Again more storms are forecast in a rather hot and humid weekend ahead, what will bring on Friday, Saturday, Sunday and Monday? Who knows, but all I know is if we don't get more moisture things look marginal so it will be rather frustrating, so let's discuss this storm potential!
-
Hi Steven,
I'm going to have a more detailed look at things late tonight when I get home and will post some thoughts on here. Interesting to note that the DP's around SEQ have been pretty low today with some fairly warm temperatures. However, in the last 30 minutes, I think the SE'ly change has finally made it to Brisbane as I can now see low level Cu moving relatively rapidly inland (from the SE). I'm hoping this change can push 100-150km inland over night tonight (might be a bit hopeful but we'll see) as this would inject a nice burst a moisture onto the ranges for tomorrow.
More thoughts later.

There is good low level moisture over the region this morning thanks to the weak southerly change yesterday afternoon. Winds are northerly here with the dewpoint sitting on 15.
Last night's Brisbane sounding shows quite a strong 850 hPa inversion, and another at about 550 hPa. Will be interesting to see how this changes during today.
-
Hi all,
In response to the two points Michael raised, I think the 550mb inversion will weaken as the upper trough approaches this afternoon and the 850mb inversion - i hope this hangs around as it would keep convection nice and isolated with any luck. But on that, you'd then need to look for areas where this inversion (cap) can be broken - the ranges and along the trough.
Today has looked better with each model run. Not sure if anyone has noticed (maybe its just me) but the models have really not been that great in forecasting the last few events until the morning of the event. Makes it tough to make a proper forecast target a few days/the night before.
Shear isn't great in the 600-500mb layer today based on forecast soundings but the latest LAPS run shows a great upper trough pushing into SEQ today. Upper troughs always make me happy . Apart from the 600-500mb layer, shear is pretty nice. The lowest 1-1.5km are generally N to NE in the 10-15knt range and then westerly above that, getting up to 25knts at 700mb. Shear at the anvil level is around 50knts which isn't too bad either. Instability...well with the upper trough pushing in and dropping 500mb temps down to -14 to -16C range (-14C over Wide Bay and -16C over the BR's), combined with say 30/15 gives some pretty tasty instability indicies with CAPE approaching 1600j/kg and LI's in the -7C range. Certainly nothing to shy away from. (Not totally dissimilar set up to Nov 8 last year).
Without going into too much detail, I think I'd probably head out to somewhere like Marburg. My preferred are of choice is probably around Yarraman - Nanango (maybe a bit further N) but to keep the southern option open, Marburg is a good starting point as you can shoot S to Boonah if things fire down in that region.
Looks quite unstable for the next few days too but again its hard to pick a target as the models don't appear to have a decisive handle on the situation. Mid/upper level moisture may come in to play over the weekend.

Ok - three words...VERY NICE SOUNDING.
Great cap - breakable - but strong enough to keep convection isolated. Shear is lacking as has been mentioned but there will be some very nice storms out there later this afternoon (wouldn't expect much before 3pm). Sat pic is nice - shows where the moisture is at the moment.
I think I've seen enough now to commit to N of the Warrego Hwy. I reckon you can squeeze another 1C (possibly 2C) of moisture by being further N but the upper level temps and shear are largely indifferent. What does this mean? Simply more instability. I'm not discounting the southern option (ie BR's) - I think that area will see a storm or two and the area is actually more favourable for chasing. But if I was chasing today, I'd be trying to find the biggest, nastiest storm I could find which I think will be over the Brisbane Valley area.
With the shear being somewhat slack, I wouldn't expect anything to make it to the coast until quite late (6pm).
Fun times for those chasing today!! Enjoy!
Macca
PS: Watch out for your windscreens today folks!!!

