Looks like there should be some storm activity over wide areas the next few days though the models are chopping and changing with regards to a rain event early next week.
GFS is progging significant instability over parts of inland NSW Thursday and Friday but is there enough moisture? Shear is pretty terrible over Northern NSW.
Just hope this system can deliver SOME RAIN AT MY PLACE - bloody ridiculous dry spell drags on.

It is dry isn’t it? I remember last year on my birthday we had a pretty severe set of storms this year is the complete opposite.

Tomorrow looks like a good possibilty for NSW, as for QLD at this stage maybe a few showers Sunday - Monday.
NT is starting to fire up to from a few reports I have read.
happy chasing

TV Weather was predicting a bit of rain for Sydney on Sunday. Like others have seen the CAPE/LI predictions a bit earlier this week showing tomorrow and Friday could develop a bit down towards Canberra etc. Not sure how the models are looking now though. At least no storms predicted for Brisbane tomorrow night with the day trip there - don't want another delayed flight!

Hi,
I am not so happy with the performance of GFS as with the past few seasons. Moisture is being more than significantly over estimated for the inland and possibly due to a faulty weather station reading entering the model data. Even moisture along the coast is not that high and perhaps lacks the depth though it may be sufficient for activity.
So perhaps more coastal rain and storms are likely once again with extremely dry conditions inland more likely Thursday to Saturday. Beyond this period, perhaps southern Qld wilol have low probabilities of high based storms.
Regards,
Jimmy Deguara

Well there are a few thunderstorms firing up in the southwest and they look rather stationary. Below is an instability map for Sunday from BSCH looks like there may be some costal action. There is also a GFS.

Morning everyone
Currently in Armidale. We had light thunder shower yesterday afternoon before 5pm that created a large cell near Dorrigo after it formed over us. Nothing much after that at all.
Possibly today may be good ones for NT's. Only nice and warm at the moment with some breeze which is better than at this hour yesterday! Some altocumulus in high levels appearing in skies pretty much as sunny skies. However i have not looked in the models and soundings for today.
Cheers

I agree with Jimmy - it is becoming very very irritating!! They should really get it sorted out. Yesterday moisture depth was the issue, and today looks the same at least as far north as the Hunter. The MNC/NT should get something but then again wind shear is also weaker up that way so storms probably won't reach the coast. Disappointing system!

Armidale's landscape becoming more resistant to thunderstorms already at this hour. Nice cells playing around on Thunderbolts Way and Gwydir Hwy near Glen Innes. Theres a cell could form just southwest of the airport here at UNE. I can see nice pulse fresh updraft coming from down the hill. Trees are a little annoying here because the university is located in semi bush area!

TOP PRIORITY FOR IMMEDIATE BROADCAST
SEVERE THUNDERSTORM WARNING
for LARGE HAILSTONES, FLASH FLOODING and DAMAGING WIND
For people in
western parts of the MID NORTH COAST and
eastern parts of the NORTHERN TABLELANDS Forecast Districts.
Issued at 1:14 pm Friday, 23 October 2009.
Severe thunderstorms are likely to produce large hailstones, very heavy rainfall, flash flooding and damaging winds in the warning area over the next several hours. Locations which may be affected include Jackadgery, Dorrigo and Ebor.

Looking better here already. Lot of CB towers with fewer Cj's. Theres alot of breeding cells just south of Armidale with severe cells northeast of it. Getting interesting here at UNE. Might try to get some photos!

Evening everyone. Here my first storm report from Armidale.
The day started out very mild and a little humid as the day comes it got drier and warmer up to 27/10 (Armidale-UNE obs). There were alot of convection in skies that has started after 11am and brew into weak thunderstorms over Thunderbolts and New England Nat Park.
As the day eventuated, first severe thunderstorm warning issued for that area. During lunch time there were numerous shower cells formed over us with occasional thunder booms. Then around 5pm a larger thunderstorm fired up in southwest near Uralla Plains and marched towards us brought nice lightning show, heavy rainfalls and bit gusty winds (however not severe).

