Really sorry to hear that Warren. Dogs make the most amazing friends, if only they lived longer. frown My dog is currently about 12 and a half so she is getting on in age. I know that the day she goes will be one of the saddest days of my life.

Yep.
That's sad [censored] Warren.
We have a dog as well and it's doing my head in because she is getting old and it will be tough when she passes away.
She is a pound saved dog which is what we always get, yet they don't seem to last as long. In our experience anyway.
I feel for you.
I love dogs. They are so sincere.

I have nothing but pound dogs, they deserve the rescue! He was 14, almost 15 disease and cancer free.

Nice little storm near Mittagong, back building into the wilderness, such is the life of an Illawarra chaser.

You could go along Wombeyan Caves Rd and turn onto Kells Creek Rd as an option but it is still mainly in the wilderness.

Towers have been looming over the Central Ranges here since sun up, it looks to be exploding and might be worth a chase.

What does everyone make of the following warning form the BOM in their Sydney Forecast today

Quote:
An Air Quality Alert for POOR air quality due to Ozone has been issued by NSW Health. Those with respiratory diseases such as asthma, should follow their action plan and use their relieving medication where necessary. If respiratory symptoms worsen, they should seek medical advice.


that coupled with the following published about an hour ago

http://www.smh.com.au/environment/weathe...109-gtojlj.html

Quote:
NSW Health has issued an air pollution alert as Sydney prepares to swelter through another summer day, warning that an increased level of ozone in the atmosphere is likely to affect residents with respiratory problems...... The Bureau of Meteorology's forecast states that NSW Health has issued an air quality alert for poor air quality in Sydney on Tuesday.

"Those with respiratory diseases such as asthma should follow their action plan and use their relieving medication where necessary. If respiratory symptoms worsen, they should seek medical advice," the alert states.

Ozone forms in the lower levels of the atmosphere on sunny days by chemical reactions between reactive organic gases and oxides of nitrogen, according to the NSW Office of Environment and Heritage.

It is not a pollutant in the upper atmosphere, where it absorbs harmful UV radiation, but when near the ground is one of the irritants in photochemical smog. Ozone forms more readily in summer and reaches its highest concentrations in the afternoon or early evening.

NSW Health said ozone can cause eye, nose, throat and lung irritations, coughing and shortness of breath, and may worsen chronic respiratory diseases such as asthma.


Increased level of ozone in the lower atmosphere?

Might there be some showers or storms with this and we end up with an event like Melbourne had last year, where 000's were admitted to hospital and there were numerous deaths attributed to the event?

I originally thought the Melbourne "thunderstorm asthma" was due to ozone but apparently it's due to really fine pollen that swells up and bursts. So I think it's unlikely to get worse in Sydney with a storm.

I did notice a really odd colour in the lower sky earlier this morning. It was cloudy overhead but to the south the sky was dull blue but near the horizon it was almost a brown colour. It's always a scene I associate with hot conditions but I didn't know it had anything to do with ozone.

Benn there done that. Ask Ping Tang about Wombeyan Caves Road. One of his favourites.

The Wombeyan Caves road is beautiful but don't go there in a Holden Commodore. Not quite like that episode of Top Gear where they crossed the Andes, but unless they've fixed the road in the last several years, it's really only for 4WDs.

It's overcast in Sydney, hopefully that helps with the ozone, but I think that the sun will make more appearances as the day goes on. Maybe it's the lack of wind that's exacerbating the problem. Hot days in Sydney are normally windy, plus regular sea breezes and Southerlies help clear out the gunk, especially from the East.

The first 25kms or so out of Mittagong is sealed, but after the first 5kms there are about 2 places where you can see the sky.

Both myself and Ping Tang were chasing the same night storm several years ago (at the time we did not know the other was chasing same storm), it was going berserk with lightning, we are talking a flash a second. But all you got was trees. When I did get a clearing the storm had passed northwards.

Yeah guys Wombeyan Caves Rd is nice, I go along some of it on most days going to work. But yes Steve the road is pretty sketchy when it turns to dirt just before the Bullio Tunnel.