Gee looks quite nice. I like the quite sharp drop-off in temperature with height through the mid-levels, and also the drying above the boundary layer airmass. IMO, it's a borderline situation for an HP today since although the deep layer shear is somewhat weak, the surface to 850 flow veers nicely in the early evening......and updrafts should be quite strong. Suppose this will be dependent on if/how early things fire up and, thereafter, the extent to which cold pooling courtesy of the weak mid-level flow facilitates more widespread stuff.
-
I could sense that humidity just pour in last night, although hovering at 21C it was rather uncomfortable to sleep, I do have a good feeling about this one, largely because of the soundings, but I don't have expert knowledge what will happen ahead but by going by instinct I can almost feel large hail is coming. With dew points at around 15 development is likely late, however interestingly at my location it's at 19.
-
I long for that kind of air to invade us down here!
Little cell has developed NW of Mt Perry and is stationary. Some strikes recorded.
-
Good luck all. From reading the posts the sounding surely is sweet. 21c overnight would be nice at the moment here, it's 26! Look forward to seeing the posts and pics.
Mike
-
Arrrggg!! nothing whatsoever tonight, it has mainly been confined to the Capracornia region and tomorrow doesn't look like storms are likely either, I am not to sure what Sunday will bring but Sunday and Monday are our best chances at this stage.
-
Looks reasonable for storms in the coastal regions between about the Tweed and up today. The air here has a lot more moisture in it than yesterday, with the DP around 17 and a NNE breeze atm. The shear profile is very good near the coast. We have an upper trough but the mid level lapse rate does not appear to be as nice as Friday in the GFS forecast.
The surface temp and dew point were not sufficient to get through the cap yesterday - which was pretty strong yesterday:

I also thought there was too much dry air above 870 hPa, but welcome feedback about that.

-
The latest Bris sounding is very nice so long as the cap can break. There's a LOT of instability above 900 hPa

Bit of activity inland NSW right now - hopefully someone can report more about those later.

Hi guys,
Temps are up today, currently 34º and it's fairly humid, I apologise I cant give you exact numbers as our local "weather station" or "thermometer box and tin can with a ruler in it" leaves something to be desired to say the least lol? I surely need to invest in a good barometer set-up asap! We have a covering of what seems to be high, wide spread cirro-cumulus that seems visible on the latest sat pics so I would imagine the temps may increase once it has passed and might reach 36 or 37º.
A few small cells have passed through the Broken Hill area and looks like some activity around Orange. So it'll be interesting to see how the afternoon progresses? Best of luck to all that are willing to chase today!
Regards,
Shauno

things looked good somewhere lol i got these snaps from coolangatta( on top of the big hill near the beach looking towards the airport)

Hi all,
Saturday 6th October 2007
Had a nice storm chase on my way up to Bryan's 21st.
Started off with a slow moving cell that formed southwest of Casino and tracked slightly south of east. This had great updrafts but was not very high topped until later when it got close to the coast. It was pretty obvious it was very dry west of this activity, with the only other area of interest on the Border Ranges.
This was my target anyway, so headed to Kyogle then the Lions Road over the Border Ranges. The timing turned out very nice as the main storm of the day was now developing.

(http://australiasevereweather.com/temp/forum/thumbs/2007100602.jpg) (http://australiasevereweather.com/temp/forum/photos/2007100602.jpg) 3.37
By the time I had reached the NSW/QLD border the storm had really taken off. The updrafts were exploding virtually overhead. The base was quite high and was not producing much precipitation (that I could see). Thunder was booming in the valley though I didn't see any lightning.

I watched development here for 10 mins or so before heading towards Rathdowney. The hills get in the way a bit, but not for long.
I was amazed at the power of the main updraft - it sure tapped into all that CAPE !

It took on a bit of a corkscrew appearance briefly but the whole storm weakened soon after this.

Wonderful shots there Michael and Slavegirl, if only I had the chance to use my camera for one of these.

Hi all,
Looks like the afternoon is taking off over SE QLD and NE NSW! The lightning tracker looks unreal! We missed out over this way, getting just a dark-ish grey covering of mid level cumulus and a small amount of virga here and there.
Lets hope Wed. and Thurs. bring a repeat of this system but start off a little further inland (around Tibooburra would be great) so we get something out this way, lord knows, we sure need it (coughs from all the dust lol).
Cheers guys, cant wait to see the photographic outcome of all these storms your all getting over the eastern parts!
Stunning shots Michael, almost looks like a small lowering at the outflow base of that absolutely massive tower!
Take care.

its looking good from where i am in carrara at the moment, lightning activity has just picked up no thunder as yet so still a while away but there is definantly a nice storm moving in our way yay!!! :D
-
Hope you get some nice shots !
A couple of lightning pics from here Sunday 7th October 2007. Has been quite active with lightning since about 4pm.

