel attached to those Cu's!
 
Certainly looking forward to seeing a few storms out this way over the next few days, particularly with such high temps! We were forecast a top temp of 37ºc but it's already reached 39.2ºc! Winds are light but very dry and hot (partly helping those temps to rise).

I would expect any storms to be very lightning severe given the current heat. This should also help drive the convection nicely. The shear has been good lately, lets hope it stays that way with this system :D

Take care if chasing!

Personally I think things are looking pretty good today. Storms have already fired in NE NSW and on the ranges in Qld. Currently, further west where the storms are firing in Qld the surface winds are NW. On the eastern side of the ranges the surface winds are more N/NE. Also the moisture is much better east of the ranges, for example, Beaudesert latest obs show 31/21. Moisture depth aside, this gives some pretty extreme surface-based instabity. I also think that moisture depth is pretty good with the Brisbane sounding showing excellent moisture in the lowest 100mbar. I would consider this the minimum moisture depth for severe storms. Storms may really intensify on the eastern side of the ranges in SE Qld and NE NSW with a real chance for supercells with large hail. Further south around Port Macquarie it wiould seem moisture depth and capping are really big problems. Recent obs show 28/22 with E'ly surface winds which sounds amazing but if moisture depth is shallow and too capping is strong then nothing may happen there at all.

The second of two cells has just gone over here at Lismore, with the second having larger hail around the size of a 10 cent piece.

Jason, I also saw that the same cloud and hoped that something would evenutate from it. Oh well if only it was earlier in the day when it was warming, then something may have come from it.

Gday All,

Well after our third storm of the arvo I've finally got the chance to get some pics up.
Because I was looking after my kids today I couldn't venture very far from home, so I managed to duck out to a vantage spot a couple of kms west of my place to get some pics of the second storm that came through. The cell was fairly high based, but still quite photogenic so I snapped away. I even managed to score some handheld (no tripod) daytime CGs which I was pretty pleased about. Also there a couple of pics of the small hail that fell.

The next sequence of shots are of the third storm of the day which was highly lightning active. My back steps aren't the best vantage spot for taking pics but it had to do for today. Spewing about the CG behind the gum tree. This cell had a nice rain free base as well and the CGs were punching out ahead of it, which was pretty special to witness.

Well I thought it was all over here today but I was wrong. An hour after I posted it started up again and boy did it thump!

Everyone bundled into the car and we ended up getting some really good shots out the Lismore on Wyrallah Road.

Noticed on the radar the nasty looking cell that tracked south of Coraki. Looked intense at times.

Michael - maybe your cameras should be looking that way? From what I remember when I lived in Coraki the storms mainly tracked in from the SW or W.

Apart from getting up there for the BBQ Sat week I now have to go to Narrabri for an install on the Thursday. So Wednesday next week will be driving up and maybe camping in the Warrumbungles or nearby if the weather is OK, otherwise hit a motel somewhere. Being a work trip they would pay for it (but I would rather camp!). Thursday do the job and get to Coffs Harbour if time permits that afternoon, or stay somewhere along the way and get there Friday. Lismore and back to Coffs on Saturday, then drive back to Sydney Tuesday or Wednesday depending on what we have to finish before Christmas. So hopefully won't arrive during a dead patch and get a chance to photo a few north coast storms as nothing here has been that photogenic. Great hail, but any lightning for good shots just happened from near home (or been buried behind downpours).

Awesome set of photos Jase! That last storm of the day sure put on an insane CG show - the HD video will be amazing. Literally dozens of staccatos hit out the front of my place in and around the valley - you could see houses being hit.  Rodney was over and my two kids were taking pics too.  No hail here but some very heavy rain and some wild winds.

A couple of the photos:

Hi everyone,

Just had a cracker of a light show earlier on from an unexpected line of cells. Lots of anvil crawlers branching out and quite a few CGs punching from above. It was definitely high based judging by the echoing high up and very electrical. Sort of reminded me of the 29 November 2006 set up.

Fantastic shots MB, Jason and Rodney. Two strikes near the same area eh? What are the chances of that!