PS: Yes i know Armidale get lame tame storms characteristics!

Most of the Northern Tablelands fired yesterday but with the weak shear it didn't manage to progress far into lower terrain. A couple of cells did look severe on radar - one SW of Jackadgery and another just west of Macksville.
Locally a line of altocumulus castellanus was all that really reached here later afternoon. However a small thunderstorm did manage to form near Casino and spread NNE. I saw a few CGs and updraft lightning.
It was nice with the sunset colours but died by dusk.

Good photos there Michael! I saw that Casino cell was lonely and isolated before dusk.
Ok for today, generally thunderstorms overall likely for all regions including Northern Rivers, Mid North Coast, Upper Hunter and Northern Tablelands and possibly on the western slopes. Water vapour looking good from central western NSW producing moisture indicator. Armidale currently at 21.5 degrees and have some breeze which is a bit alot better than yesterday at this hour!
However i having a positioning issue for best spots for storms along NT's? I was thinking of Guyra or Ebor but this morning looks like West or South of Armidale according to the Vis and water vapour.

Hi All, we had a small storm fire up here yesterday. Convection started at around 11am and a small front moved over town at 3.30pm. Isolated rain from it but not anywhere near enough. There was tiny hail and the wind gust was nothing short of unbelievable. A couple of claps of thunder and a few CG'S, soon after dark it collapsed and was all over. I thought it might continue to Brisbane but the outflow seemed to stifle it.
The Storm turned on a colour show as the sun illuminated it at sunset.

I also witnessed that cell that developed north of casino. Witnessed some flashes but that is all. Today it is clear but specky cumulus developing and becoming visible on the latest VIS will most likely grow into cumulonimbus. Humidity today is high with Ballina right on 83% at the moment with a north-easterly and also 29C. Attached below is the instability map for tomorrow afternoon. Just look at that colour in there. Looks more costal to offshore.

Some scattered but small cells in all of northern rivers. There is not much more to happen today but we will see how the afternoon treats us.

Chased with Michael Bath and later meeting up with Rodney Wallbridge. Here's some pics from a less than spectacular chase out to Mallanganee. Most stuff that struggled to get going were moisture starved and low topped. But still nice to be out amongst it again and here that familiar sound of thunder again.
Early convection west of our position

This struggling cell managed to spit out two visible CGs and some thunder
(http://i238.photobucket.com/albums/ff315/jaypat75/24%20Oct%202009/IMG_7646.jpg)
A fair bit of virga was abundant today thanks to dry lower levels
(http://i238.photobucket.com/albums/ff315/jaypat75/24%20Oct%202009/IMG_7652.jpg)
Thanks to MB for picking me up as I'm carless for the next little while. Great to get out with NRs crew again.
Tomorrow looks a bit more promising than today but with a pretty saturated forecast sounding for 06z will this result in embedded thunder rather than discreet cells. Although there appears to be a hint of a dry slot in there but with these smoothed forecast soundings its hard to be completely sure of the accuracy of them. Time will tell I guess.
Heres the CAPE chart for tomorrow (00z run)

on Friday i went up to Karuah on the central coast , even the BOM models suggested that a moist NE wind would make it through to the ranges at least , but oh no it did not happen plus the storms were raining on their inflow (i thought that might happen but i could only chase that day). One storm was struggling to organise and had an interesting base breifly but moisture was only getting about 4 or 5 km inland. any way heres a couple of pix.
-
still cant put more than one pic up but heres a frame grab of lightning from the same storm

Once you put your post up with the one pic modify it and you'll be able to add the other pics in the one post ;) nice lightning pic ;D
Got to watch a few nice cells try to get going today (had a nice vantage point from the balcony at varsity towers facing the hills) saw a couple of CG's and a small crawler but that was about it nice to see some lightning though been a while lol got pics of one of the cells will post the pics whn i get home tomorrow

We had a repeat of Fridays activity only this time it was much bigger. The cell in the photos below although slow moving, grew considerably and at sunset it had formed an anvil near Allora. There were a few smaller cells around and again the same thing, small cumulus forming at around 11am.
I am hoping the last two days of activity is a build up for this afternoon or Monday storms. There is not a cloud in the sky at the moment.
ps...love all the photos but that lightning shot is pretty cool Nick.