Hello
Michael, they are fantastic photos. Impressive storm structure you captured.
I was analysing the Mt Stapylton radar (Brisbane) and a line of 6 storm cells were just west of the Gold Coast between 7.00 pm to 7.20 pm - 7/10/07. I noted that there was substantial weakening of several cells as they approached the coastal region. The northern most cell being the strongest cell had been warned as a severe thunderstorm at the time I was looking capable of producing mainly heavy rain and damaging wind.
This is the strongest storm system that I have seen this season to date.

in this one an anvil crawler happened above the view of the camera but if you look closely in the top of the pic ( right in the middle) you can just make out the bottom of it
-
-- 08/10 --
The Brisbane sounding looks very good again, and even though 850 is not exactly too cool, I get the feeling that things might go off too easily, which of course would not be good for discrete supercells. The longer initiation holds off the better, as there will be some tremendous instability around with daytime heating this afternoon. The flow is somewhat unidirectional with pretty decent speed shear, and assuming more isolated updrafts prevail at the onset, this would tend to favour splitting storms. Still, it could get very interesting if one of these early dominant storms can tap into any surface wind changes later this afternoon in combination with that strong instability.
There's a fairly 'charged' storm cluster approaching the Grafton-Coffs region at the moment, and a warning out. Spring has well and truly sprung !
Edit: another cluster going through the same area now (12:40) and a cell developing just south of Inverell. Definitely evolving nicely for areas further north.
-
Inverell cell is now cranking along very nicely and is heading towards Glen Innes.

For people in the
NORTHERN RIVERS,
NORTHERN TABLELANDS and parts of the
MID NORTH COAST and
NORTH WEST SLOPES Forecast Districts.
Issued at 2:05 pm Monday, 8 October 2007.
Severe thunderstorms are likely to produce destructive winds and large hailstones in the warning area over the next
several hours. Locations which may be affected include Lismore, Grafton, Coffs Harbour, Armidale, Tenterfield, Glen Innes
and Inverell. Some of the largest thunderstorms are showing the potential of producing giant hail.
Just prior to 2pm Hail to at least 4cm and wind gusts of about 90km/hr were reported in a thunderstorm at Glen Innes.
-----
heading out shortly.
-
Better watch out Michael those echos look very nasty. Also what is with the low cloud on the webcams? looks rather freaky!
-
Really, very impressive on Grafton radar. Almost definitely several HPs ongoing and in fact there appears to be a good meso on the storm due south of Nimbin at 16:12EST (Mt Stapylton scan). I suspected quite a few storms would fire up given the weakish cap however they are all quite happily surviving in close proximity.
-
Appears to be an intense storm scale rotation on the storm west of Kyogle!!
-
These pics were taken by Jason in the South Lismore area this afternoon - Monday 8th October 2007. Lovely 5cm hailstones !!

Hey guys and girls this is my first post here so go easy on me. the pics above are from me, michael kindly posted them for me.i did a local chase round my house(LOL) in south lismore.the first part of the storm dropped maybe 5cent pieces of hail then it rained for 5mins or so then i heard the telltale sound of larger hail hitting the tin roofs in my neighbourhood. it wasn't long before the larger bits started coming down. so i ducked out quickly and grabbed the bigger stones. i must stress though that the larger stones were fairly isolated with most of the stuff around the 2-3cm mark. the third picture is of the storm that was headed towards coolangatta at around 5pm. certainly an interesting arvo of storms given the ideal setup.
-
LOL the band approached us at 7:00pm and was okay for about 5 to 10 minutes then it just fizzled into some lightning and thunder, very disappointing for us, glad to see down south copped a beating and a good lightshow, I doubt any further development for tonight.
-
Well heres some pics from Coffs today. The tally was 5 storms for the day!

Had a brief chase yesterday afternoon (Mon 8th Oct) with my daughter Katrina as work restricted me somewhat. So many large cells, anvil rain and then stratus racing into the huge storms made photography quite difficult, but it was awesome being amongst it. Random powerful CGs hitting nearby then blinding torrential rain and hail from the cell near Coraki were a lot of fun! Stones were 2cm there - about the same size as what fell at home from another storm.