Sorry about the lateness of posting pics from yesterday. Good old internet problems has meant no access till now.

Went for a chase after work yesterday afternoon. Started off at the lookout halfway along the Tenterfield-Casino Road. Incredible views up there! Managed to get a nice base letting go with a barrage of CG's.

(http://sydneystormchasers.com/system/files/images/08-12-03-01jh.jpg.preview.JPG) (http://sydneystormchasers.com/system/files/images/08-12-03-01jh.jpg.JPG)

From there I headed east anticipating development closer to the coast. Sat at Lismore and watched two nice looking updrafts go up around North Casino/Bentley. Headed west and core punched the southern most cell of the two. 2 - 3cm hail and winds around 70 - 80km/h.

Headed home to Mcleans Ridges before hearing distant thunder. Jumped in the car and watched the same lightshow, MB, Roddy , Pato etc got. Some of the lightning was incredible. Such strong bolts piercing the valley floor below. I love watching lightning from up high!

Great photos!! Some of those CG look HUGE.

Apparently the Cape Byron Lighthouse got hit last night aswell

http://www.abc.net.au/news/stories/2008/12/04/2437450.htm

Quote
The lights have gone out at Cape Byron Lighthouse at the easternmost point of the Australian mainland.

The lighthouse's massive bulbs blew about 8:00pm last night as a spectacular electrical storm swept through the region.

Staff from the Australian Maritime Safety Authority say they believe that the lighthouse itself took a direct lightning strike.

Authority spokeswoman Tracey Jiggins says staff are on their way to fix the problem.

"The lantern controller has been damaged," she said.

"Until we get people onsite and do an assessment we're not sure of what other damage may or may not have been done but there haven't been any reports of damage to the lighthouse itself."

Ted Taylor with the Cape Byron Coastal Patrol says the lighthouse's 1,000-watt halogen lamps aren't working.

"The light's revolving. It's got two bulbs inside but it looks like they've blown," he said.

"We've got no computers or nothing up here too. So it's blown everything up here too.

"It's just a waiting game until maritime services come down and fix it up."

Action has kicked off with a vengeance this afternoon. Severe severe cells are lashing west of The Gold and Sunshine Coast hinterlands as well as Brisbane (and somewhat decent for northern parts!). Something big is coming towards my location, the thunder is very audible. The western sky is extremely dark and ominous looking.

It keeps hugging the ranges. Once it comes off them, it seems to hit a wall of some kind and the rain rates drop like buggery! It's spitting here now but it doesn't seem to know when to make its mind up ha!

I'm now contemplating whether I should disconnect or keep reading the forums for updates?

Hey guys i am from Ballina in the northern rivers. On the 3rd of December, we experienced just the outer part of those storms mainly a lot of lightning and light rain. I have a few pics over here and a video on my comp that i am trying to find out how to post it.

Post by: Steven on 07 December 2008, 01:12:07 PM
She's firing. Off the ranges seem like good triggering points as the humidity is insanely high (Logan had 86% with 30C dewpoint!). There was a strong cap present today which inhibited the development of storms locally, but we should see that changing later on (i.e more rain tonight with embedded cells). That cell nearest to me is putting out a fair bit of lightning and thunder but nothing photogenic.

I love all thos lightning shots from around your place Michael. You are blessed with that valley! I'd hate to live down there and be under attack like that.

James, your bolts looked rather skinny for a digicam and you got several on one frame which is impossible in daylight unless it's a multiple strike. Are you using a ND or polarizor filter to cut down your exposure? I've used one (ND) several times and found it does the same thing to the lightning unless it's really close and bright.

Regards Jeff.
Title: RE: NSW / QLD Severe Storms and Lightning: 2 - 8 Dec 2008
Post by: James on 08 December 2008, 03:37:54 AM
Your right about the multiple strikes Jeff. I was using a Canon 5D with a 24-205L lens with an aperture of 22 and exposure of 2 seconds at the start, increasing to 3 seconds as teh storm got closer and darkness started to creep in. I normally use a polarising filter when attempting daylight lightning shots however I left it at home that day so had no filters on at all.