Yes, the pebble beach that they drove on in Tierra Del Fuego was a bit more of a struggle than Wombeyan Caves Rd. That episode is my all time favourite on Top Gear. The scenery is so nice and it's funny how their cars handle the roads and then of course there's the ending at Ushuaia.

The Saturday and Sunday forecast for Newcastle has gone from:
90% 6-20mm both days
95% 3-10mm both days
To 80% 1-2mm and 60% 1-5mm.
I'm starting to lose faith.

Loc: Melbourne (Belgrave); Corryong...
Hey g’day gang! Sorry for my absence, as I’ve been very busy. But I’ve made it to Merimbula down on the NSW South Coast!

Backtracking on my Corryong reports, including low and high temperatures, and any recorded rainfall.

Here’s my report for Thursday January 5th, which proved to be a fantastic storm day across the Upper Murray! grin

Corryong Airport – low: 16.5°C; high: 31.7°C
Khancoban Airport – low: 12.7°C; high: 29.1°C

My fiancée and I left town around 11am and went for a drive over to the Cudgewa Bluff Falls in the Burrowa-Pine Mountain National Park, then over to Tintaldra and along the Murray River to Walwa and Jingellic, and finally ending up in Khancoban. We returned to Corryong around 6pm.

Skies were already ripe with instability as we left town, with convection initially developing towards the south (Lake Dartmouth, Omeo, Mount Hotham and Falls Creek). By midday, storms were firing over the entire Victorian High Country, but towers were exploding high over the mighty NSW Snowy Mountains as well! Temperatures across the Upper Murray were soaring quickly towards 32°C with humidity to boot!

During the drive from Jingellic to Khancoban after lunchtime, a MASSIVE multicell thunderstorm had powered up over Mount Kosciuszko and the headwaters of the Murray River, and this storm became my main focus for the next hour or so as it moved northwards! The cumulonimbus was towering to a good 40,000 feet, with the most vigorous updrafts breaching the tropopause, bright-white in the hot summer sun; the base was a dark, boiling, angry mess.

Just after 2pm, my fiancée and I reached Khancoban Pondage, but within 10 minutes the storm moved in! Heavy rain and possible hail were being dumped over the Swampy Plain River Valley to the south (it was extremely dark in that direction); thunder could be heard on average once every 15 seconds, and flashes of lightning could be seen. Although it collapsed and died before reaching Khancoban, a dark and ominous gust front with whale-mouths swept overhead, accompanied by a powerful blast of cooling, but howling gale-force winds that lasted about 5-10 minutes, lashing at the trees and making the lake-surface very choppy! The outflow sent all the people at the lake rushing for cover, but then it ended as quickly as it hit.

But the same outflow winds from that storm helped kick off a much more severe thunderstorm just to the west, over Corryong itself! The skies in that direction grew increasingly dark and threatening until the storm finally broke around 3pm. Khancoban only caught the eastern fringes of this cell (spitting rain and fairly gentle cooling winds), but thunder was quite frequent, on average 3-4 times per minute, at times almost overhead in the storm’s anvil! A few CC and intra-cloud flashes and even a couple of dangerous CG lightning strikes were observed to the west in the storm’s core.

According to reports from my parents who were back in Corryong at the time, the storm lasted about an hour in town, dumping intense rainfall and bringing frequent, dangerous lightning! And despite the severe thunderstorm warning that was in place at the time, no large hail resulted.

Back in Khancoban, the storm finally ended at 4pm and within 30 minutes the rain stopped and the Sun was back out, although further shower and thunderstorm activity was away in the distance, particularly behind the main Kosciuszko ridge and towards Albury/Wodonga. My fiancée and I went for a swim at local pool for over an hour.

At 5:30pm, we drove back to Corryong, arriving by 6pm. On radar, a new cluster of multicell thunderstorms was edging its way slowing north in our direction; several huge cumulonimbus towers could be seen to the south/southwest, with new convection continually going up ahead of them!