Hi guys,
All the photos are great!
I'll put in my two cents worth as we had 5 small, totally unexpected, LP cells sneak through very early this morning. The first came through moving typically W to E at 12:04am along with two others, one to our N and one to the SE around 30k's away (from what I could gather from the lightning/thunder timing). At 1:45am two more rather larger cells moved through. I could see a nice anvil shield overhead clearly on the first with each decent lightning strike (which were all fast non-staccato bolts). The second hovered out to the SW but had great overshooting tower structure visible again from lightning flashes. By 2:06am the cooling atmosphere switch was flicked and all lightning had ceased totally.
I couldn't manage a shot, everywhere I pointed the camera, it would hit behind me! I ended up with the dreaded "black photo" syndrome, but it was definitely worth watching the show!
No real rain to report as far as mm, maybe a 'drops/per square metre' measurement might be more accurate? lol
This week should be interesting! It is great to finally see some good activity and top storm structure, hail and supercell photos!
Kindest regards.
Shauno

Wow. Great posts everyone and a very intense storm by the looks of all the lightning and hail! How are you guys getting all those daytime lightning shots so easily? You must be using a repetative shots or keeping it open for 10 second periods? I still can't get photos like that!
Mike
-
saw a beautiful storm on the way to boondall will post my vids of the lightning as soon as i can! the videos are of the storm just as we were crossing the gateway bridge such an awesome veiw of the storm! By the time we got to boondall the storm was close by and had awesome crawlers and cg's but the rain and concert times prevented me from getting any pics at all, just the 2 video's. It must have looked funny to see me hanging out the car window with a camera filming n the gateway lol
-
Oh my... what a busy few days for the NSW North Coast / SE Qld!
A set of massive supercells have gone through the Lismore area over the last few hours. The latest Severe thunderstorm Warning from the BoM says:
Lismore has been impacted by a very severe thunderstorm with giant hail the size of tennis balls and heavy rain. 20c piece hail was also reported at Grafton.
Sounds even better than yesterday's effort.
I can't wait to hear the reports from Michael B and others in that area!!
-
Just speaking to my brothers fiance (from Lismore) she said:
just talked to my sister, just about every house in there street has smashed windows & that including theirs
-
Lismore Hailstorm 1.45pm 9th October 2007. Yes - the car has some fresh dents !
The Lismore CBD and South Lismore have really copped it. So many smashed up cars, broken windows and windscreens, and the leaf litter - everywhere. The roof and windows on the church is broken - the one near the court house.
I got hit by 6cm stones with violent winds - absolutely incredible, a second storm 1 hour later dropped 2cm stones. Very heavy rain too with flash flooding.

I am moving back from Adelaide to Sydney in 2 weeks so looking forward to some better quality storms. But my girlfriend on the North Coast (Woolgoolga) has been telling me how good some of the storms have been there. Only problem is she is suffering the after effects of a strike on Sunday afternoon, she was inside the house near the front door when a bolt hit the verandah. She felt like someone had hit her arm with a baseball bat and her daughter got knocked off her feet. Obviously a bit of ground effect happening there. They have both been feeling a bit run down since.
Nice photos in this thread too guys.
-
Well i've just finished cleaning up the mess inside my house.Glass everywhere, leaves and hail. i love storms but that scared the crap out of me. i've got 5 windows with holes in them with 3 others cracked. i heard an unconfirmed report of roof damage(hail or wind?) to 30 houses in the lismore heights/goonellabah region. not sure of the validity of this but wouldn't be surprised. just about every house in my street has windows smashed( i live in south lismore). if i had to guess i'd say the hail was up to 5-6cm in places with most of it around the 2-4cm mark. just saw my inlaws car, its a virtual write off every panel looks like has it been used for golf practice. anyway thats my experience of the day. it will be a day i won't forget in a hurry. just hope that everyone in lismore and surrounds is ok
-
Beautiful storm,
Had a few rumbles in the morning around 11:00 and then the nice cell on the radar around 1:00pm East of Drake moving SE could see active Cg's in the West around 2:00 with deep mammatus and the gustfront came in around 3:00 from towards Evans Head bringing 55km/hr variable winds and got 38mm with no hail more storms forecasted for the rest of the week...
-
haha, I was out having lunch here in Sydney at the same time and the sky could not have been anymore different! Very impressive shots of the base Michael and quintessential north coast violent hp structure. Almost all of the pics suggest that the base is undercut, although, interestingly, the last pic shows a nice wall cloud having taken shape. Anything you can report on w/r to the storm's evolution at around this time? (as in what you could see at the time).
-
Very nice storm. Great work Michael! I saw a brief report on the news but I'm sure they barely scratched the surface of how much damage must have occurred.
David C, could you please elaborate a little on your comment above: I thought the whole big circular lowering, present in all photos, was the wall cloud? Also I'm not sure what 'undercut' means? Thanks!
-
Hi all,
Now thats what I call a storm! I hope nobody in Lismore was hurt and everyone was insured to some extent! You've set an amazing precedent to follow with those shots Michael (some of the best shelf structure I've ever seen!) and I hope you escaped unscathed from taking those unreal hail photos! Was there much lightning around? I'd imagine there was by the look of it!
I heard the temps dropped from 30º to 15º! If thats correct than it's no wonder the hail was so large!
Cheers.
Shauno