As to why the strikes look skinny, I thought about that when looking at MB and Rod's images. Perhaps mine were taken earlier when there was more light around? I have noticed lightning can look a little skinny with plenty of light around. Having said that I drove over to MB's street as the storm hit and got one strike near his house which looked different to all the other ones ... I will try and upload it in the next day or two.

Some high based activity passed through the Northern Rivers later yesterday afternoon (6th Dec). The cells were quite lightning active at times.

Sunday December 7 2008

Perhaps a surprise packet for some - the Sydney area and the Central NSW are in for some storms. There is the possibility of at least marginal severity. The first lot of storms have already proceeded across western Sydney and mone cell is moving towards the northeast.

More cumulus developing to the southwest in the sunshine.

Interesting the current storm on the radar. Lots of rumbles in the sky but no lightning seen. The storm did a split just before reaching Parramatta and the right half died off, but the left hand one has headed off to Glenorie and is intensifying and up to red on the radar loop.

Nasty little severe warned storm NW of Brisbane at the moment as well.

QLD Bom have just noted two dangerous cells:

Quote
For people in parts of the MORETON BAY, DALBY, SUNSHINE COAST, SOMERSET and SOUTH BURNETT Council Areas.


Issued at 4:10 pm Sunday, 7 December 2008.


The Bureau of Meteorology warns that, at 4:05 pm, very dangerous thunderstorms were detected on weather radar near Beachmere, Bribie Island and northern Bribie Island. These thunderstorms are moving towards the east. Very dangerous thunderstorms are forecast to affect Deception Bay waters, northern Moreton Island, Comboyuro Point and waters off Bribie Island by 4:35 pm and the area west of Kingaroy, Tangalooma, Cape Moreton and the area southwest of Kingaroy by 5:05 pm.


Other severe thunderstorms were located near Mount Mee. They are forecast to affect Caboolture, Burpengary and Wamuran by 4:35 pm.


Destructive winds, very heavy rainfall, flash flooding and large hailstones are likely.

The same cell which was approaching Kingaroy on the earlier post is still going 2.5 hours later. Quite a compact and long-lived supercell.

Post by: JulianR on 08 December 2008, 03:59:56 PM
Gday All,

After umming and ahhing about which area to target today I decided to stick N of Brisbane, which GFS had taken a liking to. After spending a couple of hours watching some convection pulse through Yarraman, just after 3pm a cell which had been steady orange on radar exploded into a nice deep brown/black core, just to the W of Caboolture. Just sitting on the outskirts of the town, I could see Cg's in the distance with some really earth thundering solid thunder, which was encouraging at this stage as for most of the day the cells just looked very weak and pulsey.

About 7mins later, after the cell deepened in intensity, I could see a feature in the distance so drove further W of the town and caught a glimpse of a guster. Quick glance of the radar loop showed that the cell had lost its intensity slightly, and this was reflected in the guster looking a bit decayed as I drove a few mins further W down the road.

At this stage the propagation of this cell was favouring an E/SE trajectory, so the next nearest best clear unobstructed position was Bribie Island. By the time I had turned the car around and I was about to drive over the Bruce Highway overpass to Bribie Island Rd, I caught a glimpse of the guster from about 9mins ago which I thought was dying, but had exploded in its size and was literally chasing me E'wards.

At this point there were flashbangs directly overhead as the precip was starting to intensify and looking in the mirror it had shifted its path, sliding slightly south. The next best option was to find an open area as quickly as possible, and that was found by making a hasty right turn down a road which I had no idea where it lead to. All I have left to say is thank god I had GPS in the car or else id have been running around in circles, scrambling to find a way to a clearing.

Upon reaching the beach there were people out wading in the water, people walking the streets and kids playing on the road, all the while where were gunshot cg's flying out from the leading edge of the guster. I have never witnessed such sheer stupidity or ignorance from people with a severe storm like that bearing down upon them, literally seconds away from opening up. Once the guster was directly overhead, heavy heavy precip and wind gusts up to 100km/hr+ were experienced, followed by marble sized hail. A frightfully exhilarating experience I must say, but I did not feel safe at all outside of the vehicle taking shots prior to the guster moving over, due to the lightning flying everywhere. Anyway enjoy the pics!

