Victoria: Day to Day Weather Talk

[Supercellimpact]

Hopefully this high pressure ridge can go into the tasman. Will have to keep eye out tommorrow then won't I .

[droughtbreaker]

5.5C here this morning so it was definitely a cold one. Once the sun came out it didn't feel bad though. 19C at home for a maximum.

[norfolk]

Finally a beautiful summers day with light winds sun and warm temperatures....give me this and not all that rain any time!!!!

[droughtbreaker]

An active weekend ahead. Friday should see a late shower or two and possible storm, Saturday will be fairly showery, particularly on the ranges and coastal. Sunday will be a very unstable day, classic 'coldies' and widespread heavy showers on and south of the ranges. Remaining cool for a while after that too.

Hopefully that will stuff the locusts up for a while.

Melbournes rainfall for November has been upgraded again 2 weeks after the month ended its now offically 115.2mm up from 107.0mm which puts Melbourne at 746mm for the Year 30mm less than 1996 (776mm) 1995 Melbourne saw 803mm!

[Rhys_34]

Johnno do you know why the BOM does that after the month has ended? I would have thought the automatic reading of whatever rain fell in November would have been done straight away, where do they find these extra mm's?

[Jake Smethurst]

It's what they do with their quality control. When I was at the BoM, they showed me and actually got me to do a few.

They look at a station and compare it to sorrounding stations, depending on the difference between them, they may add several extra mm's or take away several mm's. Thats the best way I can explain it. They look for errors in data basically.

[Rhys_34]

From what you saw Power Storm would you be ultra-confident in the revised rainfall figures then for November?

[Jake Smethurst]

I personally don't think it is the best way to ammend rainfall data. I am sure that the BoM would not be able to exactly know how much a specific station in question received. But then again, it might be the most accurate way to do it for problem stations.

Maybe DJ can shed some light on this?

There may be a better place to post this (mods feel free to shift) but... big news from out west for those of us who follow these things - total Grampians storage is approaching 50%! http://www.gwmwater.org.au/index.php?op ... Itemid=131" onclick="window.open(this.href);return false;

Last time this happened was 1997. The rainfall deficit continues to contract.

[johnno]

Great news Gordon! Only week or 2 ago it was 41-42%

[Australis(Shell3155)]

lets hope their water quality will improve,
to shower in Horsham is like you just got out of a pool.
I know Mum was struggling with making a coffee from what come out of the tap.
50% is great news.

Another nice little update from today's MDBA report (my bolding):

"River Murray System inflows (excluding Menindee and Snowy inflows) for the month to date total
around 2,000 GL – which is already more than the previous highest December inflow on record of
1,830 GL in 1992. By the end of the month the total could exceed 3,000 GL (many times the long
term average of 418 GL) eclipsing the previous record by a significant margin.

Anyone seen this piece of stupidity? Once people start thinking with their brains instead of the rear ends you would be surprised how good this country could be.

SNOWY Hydro chief executive, Terry Charlton, recently confirmed that water was dumped into the already flooded Murray-Darling Basin, but said the authority had little choice (The Australian, December 15, 2010, page 7). A real time operational diagram, however, tells a very different story.

Last Wednesday, Snowy Hydro could have sent water into Eucumbene dam. At only 20 percent it had a storage capacity of a whopping 4 cubic kilometres of water.

Instead, the water managers set the trans-mountain tunnels so water was flowing away from Lake Eucumbene at over 80 cubic metres per second (6,912 megalitres for Wednesday).

Water was filling Talbingo and forcing releases from Jounama pondage into the already spilling Blowering Dam, threatening the township of Tumut and adding to the crisis along the Murrumbidgee River.

As if this wasn’t enough, the real time operational diagram for Wednesday December 8, 2010, shows that this water, drawn from Eucumbene, was also being used by Murray electricity generators pushing even more water directly into the Murray Darling Basin.

“Mr Charlton was incorrect in saying that generation was only from inflows below Eucumbene last Wednesday, although they were large at the time,” a source told me this morning.

“Why weren’t Mr Charlton’s water managers pushing the water back for storage into Eucumbene from the Tumut system,” he asked.

Tumut River residents were issued with urgent evacuation orders last Thursday after the increase in outflows.

Desperate farmers phoned Snowy Hydro last week asking why flood waters were being sent west, rather than east to Lake Eucumbene, given this dam was less than half full, but their calls were ignored.

The Snowy Mountains Scheme was built for the storage and diversion of water with hydropower generation as a by product.

Current and past employees claim that the current board and management are now driven almost exclusively by money.

“The management are setting the business up for sale when the NSW government changes next year,” said one source. “They want the balance sheet to look as good as possible so [we] are generating [power] like mad, even when electricity prices are low and irrespective of downstream impacts.”

Hows the warming going?





Might hit 25 this week, oh dear.

[Supercellimpact]

Then 29c christmas day. It would be nice if it stays below 30c for a few more weeks.

[Anthony Violi]

I would post yesterdays graph but someone must be sick, and they have not been updated. Thats the graph for Friday, and even yesterdays will look even better.