How are you guys getting all those daytime lightning shots so easily? You must be using a repetative shots or keeping it open for 10 second periods? I still can't get photos like that!
Mike
I can't speak for Kane on his shots at Coffs, but in low light I use high F-stops and aperture priority to get a second or two out of an exposure and get lucky with a bolt occurring during that time. Still means lots of deleting !
EDIT - Shauno - not anywhere near as much lightning yesterday compared to Monday's storms - not sure why....

This afternoon looks like a chance for us westies. You could be on today Shaun :-)
18z GFS run has lifted indexs below -5 all the way from near Mudgee to well beyond the QLD border. Dropping below -7 in places. CAPE is mostly to the north. Shear seems a bit ordinary though.
Measured surface dewpoints are better than they have been of late but not fantastic, currently around 10C. BOM are calling it "isolated thunderstorms possible over a large portion of inland NSW today and tonight ahead of it but with little rainfall expected".
Probably the best setup we've had so far this season. Camera's charged, pulse rate's up, fingers crossed.
-
No further storms here since early evening yesterday.
The SES have had over 400 call outs for assistance in Lismore. Apparently 17 people were injured by the hail.
Weather data for Tuesday 9th October 2007
Grafton 128km radar (http://australiasevereweather.com/storm_news/2007/radar/20071009/grafton128.htm)
The Brisbane BoM did a special 04z sounding again - pretty impressive !

I suspect the lagging SE change into the Northern Rivers yesterday helped the wind profile even more.

Clouds building up here in Armidale. Very likely to get a storm or two this afternoon.
Would you believe my car, which received hail dents from the hailstorm in Armidale on December 21st last year, only just went in to the smash repairers this week to have the dents taken out? There was a long waiting list. ::)

Hi guys,
EDIT - Shauno - not anywhere near as much lightning yesterday compared to Monday's storms - not sure why....
MB
Thanks Michael, it does seem weird, it has the look of a storm where you'd expect CG to be firing out in front of the shelf everywhere? But I'd be happy just to have the shots you took, they still blow me away!
I hope there were no real serious injuries from the hail to those 17people, and they all recover fast! Houses and property can be rebuilt, people can't.
This afternoon looks like a chance for us westies. You could be on today Shaun :-)
Hi David, it's looking VERY good at the moment, temps at 34.6º and the humidity is the highest I've felt so far at 53%. We have a cover of mid - high level cloud (visible on the sat pics) and a light ESE at 11km p/h. The DP is a 14.4.
I have the radio on waiting for the familiar lightning static. It's a faster warning for me than the lightning tracker lol.
Cheers guys, (I have the camera, tripod and handheld UHF ready to roll at a moments notice!) :)

Mike I use the same technique as Michael and also the rapid shot sequence + a little bit of luck for day time lightning.

Clouds building up here in Armidale. Very likely to get a storm or two this afternoon.
I just looked out myself, very excitedly. The do seem to be building up. I'll be keeping my fingers crossed.
Here in Armidale we didn't quite have anything like what was experienced on the coast. We've had a few cells pass. One passed at 4am on Monday morning, leaving 2mm of rain at our place in the North, but mostly light and noise. Others passed a little bit earlier, but I wasn't awake :( . We also had some action on Monday night. One cell left a recording of 80km/h gusts at Armidale airport. The rain was blown half-way up our front door, which is behind a roofed-porch.
There was a small storm sitting off in the distance later on that evening, just after dark. It had frequent lightning (but no thunder). I could see there was a cloud there, with the last light of the setting sun, but it just looked like a blob. When there was a flash of lightning, however, the definition in the cloud was shown up. It had a nice shape
I suppose our real excitement, though, was the hailstorm last year in December.