Hey
Where do u guys think all the action is going to be today?
-
a boundary over sydneys suburbs has created backbuilding cells which are dumping rain , in the last half an hour i have had 42 mm in Marrickville (sydneys inner south west). no sign of them weakening yet , some lightning but not extravagent. good to pick out the boundary on doppler wind radar
-
Well I can’t say I know where exactly they will be today but recent cells southwest from Coolangatta have been forming so probably the border area again. Huge ocean cumulonimbus from here.
storm boy
-
Well it looks like I was right. A nice thunderstorm structure has been growing for a while now north of us (Ballina) causing a cell to pop up on the radar with specks of orange. The lightning tracker confirms cloud to ground strikes and some more convection developing to the west of us. Two more cells east of Tenterfield are developing now.
we also have a severe storm warning now

TOP PRIORITY FOR IMMEDIATE BROADCAST
SEVERE THUNDERSTORM WARNING
for LARGE HAILSTONES, FLASH FLOODING and DAMAGING WIND
For people in the
NORTHERN RIVERS and
MID NORTH COAST Forecast Districts.

Sydney rain event - 25 October 2009
There appears to have been a significant rain event across a portion of Sydney mainly within eastern Sydney. Rainfall for sunday to 4.30 pm has been light across Western Sydney with falls of 3 to 4 mm which is nothing significant. However when checking the rainfall figures for Sydney I note the following weather stations have recorded:-
Frenchs Forest - 65 mm, Canterbury - 54 mm, Marrickville Golf Club - 51 mm, Chatswood - 46 mm and Sydney Observatory Hill - 33 mm.
When checking the Sydney Observatory Hill weather station figures on Weatherzone, it is noted that at 11.30 am, 1 mm had fallen, 12 noon - 4.8 mm, 1 pm - 18 mm, 1.30 pm - 27 mm and 3 pm - 33 mm. It appears the event took place between 12 noon and 2 pm.
Being at Rouse Hill in North West Sydney at the time where rainfall was light, I was not aware of this event occurring and at no time did I see any thunderstorm clouds or dense clouds to the east producing this.
La Peruse in South East Sydney had only 8 mm so the intense falls appear to be localised and isolated across the city.

I was at Browns Plains today and between 12.30 and 1.15pm a beautiful cell built just to the east of us, it looked as if we were finally going to get some action and good photos but, as true to the weather pattern of late, it slid past and soon dissipated to everyones disappointment.

The cell that dropped hail on Nerang looked pretty nice from my high vantage point(3rd floor lol) at robina, some nice CG's from the storm but it didn't appear to last very long got a few drops of rain here from it but out at Nerang there was reports of hail 2cm in diameter. Pity my phone went flat otherwise i would have some pics of the cell it was very photogenic for a little while

I am posting the following in this thread even though the forecasted event goes past the 27Th of October. I believe their is a concern for the Central QLD town of Charleville and surrounding townships, with the BSCH model predicting heavy precipitation over the next 120 hours.
Charleville has a total accumulated amount of 300mm during this period. Although this has changed a often over the last few days, it still keeps coming back to the scenario that they are in for some very heavy rain over the following period of time.
As the rain begins to fall, by the 27Th of October, if the models are correct,(I say this due to the continual changing of the predictions of late), Charleville will have received 50mm of rain.
By the 28th of October a further 100mm, 29th October another 100 mm and 30th October 50mm more. ( 300mm, and as obviously this could more or less than 1st predicted)
As we would all be well aware of, Charleville has received many devastating floods in the past. With this amount of rain and the ground being very dry and hard, I believe there is a concern for flash flooding to occur.
Col
Late edit: Once again the models have drastically changed over the last 12 hours and all models are now showing that falls of around 75mm are expected in the Charleville region. It appears the 00Z charts on BSCH are over estimating the totals,while the 18Z charts are a more conservative figure, this now appears to be the trend that is occurring regularly and making very difficult to put faith in the system.