Very nice shelf cloud structure with those Queensland storms - incredible!

Just for reporting's sake, the storm that began in southwestern Sydney and then proceeded to the Central Coast split and passed near Schofields approximately 1:30 to 2pm. We received some steady to heavy rain with large droplets at times but never intense rain - being just outside of the core. Here are some pictures of the developing and organising structure (I had to attend a family BBQ so could not chase - worst luck)...

I assume the Sydney one achieved warning status at some stage, though missed it as I saw the cancellation one. Maybe got 0.5mm here though the radar would have indicated more than that. Would have interesting to follow it to Glenorie and see what happened up there.

Julian, sounds like you had a nice chase up there even if the lightning got a bit close. But I agree, continuing to play on the beach as the lightning comes over is a worry. Have done a bolt years ago from a golf course when things started getting a but close (like the adjacent fairway). Seeing as we were on the 9th we declared that a par and bolted for the clubhouse!

Awesome cloud formations you had there with that one. Hope I catch some on my north coast trip next week.

A squall line tracked across the Sydney metro area between 3-4pm today (Monday).

Had to go to Rhodes to pick up some things which just happened to be at the right time. Despite more tropical style mid-level flow and Tasmanian sfc temperatures, there was a stiff moisture laden ENE wind to help the upper trough out, with gusts over 40km/h, effectively force-feeding this complex, which was not too shabby. Well, we'll take what we can get in Sydney this year!. The hybrid shelf / roll  cloud had some really dynamic motions, obviously in an environment where there was strong low-level vorticity. A pity I did not have my videocam on hand as it would make for some good timelapse, not to mentoin some strong CGs dropping out in front.

Phone pics from Rhodes Waterside precinct. In the first can see steam from the chimney stack being blown west and also note the stingers at cloud base which are indicative of strong moist storm inflow.

Not a bad wee storm  huh Dave  :)

  I found a place in Carlingford to take a few pix as it headed towards me  some good CG's and a good
number of buried CC's.
   I then continued up the road towards Dural and got hit with the gust front on Castle Hill Rd a bit prior to
the Old Nthrn Rd jnct. No hail where I was, but VERY heavy rain made for extreme driving conditions.
By the time I got to the Glenhaven area (prior to Dural) I had passed through the rain and storm.

Impressed by all the photos and comments!  What about those lightning images MB - did you notice how the surrounding ground lit up where the strike hits!  Awesome structure and is that roll cloud included in those storms Rodney?

Sounds like that area needed a bit of a bombardment and it delivered.  Great stuff everyone who posted :)

I could not take any photos as I was at work but the storm passed over Auburn between 3.30 and 4 pm and produced two distinct but heavy shower bursts but not allot of lightning. Observed shelf cloud and only light wind. The main feature was the rainfall from it.

Apparently I saw on some news items that hail was observed at Raymond Terrace (Not sure on the size) and Tocal (Hunter Valley) collected 28 mm in 10 minutes. Cessnock collected 36 mm.

In Sydney the heaviest falls were in suburbs anywhere between Blacktown to Fairfield to Bankstown, Strathfield and Parramatta regions such as:-

25 to 30 mm around Bankstown, 20 mm at Toongabbie, 12 to 15 mm around Auburn and 12 mm where I live. The storm weakened somewhat closer to the coast with only 1.6 mm falling at Observatory Hill, 2 mm at La Peruse and 4.4 mm at Bondi.

Some really nice pics there Julian.

As for today's Sydney squall line, had rumbling overhead at Chatswood about 3:30, then had to drive up to Hornsby. Quite heavy rain around Lindfield - almost thought it was about to hail but didn't). Then all clear after that. Looked fairly impressive on the radar and listening to the traffic reports had caused some local flooding at Silverwater, Parramatta and down near Milperra. Got 17mm here at Rydalmere.

Wednesday still forecast for storms even possibly morning ones, so might get a chance for a few shots as I head north towards Narrabri.