I have Lot of storm reports since last week. Few are on my website but last few days thunderstorms aren't up yet.
Sadly no hail in here at Ballina since! Just had 4 wild storms yesterday with 23.7mm of rain. Total rainfall for Oct is 47.8mm.
Nice 85km/hr wind gusts here yesterday afternoon. My dad also have photos of hail storm yesterday, his damage to car and his
place too. No trees left over at home. It was like some mad supercell and it was on Ballina's path!
Here the few reports on here: http://www.freewebs.com/stormshunters07-08/
More reports will come up during the weekend when i am on the break and even no storms so i can have time doing it.
Note that there nice cgs photograph i ever taken before! That was on Monday 7th.
Looking forward to today's and tomorrow's severe storms, hopefully hail here at Ballina this time!
Cheers Matt. :)

Nice photos everyone in celebration of a classic start to the severe weather season along the border region!
It continues - there is a left-moving cell some 150km west of 'Gundy' - I would say it is a nice quite isolated supercell - nice echo structure. Anyone who goes back through the archives, check Moree radar, 256km, starting around 5:50UTC and loop in through.
-
Fantastic shots everybody!!! keep them coming, this has got to be the most incredible storm event since last November!! Sorry to hear your car getting damaged Michael, these things happen and are unfortunate.
Anyhow last night, a storm front came over at around 6:50pm, with very loud thunder and frequent lightning, it went through in about 20 minutes, and while we missed out on the most severe part of the storm a bit further north trees were brought down on power lines which cut power to several areas. Another line went through today at around midday with loud thunder, but thats was it.

Hello
Fantastic photos. I am impressed with the photos and the Lismore supercell looks spectacular and ominous.
Monday afternoon I was following the storm events in northern NSW. While I was watching what was happening in Casino, I was following earlier reports of a separate thunderstorm cell that went through Glenn Innes earlier that afternoon. Did anyone capture anything of that storm? Apparently there were reports of a strong thunderstorm in that town that dropped hail up to 5 cm in diameter in or close to town and residents were cleaning up damage.
It seems that these storms initiated on the northern Tablelands.
I was watching the BOM alerts at 4.30 pm Monday and there was a warning of 6 cm hail from a storm cell close to Casino. Another storm cell to the north had a warning for large hail in it too.
This is the first time I have seen a warning issued by the BOM for hail this size (Being 6 cm).

Great pics from people in this thread.
I have been in Singapore for the past week - MB's photos from the border ranges cell with that single explosive pulse are amazing. I really enjoyed the discussion leading up to the event. David - I also had my eye on that storm west of Gundy. Shame those storms don't seem to be there when I am. Hoping for a few more in Central NSW tomorrow.
-
Hi Harley and all,
The BoM issued very specific warnings on Tuesday as well - mentioning hail size again like Monday.
Ben has posted some pics of the Glen Innes storm - check the top of this page:
http://forum.weatherzone.com.au/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=17;t=000311;p=10
It was the same storm we ended up in at Coraki so it sure travelled a long way and amazing it held together on the Northern Rivers considering how many other storms developed near it.

Hi all,
I thought I'd share a photo with you from last night. We had a small cell form to the East of us here and move out towards Collerenabri at 8:15pm. It was only sparsely active and I was lucky enough to catch this shot. We also sat out on a high ridge located NE of town around 9:30pm and watched the monster storms pass through the Hebel/Mungindi region, what a show! Couldn't get shots from here as it was just too distant? Even though the storms were 50+k's away, the atmosphere was so highly charged at that point that when I lifted my small nylon umbrella to face hight and open it, bright, 1inch blue static/plasma bolts would emminate and buzz from the metal tips of the outer edge and remain there for the duration, only to weaken once I moved my hand towards them but return to full strength after I took my hand away! We've never had that happen or seen anything like it before, it was strange and amazing to see! I will definitely try to photograph it if I see it happen again!

Static discharges from your umbrella? That's amazing. You sure you weren't in the line of fire for a step-leader! I'd like to hear more on that if you would not mind Shaun, that's pretty interesting and from anyone else who has experienced this - so much so I've posted a new thread in the general discussion area to continue this topic.
Mike

Fantasic photo Shaun. We had nothing in Narrabri, but I was certainly wishing I was up around Dirranbandi/Mungindi to watch the big left-mover that was visible on the RADAR.