Storm warnings are still current and good they are. Just look at what Grafton is preparing for!

Interesting day here yesterday. Convection started forming early over Cunningham's Gap with monumental towers. Very little rain from any of the cells forming here yesterday. They reached anvil and dissapated as quickly as they formed. This shots are taken of a cell that reached anvil over Killarney and I haven't processed the image yet but wondering if anyone saw the cell near Legume? Looked huge with anvil spreading for many k's. I got a side shot of it but wondering if anyone else saw it. I'm guessing it was near Legume but could have been much further away, 40-50km maybe.

Hi Colin and all,
Those huge bullseye type rainfall totals usually mean the focus of thunderstorm activity but you rarely get as much as forecast. With the GFS model, the most reliable run is 12z, followed by the 00z run. The output from 18z and 06z are less reliable. Also, GFS continues to poorly forecast surface moisture and temps this season.
Chris, there were some explosive cells during the day but the moisture and shear profile meant they were going to be short-lived. There was a lot of CAPE available as illustrated in your photos. Here's my view (taken from home at McLeans Ridges) of the cell north of Wiangaree about 0630z (530pm EDT).

This is the earlier cell that moved along the Gold Coast hinterland (from about 0230z, 1.30pm EDT)

Others for 25 October here (http://australiasevereweather.com/photography/photos/2009/mb20091025.html)
Much stronger and sustained storms moved through the Mid North Coast and into the lower Northern Rivers into the evening.

25th October 2009
Gday All,
Well the last two days have been ones of frustration to say the least. So much potential only to be ruined by a lack of nice moisture. Yesterday looked like it had the potential to be an awesome day but again moisture let us down with most convection being high based and pulsey due to weakish shear.
After watching the radar and the sky I decided to make the decision to head out for a look and I made my way to Rods house around 130pm. There was some nice convection to the south which turned out to be the Dorrigo cell which had a nice radar signature for awhile. Not long after this a cell got its going on the Richmond Range and proceeded to make its way towards the Casino area. We could make out some base features albeit a tad unorganised but we decided what the hell and went for a look.
(http://i238.photobucket.com/albums/ff315/jaypat75/25%20Oct%202009/20092510_14.jpg)
It had a nice anvil going but after travelling around 25kms south of Casino it collapsed and we decided to head back to Rods house to wait and see what else would pop up. This would turn out to be a mistake because as soon as we got back we could see some strong convection powering up again to the south around the Nymboida area. There was some very impressive updrafts going up and it certainly was very photogenic. The timelapse I took should be very nice. It appeared to have a backshearing anvil but I think this wasn't the case as the upper winds weren't that strong and it seemed to just pulse continually in the one spot.
(http://i238.photobucket.com/albums/ff315/jaypat75/25%20Oct%202009/20092510_03.jpg)
This is the same cell that AC, Sercy and Andy were watching from Casino.
Whilst all this was happening strong convection had popped up to the north and Rod and I had to make a decision which way to go.
(http://i238.photobucket.com/albums/ff315/jaypat75/25%20Oct%202009/20092510_01.jpg)
We opted for the southern cell as it looked the stronger so we headed towards the Whiporie area. When we arrived we had a chaser convergence with AC and co. Again, frustratingly, the cell had lost all of its oomph and had all but died. After hanging around for about 1/2 an hour we decided that things weren't looking great so we made an executive decision to head back again and re-assess things at Rods house. Unfortunately Andy and his partner and his son had to head back home at this stage.
A quick radar check when we got back to Rods revealed that in fact some stuff had got its act together again to the south and distant lightning was visible from Rods house. It was showing some quite nice reflectivities on the radar so after much deliberation we all decided that heading towards Maclean might be the go. As per usual all the best lightning was occurring whilst in transit but eventually found a spot off the Pacific highway (old Pacific Hwy) and started snapping. There was some outstanding crawlers with a few nice CGs thrown in for good measure as well. Here are some of my favourites.
(http://i238.photobucket.com/albums/ff315/jaypat75/25%20Oct%202009/20092510_02.jpg)
(http://i238.photobucket.com/albums/ff315/jaypat75/25%20Oct%202009/20092510_17.jpg)
(http://i238.photobucket.com/albums/ff315/jaypat75/25%20Oct%202009/20092510_21.jpg)
After watching this for around 45mins Stratto Cu started to fill in from the south so we decided to head a bit further south then west to try and get a vantage point for some more stuff developing to the west. The Stratto Cu deck made for difficult photography so after about 20 mins we decided to call it a night. It had been a very long day and with another 1 1/2 hrs on the road left it seemed to be the best call, even if the lightning had started to increase in intensity as we left. I ended up finally crawling into bed at 215am, 12hrs after I decided to head out :o .
Considering how frustrating the day was was it was nice to finish it with some nice lightning shots and flashes accompanying us on the way home. Was great to catch up with AC, Sercy and Andy and I hope they enjoyed meeting the newest addition to the Storm Chasing community....Captain Supercell :laugh: whose true identity may be revealed at a later date. .
A special thanks goes to Rod who once again proved to me what herculean strengths of concentration he has to do all that driving. And thanks goes to Rods partner Sonya who was good enough to put up with us invading their house at 930pm.
Cheers Jason