It's day's like today why I love chasing in Australia, chasing storms with no one else around in the middle of nowhere! Sure they're not a patch on our US cousins variety however they still pack some punch to get the adrenalin pumping.

GFS had been a little over the top at the start of the season however seemed to be back to normal the last few weeks. Today was a classic example of why I never look at an LI chart only. -2 to -3 LI's had been predicted over the Darling Downs this afternoon however after checking what Temp/DP combo GFS was using (25/17) it quickly became apparent that it was incorrect. MLAPS had temps hitting 29-30c around Goondiwindi with a DP between 16 - 18c. A quick adjustment of the GFS sounding gave a much better indicator of the potential on the Downs. LI's of between -5 to -6 and CAPE heading towards 2000, much better! A tongue of colder air at 500mb was progged to move across the region mid to late afternoon. Another plus.

I always love a good rain band in the morning over a target area as long as it clear by lunch. Today was timed to perfection with the main moisture plume and cloud clearing the region by lunch. WV imagery showed the dry air above had well and truly pushed across giving the updrafts that appeared around 1pm a lovely rock hard sharpness to them.

The temp had hit 29 and the DP on my kestrel was showing 18. I watched an isolated multicell develop to the east of Moree and noticed a small line developing to the west of Moree. The line didnt look great at first (lower DP of 14 would not have helped where it had developed) so I watched the Multicell for an hour or two.

  (http://sydneystormchasers.com/system/files/images/08-12-08-01jh.thumbnail.jpg) (http://sydneystormchasers.com/system/files/images/08-12-08-01jh.jpg) 

Finally it started to weaken and my attention now turned to the line behind.

  (http://sydneystormchasers.com/system/files/images/08-12-08-03jh.thumbnail.jpg) (http://sydneystormchasers.com/system/files/images/08-12-08-03jh.jpg) 

It was finally encroaching onto Goondiwindi with ample moisture now available. The bases lowered and the first shelf cloud of the day developed.

For the next few hours I kept ahead of the north-eastwards moving line as it crossed Goondi and onto Millmerran before finally calling off the chase at 6pm.

Lots of flash flooding and strong wind gusts however did not see any hail.

As a side note if the Downs was to get another rain event very shortly, there is the potential for some serious flooding to occur. All the creeks and causeways over the back roads were over flowing with water. Fields looked like lakes in places.

Hi,

Awesome shelf cloud structure Julian! Do you know for certain they are supercells? The tops look a little fuzzy and the updrafts separated? Was it confirmed by the Bureau? Of course, I have not seen radar. Obviously they did reach fair heights but the successive structure of the updrafts are more reminiscent of multicells. If you cannot quantify your claims, I will edit your post and change it to multicell.

Some storms in Sydney yesterday. Despite not checking the models, I took one look at the sky during the morning and warned Imelda about what was to come during the afternoon ie when I was not around. The storms occurred between 2 and 3pm! Some heavy falls around which was good enough to keep the grass green.

We have had 18.6mm from the previous storm and rain event and then 12mm from yesterday's event in Schofields.

Here a couple of pictures whilst on the way for a checkup for Imelda:) I guess more for reporting the event than anything else. Good to see moisture finally arrive in Sydney. We may be in for some storms as of now on.

Hi Jimmy,

The two cells in question were no doubt supercellular in my opinion. No#1 Cell once breaking the cap, had tops well over 40,000ft, and at the base of the updraft were two bell dome features, related to the classic type supercell. Cell No#2 did not sustain supercellular features unlike Cell No#1 and became slightly outflow dominant as you can probably see in my daytime CG shot. Michael Manning has some better contrasted photos of Cell No#1's features clearly showing that of a classic supercell. I was not aware that the BOM confirm supercells in their STWs? I have never come across the actual word being mentioned. The only way the BOM would have been able to confirm it would have been through a phone-through report from a spotter out in the field anyway.