Back at home the webcams sure got a show too ! Well worthwhile downloading these AVIs

Hi all, been a while since I got online. I had a look at Michael's webcams and noticed an interesting visitor in one frame. I apologise if it's been mentioned already as I havent got time to scan the threads to check, but have a look at the first cam and pause it at 3.27 - I assume its a kite or hang-glider but who knows!!!??? :)
Brad.
-
Hello Brad,
It looks like a kite to me! There's nobody hanging underneath for it to be a hang glider. There is no fuselage so it isn't an aircraft (besides it is too close and low). ...and it definitely is not a UFO, just an ordinary terrestrial kite!
Regards,
Geoff

Hi all!!!
What an event, and so many awesome photos by everyone!!! I chased NE NSW on the Monday but had to head home Tuesday due to work and missed that Lismore ripper unfortunately. However I got a nice supercell at Glen Innes that had a wall cloud with some rotation, along with 5cm hail along the way. Along with this was 5 other storms!!! Anyway I will have a report up for this shortly.. till then heres a few piccies.

Hi Ben,
Great shots! That last shot of the RFB is stunning, don't get to see those everyday, thats for sure! It looked like a pretty nice cell on the radar images.
I'm eager to read your chase report! :)
Cheers.

Hi,
Here is a You Tube video of the 9th October storm (taken from Tyagarah north of Byron Bay):

Welcome back JD, could you send some of that boring vertical convection to your NW thanks? :) NSW and QLD certainly have seen some fantastic supercells cause significant havoc around the areas. You've gotta love those troughs that push through!

Some more photos from the Lismore Hailstorm on 9th October 2007
The first photos are by Jason of South Lismore (forum member Pato) - who also copped some large hailstones the day before - see earlier in this thread. He had 10 windows smashed by the hail, and even paint chipped off freshly painted exterior surfaces.

Was there any rotation with that supercell Ben as depicted in your last photo? Looks like there is from the centre of the cloud base no?
-
saw a beautiful storm on the way to Boondall will post my vids of the lightning as soon as i can! the videos are of the storm just as we were crossing the gateway bridge such an awesome view of the storm! By the time we got to Boondall the storm was close by and had awesome crawlers and cg's but the rain and concert times prevented me from getting any pics at all, just the 2 video's. It must have looked funny to see me hanging out the car window with a camera filming n the gateway lol
Sorry for the lateness of my post but here is the vid (http://vid216.photobucket.com/albums/cc115/slavegirl23/stormthenightofthemarilynmansonconc.flv) i said i would try to get on here of the storm that hit just near Boondall.
(There is a very nice crawler right near the end of the clip) Sorry if the quality isn't all that great the vid was shot using a digital camera, not a vid camera so it gets grainy when it is viewed zoomed in. Enjoy.

Hi,
I particularly like the one very nice anvil crawler in that clip nearing the end. Great stuff - good anvil crawlers in Australia are not particularly common.
Regards,
Jimmy Deguara
-
Thanks Jimmy,
The particular storm i filmed hit right near Boondall (it was good timing it hit just as we pulled into the carpark at the bris entertainment centre) This storm was producing alot of anvil crawlers the majority being alot bigger than the one at the end of the vid clip. I couldnt get any film of them though unfortunantly as i wasn't allowed to take my camera in with me and due to the rain i wasnt about to stand in a deluge to get pics lol i noticed that while in the car filming the lightning appeared orange and pink but when the storm actually hit the lightning was a purple/blue colour, any particular reason as to why the colours seem to change? My apologies if it seems like a silly question but being a newbie to all of this the only way to get answers is to ask questions.
cheers Karina
-
Karina,
Distant lightning is often orangey and reddish in colour perhaps due to the haze and dust that can be kicked up at that time of the year. The city lights reflecting on the cloud bases can also impact colouration.
Overhead, you are looking through a different atmosphere so differeing wavelengths filter through. This is just a basic way of looking at it but if there are other more technically minded people with some better explanations I would certainly like your thoughts posted here.

Jimmy Deguara

Hi guys,
Was just browsing around on the internet and came across this particular image. Does it look familiar to anyone who chased on the 8th October 2007?

No, I was further south. It must be the one that dropped isolated large hail on South Lismore (including Jason's place).
Goolmangar is about 10ks NNW of Lismore.