Well it sure has been rainy also the pleasant sound of thunder has been heard over here for about 2hours now from the constant stationary cell east of us. A severe weather warning and flood watch are now current from a low developing northeast NSW area. The warning is
Priority
NSW SEVERE WEATHER WARNING
Local Flash Flooding,
For people in
Midnorth Coast, Northern Rivers
Issued at 3:20 pm on Monday 26 October 2009
Synoptic Situation: 3:00 pm EDT Monday
A trough lies over northeast NSW with a relatively weak, small scale low off the north coast. The low is expected to move to the west overnight, crossing the coast early Tuesday.
Local flooding is possible with thunderstorms this afternoon and evening but considered somewhat more likely overnight and tomorrow morning as the small low crosses the coast.
Emergency services advise do not enter flood water. Stay well clear of creeks, storm drains and causeways.
Now the flood watch
A low pressure trough over the northern parts of the state is expected to bring
showers, thunderstorms and rain to the northeastern and coastal parts of NSW.
Moderate to heavy rain is forecast for the Mid North Coast for Monday and
Tuesday.
Minor main river flooding is possible along the following river valleys, later
today (26/10/2009) and Tuesday (27/10/2009):
1. Orara River Valley
2. Bellinger River Valley
This Flood Watch means that people living or working along rivers and streams
must monitor the latest weather forecasts and warnings and be ready to move to
higher ground should flooding develop. Flood Warnings will be issued if Minor
Flood Level is expected to be exceeded at key sites along the main rivers for
which the Bureau of Meteorology provides a flood warning service. Across NSW,
about 70% of Flood Watches are followed by flooding.

Thanks for the explanation MB, appreciate it. Interesting to see the same storm from your side. This is the shot I mentioned earlier however I think the anvil in the distance is much further away than I first predicted. This is taken from Murrays Bridge (west of Killarney) looking south east in your direction at Wiangaree at 5pm est. Left side of the image, you can see part of the cell in the original cell behind Killarney. Even at 17mm wide angle I couldn't get them both in fame. Is it possible this is as far away as Casino and the same Anvil in Jason's photo?