From around 6:30pm onwards, the sky to the south became very dark and boiling, contrasting beautifully with the sunlit foreground, while the top of the storms soared high overhead, finishing in one dull-grey anvil that spread off towards the east, with mammatus hanging down; the base of the nearest updrafts just south of town were wind-torn, with a bit of a shelf cloud developing (these updrafts helped kick up a new, fairly weak, separate storm cell that headed northwest towards Cudgewa, Walwa and Jingellic), and rain and hail being dumped in torrents in the distance. By 7pm, booming thunder could be heard in the distance (on average a few times a minute). Ten minutes later lightning was visible in the rapidly gathering darkness, and quickly began ramping up as the storm edged closer; the Sun vanished behind the impending storm around 7:15pm. Most of the lightning was just intracloud flashes, but a couple of CCs and a few potentially dangerous CGs were visible.

The thunderstorm’s shelfie swept north into Corryong just around 7:30pm, accompanied by cooling, blustery winds, light spitting rain and a wild, turbulent, at times tornadic sky. Alas, the main cell made a right-turn and swung towards Khancoban, weakening as it went along. By 8pm, after spitting out one final flash of lightning and clap of thunder, the storm ran out of steam and died. frown

But as the Sun went down, it caught the dying storm and created a beautiful double rainbow! The sunset itself, complete with anvil residue from other decayed storms to the west and southwest, was also magnificent. By nightfall, the show was over and a pleasant, starry evening followed. smile

While it was admittedly not the best storm day, as I never scored a direct-hit from any of the cells that developed, and steering was poor, it was a great storm day nonetheless. Plenty of instability and amazing convection, some good storm structure, the usual contrast between sunlit foreground and stormy darkness, blustery winds, lightning, and some very welcome heavy rainfall!

Khancoban Airport only scored 0.6mm of rain, as opposed to 10.6mm at the Corryong Airport (and 11mm in my private rain gauge). Only around 1-2mm was predicted for the Upper Murray on Thursday, so it just goes to show how erratic, localised, and intense the storms were.

A pity the Yarrawonga radar was out of action, so I was forced to rely on the Melbourne, Canberra, Wagga Wagga and Bairnsdale radars.

My report for Friday January 6th...

Corryong Airport – low: 13.1°C; high: 34.0°C; rainfall (24 hours to 9am): 10.6mm
Khancoban Airport – low: 12.4°C; high: 34.1°C; rainfall (24 hours to 9am): 0.6mm

Following a cool night, it was a hot, humid and partly cloudy day, with a nice cooling breeze to offset the intense mid-summer Sun. There was a bit of convection about the Upper Murray and nearby NSW Snowy Mountains, but no thunderstorms, only a few brief afternoon showers around Bombala on the Canberra radar. Otherwise, only other thing of note was a lovely sunset. smile

My report for Saturday January 7th...

Corryong Airport – low: 14.2°C; high: 34.0°C
Khancoban Airport – low: 14.9°C; high: 33.9°C

It was another hot, sticky day following a comfortable night. Sunshine was abundant, although from about lunchtime onwards high cloud began arriving from the west in response to an approaching low pressure trough. A pleasant breeze offset the unsettling heat. There were some juicy convective clouds about, but no showers or thunderstorms developed unfortunately. Only other thing worth mentioning was a beautiful sunset. smile

My report for Sunday January 8th...

Corryong Airport – low: 16.8°C; high: 32.3°C
Khancoban Airport – low: 15.6°C; high: 30.5°C

I was bracing myself for what was set to be a potential scorcher, with highs likely to top 36°C. Fortunately, the passage of the low pressure trough provided enough cloud cover to keep temperatures approximately five degrees cooler than forecast! smile

Still, it was an admittedly sticky day. But in spite of the humidity, the weather was pleasant enough for me and my fiancée to take an afternoon drive north across the Murray River to Tumbarumba. Conditions were made a little more comfortable due to a slight breeze, as well as Tumbarumba’s higher elevation compared to Corryong and Khancoban.

The tail-end of the trough brought clearing skies in time for sunset, but not before bringing a few light showers around 5pm. I witnessed no thunderstorms, but the trough brought some very unstable conditions, which I took as a promising sign for the following 24 hours (Monday January 9th). smile