Cheers,

Julian

Julian,

Thanks for your reply. Interesting to say that you are suggestign "without doubt". In my opinion, your pictures show separated updrafts which to me indicate that it was multicellular at least during the time you took your pictures. Nice updrafts of course but the heights of 40,000ft by no means define supercells. A supercell is a thunderstorm that has an updraft with persistent deep rotation (typically rotating for 20 minutes or more).

In terms of Michael Manning, the following photograph is the best I can refer to that you may be suggesting:

http://jeff.bsch.au.com/gallery2/main.php?g2_itemId=1058

The lower level structure is quite nice. Perhaps this was an interaction with a boundary. Nevertheless, it looks more like an LP. Very little precipitation is falling from the base of the main updraft. And then it seems to enter into a collapse mode rather quickly with rain falling through the base and cutting off the inflow. Perhaps the storm crossed a boundary to develop some nice features.

Regards,

Jimmy Deguara

The BoM do in fact issue warnings with enhanced wording to the effect "this is a dangerous storm" and I would think that this is used only when a mesocyclone is detected on doppler radar (and to that end is only used in detailed warnings for capital cities and surrounds). Since a mesocyclone cannot be seen by the human eye, BoM are unlikely to upgrade a warning on that basis as it is becomes far too subjective and, utimately, unreliable.

Hi Jimmy,

To better explain what I was referring to you before, I think you are a little confused with storm days. I am referring to the 3rd of December, not the 6th of December. Here is a picture taken from Michael Manning which clearly shows the structure in question:-

(http://michael.bsch.au.com/gallery2/d/12895-1/IMG_4655.jpg)

That feature is on the base of this updraft here:-

(http://julian.bsch.au.com/pics/031208/031208_001_thumb.jpg)

There was some time to develop in between both pictures, but you can see clearly in the first picture the feature which I have been trying to explain.

Cheers,

Julian

They often make that statement for Sydney and they don't have a doppler radar here yet (unless it is a secret one). I would say they can usually predict from the behaviour we look for - movement different from other storms in the area, the intensity in the centre. And of course storm spotter observations when you see the text "5cm hail reported at xxx".

Sydney was the second Australian city to have Doppler radar. Darwin was first -- it was used in some of the many studies up there. During Sydney 2000, we had two Dopplers covering Sydney I believe (having borrowed Darwin's) -- all from memory, correct me if I am wrong.

The dangerous storm text does not necessarily infer a supercell, it has also been used for multicells....its purely when they have a spotter report or get such a radar signal that it recieves this statement....usually the prior



Who told you this?

So everyone knows who reads this topic. The Kurnell Radar is in fact a Doppler Radar.

What is with the orange coluration in that image? Were you using a coloured ND grad?

Hi John,

Your comments about the VDS not just being used for supercells is interesting.  I'm wondering if this changes from state to state?  I've only seen the VDS comment for Sydney and Brisbane regions, and anytime it's been used it's always been a supercell (and a well structured one at that).  From my observations, a 'VDS' is used for supercells, but not all supercells are given a 'VDS.'

There are many times when the warnings have listed a spotter (or public) report but no VDS has been given.

I'll go one step further to say, from observations, the 'VDS' is used when significant low level rotation is being detected in the storm by doppler (ie, it's the Bureau way of saying 'this storm may produce a tornado').  But I know of two storms this year to buck this trend a little...

And yep...the Kurnell radar is a doppler (implemented for the Olympic games).

I was aware that Kurnell was a doppler radar, but it isn't easy to find on the BoM site except through a google search and doesn't have the windfinding features available online. Not sure why as Brisbane and Adelaide both have links to their new dopplers and the original ones. However we seem to be digressing into what makes the bureau issue a "this is a severe storm" message.

Which is fine, but probably easier to ask someone there than speculate.

Fairly long lived cell, that showed up some mesocyclone rotation on the Brisbane Doppler :- http://www.theweatherchaser.com/radar-loop/IDR66I-brisbane/2008-12-06-06/2008-12-06-09 (http://www.theweatherchaser.com/radar-loop/IDR66I-brisbane/2008-12-06-06/2008-12-06-09)
I've attached a few pics that show storms structure from over the location of Kilcoy through to Beerwah app.