Hi Chris,
Looking at that photo I would almost guarantee thats the same cell I got pics of. The structure looks pretty much identical to what I was seeing. Just a shame it all collapsed by the time we got down to that area where it was.
-
Following on from Jason, and just to clarify - my photo was taken from home: McLeans Ridges. Your photo does have the cell north of Wiangaree I could see and the one SW of Whiporie Jason and Rodney saw.

Thanks Jason and MB, that's a hell of a distance then! Jason, same thing happened to the cell behind Killarney (from my perspective) as MB explained. I wish I had made a pano now, get them both in. Next time! Thanks again fellas, was a great sight!!
Thankfully we have been getting steady rain since 3pm. The farmers will be happy!

Sydney Rainfall for 26 October 2009
Some areas of Sydney especially around Frenchs Forest and nearby Castle Cove had 114 and 112 mm of rain respectively for the period 9 am to 9 am 25 - 26 October 2009. The Frenchs Forest figure also includes the 65 mm that fell between 12 noon and 2 pm Sunday afternoon plus another 49 mm overnight.
Other big totals include 52 to 96 mm around the Sydney city area, 38 to 72 mm around the Sutherland region and some large falls around Hornsby. Falls of 38 to 49 mm fell around Blacktown.
The contrast between South West Sydney and Frenchs Forest is noteworthy. Only 5.4 mm fell at Camden and up to 16 mm around Campbelltown. The rain did not penetrate as well into South West Sydney as in other areas.
On the way to work early this morning, I drove through a flooded section of road at the intersection of Blacktown Road and Bungarribee Road Blacktown but that appears to have occurred from blocked drains and not from Blacktown Creek overtopping its bank. It was having an impact on traffic flows at this intersection.
The rainfall plot from the Bureau of Meteorology - Water and the Land site for 26/10/2009 provided shows graphically the uneven rainfall spread across Sydney for the period.

It's been raining steady here up till now Colin. It stopped half an hour ago but we were lucky to get a cell overhead with a downpour, few CG''s and thunder. Antonio, wish you were reporting for our region, top job mate! I love hearing about it all, you describe and report it in terms I understand, many thanks.

Well I do not know if anyone is getting annoyed with all of the updates on the flooding heavy rain and warnings but I like to keep people informed so enjoy.
It has been raining very heavy for a while now with lightning going off the charts just south from here (Ballina). It is also very windy now that the low has intensified. If you look at the satellite you can see the swirlage of the clouds.
Here is an update of the severe weather warning for us.

The heaviest falls have focused on the Bellingen area with totals around 400mm at a couple of places. The Orara, Bellinger and Nambucca rivers are in flood. That's the 5th flood event for the year at Bellingen and Octobers are not exactly renowned for floods!
72mm at my place (McLeans Ridges, NSW) most of which fell between 11pm and 2am. A number of convergence lines were evident and this meant narrow bands of heavy falls and some areas missing out. You can see it in the rainfall maps - especially seeing the lower Tweed getting light falls.
There was thunder and lightning around from late morning 26th until about 5am today - so about 18 hours of it around my location.

Over 29mm recorded here at UNE Armidale station. Wet enough to clean the dust off my car from previous dust storms! Now im happy to see rain again in greenage area this time of the year :)

Today I was working up towards Gosford (not quite that far) and had a nice view of some cloud buildup to the west of Sydney. When I got home about 4pm checked the radar and a cell west of Colo and tracking NNE had developed a nice black core before it fell apart about an hour later. Inaccesible country though if anyone had decided to chase it. There were also some smaller cells to the west and south but nothing really tracked over the Sydney area.
Also currently there is a severe storm warning out for parts of Queensland but nothing looks too heavy on radar at the moment from Warrego.
Still hoping Sydney will get it's turn this summer!

Managed to get another 35mm at home yesterday (28th) from scattered showers which has brought the household tanks back up to almost full. Finally ! :)

Goods good. Interesting to see Rous Water levels to hit 100% full soon too. It peaked at 87% last week and im sure it around 95% by now. Armidale managed to add extra 7mm overnight from some showers.
