Victoria: Rain/Storm Event (Analysis) November 22-28 2010

[Supercellimpact]

With the growing interest of later next week, I have decided to create a thread. Very warm to hot temps before the trough, above 32 for Northern Vic , then a mix of rain and storms. We will get a good a Idea of rain amounts around Tuesday and Wednesday.

We are still a little far out yet to make any clear statements on what will occur. I'm hoping this trough provides more of a thundery event, with a wide area of VIC to experience vast storm development. Really hoping for a few decent thunderstorms down here in Metropolitan Melbourne. We had a few weak storms a few weeks ago, but it's been a while now since anything really decent had passed through. We came close a few weeks ago, but close isn't good enough.

Looks like the temperatures down in Melbourne will be around the low to middle 30's, and the humidity by the looks of the forecast synoptic charts look to be just as favorable. Like anything, the time will play a big role in where and of what strength the thunderstorms are. Latest Stormcast run for Thursday and Friday has good numbers for a wide area in a triangle expanding from Horsham to Echuca, then down to Melbourne, with LI's of -3 to -4 and CAPE values anywhere from 700-1400. The previous runs haven't really moved alot, and i'm thinking not much will change either. Friday looks like a better day with C areas highlighted with stronger values, in comparison to the Stronger numbers out W on the previous day.

To be honest, i don't know alot about the specifics of LI's and CAPE values, but i know they are significant for development and are basically the atmospheric conditions on that day, providing other factors fall into place. Anyway, my guess is many areas will see anywhere from 10-30 mm. Melbourne should see around 15-20 mm imo.

Im liking the look of Thursday for Bendigo good li's and cape. waiting for the next few runs to get a good idea.

Been keeping an eye on it. Hoping for a classic storms spreading from the west type situation to unfold.

Anyone around the Seymour area interested in a chase on Friday or Saturday if conditions persist, let me know. Free the whole weekend from 9am Fri until 9am Mon.

Stormcast - for what its worth - is showing 2pm - 5pm as the best storm conditions on Thurs / Fri for the western half of the state.

EC had 60mm down for here which is great.

[Harley34]

BOM going for "Isolated Thunderstorms later in the day" on Thursday and Friday respectively.

[Supercellimpact]

Latest storm cast is up in 1 hour, then I see if it's consistant with the previous runs.

This maybe the first cyclone threat for Queensland !

[Petros]

La Nina heaven.. the fortnightly Vic rain event remains on track! My humble take on things is for storms Fri/Sat followed by sig. rain event for Ytbd areas of Vic (our turn this time?).

Lets just hope for the mallee we can scrape out of this with nothing. Harvest os only just beginning for the Mallee and all of us up here need a year that has good return. A lot of NSW has been hit by rain which has downgraded the grain and lowers the price. The poor buggers have been looking forward to finally making some money to start getting back on track and the very thing that they needed won't stop and is now costing them money. Ah the sunburnt country eh? Gotta love it.

Must be extremely frustrating being a farmer or someone who relies on the land and rain for an income. But, the weather has always been dynamic, so it's not something you get in to without knowing the risks.

I think we will see a big storm outbreak on Thursday afternoon. At this stage for Friday I think there is a chance for isolated embedded activity but I see it as a very significant rain day with 8/8 cloud.

[Meso]

Thursday has an asterix on the calendar...that's about it at this stage...don't wanna jump the gun.

[Karl Lijnders]

And looking not as hot IMO but certainly much more like Singapore.

Expect US to return with falls of 200mm by tonight LOL!

[Petros]

The tail end of this sequence might end up as a massive ECL acc. to ACCESS/GFS!!

[Karl Lijnders]

Any low that forms in the secondary phase of the trough will most likely move back east to west across the state and become cradled. That could make things very very interesting! The east looks primed for a big event IMO but could easily spread statewide.

Anticipating around 50mm here this week.
