It lingers in the Tasman til at least Thurs on today's weatherzone charts.
It looks like the cut off low and Invest 95P (that is currently progged to become a TC and move south) together create a lot of moisture for already saturated NZ after Ex Debbie flooding.
Going to be a wild ol day on the coast and up the hill for sure .
Fantastic , got to go to Myrtleford on Sunday for a game. Might just blow off the game and keep on going to Falls or Hotham with my trusty rockcrackers
I am still seeing 10cm above 1800m for Sunday through to early Monday. Snow down to ~1300m at times.
Rain after daybreak/mid morning Monday for the alps IMO.
Boyo, it looks wet, windy and wintery for Gippsland to the NSW Sou-Coast from Monday/Tuesday AM.
Rain on the coast may have a sting in it.
Yr Hotham has snow starting in the Morning, BOM about 1pm and WZ 9pm... wonder which one is correct? Will be there tomo
EC is still around 15cm for Main Range.
GFS is around 25cm.
I would say Midday for Buller and Baw Baw.
2pm for Falls and Hotham and Lake Mountain
5pm for Main Range
6pm for NSW resorts
Yr.no is comfortably 40cm for mt P
It's nice that not everyone around here forgets LM
I think below 1800m will see a lot of rain Monday, enough to wipe any evidence of snow IMO.
Main Range/Mt Perisher will get a fair bit though, it's just the quick fluctuations in FL that will determine how much stays on the ground.
I wouldnt be sueprised by upwards of 30 cm falling ....it just wont get the chance to hang around.. tbe precipitation volumes arent the problem. It is where and more inportantly the duration of the FL.
To me this system will be more interesting in what it,
may do when it enters the tasman.
Did someone say relative vorticity ? This one likes to fight decay.
You are talking in a lingo i like
100%! Some beautiful inflow. A couple of touch downs perhaps?
Ripper rain system for all of southern victoria.
Tropical mix with arctic
Anything could happen

SEVERE WEATHER WARNING
for DAMAGING WINDS and HEAVY RAINFALL
For people in the Central, North Central and parts of the East Gippsland, South West, North East and West and South Gippsland Forecast Districts.
Issued at 2:32 pm Saturday, 8 April 2017.
A strong cold front is expected to cross the State on Sunday with an associated low pressure system forming over Bass Strait during Sunday afternoon.
DAMAGING WINDS, averaging 50 to 60 km/hr with peak gusts to 90 km/h are possible about Alpine areas (above 1200 metres) of the Northeast, West and South Gippsland and East Gippsland early Sunday morning, easing by late morning.
DAMAGING WINDS, averaging 60 to 70 km/h with peak gusts to 110 km/h are likely to develop across southeastern parts of the Southwest district during the morning and extend to the Central and North Central districts during the afternoon and evening. Winds are expected to ease overnight Sunday into Monday.
HEAVY RAIN which may lead to FLASH FLOODING is possible across southeastern parts of the Southwest district, and the Central and North Central districts during Sunday afternoon and evening.
24 hour totals of 40 to 60mm are possible over the Central and North Central districts, particularly in the east. Isolated higher falls of 60-80mm are possible across the ranges. Rainfall is expected to contract to eastern Victoria overnight Sunday into Monday.
Locations which may be affected include Falls Creek, Kyneton, Ballarat, Geelong, Melbourne and Bacchus Marsh.
GFS 00Z has -16-18F in the cold cell @ 2metres,
One would expect the model would have been
plugged with the data from the bight this late
into the game.
Such a big anomaly points to a big shift in seasons so early. Some big anomolies around the pole too. -30F to +14F within a few hundred kms it seems!? Extraordinary SSTAs?
00z run shows plenty of stall well into Monday arvo.
Temps seem cooler at this time than expected? If morning warming doesn't affect things too much may see snow sooner than expected.. thoughts
Not for me they don't. The only factor influencing 'earlier' snow is winds, which for the most part remains to be seen @850mb. IMO snow for somewhere like Hotham (~1800m) snow is due around 1-3pm tomorrow - If I was to be a betting man, I would say ~2:30pm.
Something you don't see very often here in Melbourne.
Sunday 9 April
Showers, tending to areas of rain over southern and mountain areas with some heavy falls developing during the afternoon and evening. Isolated thunderstorms. Snowfalls down to 1200 metres Sunday evening. Mild in the east at first with fresh northerly winds. Colder, fresh to strong and gusty southwesterly winds extending across the State during the day and reaching gale to storm force along parts of the coast and ranges.
...and looks to be coming right up through The Rip
Tomorrow nights 9:30pm Spirit of Tasmania sailing promises to be a "chunder express"!
Thanks POW_hungry for the response, totally appreciate it. I should be there at 2:30 with a grin on me face
On satellite the trough looks not to far off from kinking (tear off) detach from the meridional flow and ride the jetstream. Also has a nice dry slot
Funky up at 500 - that cloud mass counter rotation
counter rotation over Perth way
I predict i will be cold working outdoors in Orange tomorrow.

Well we survived the weekend. Lake Tabourie was sitting in a sweet spot and missed the majority of the rain and the wind. Each band of weather that cam over on Sunday had a split in it right above us. Only had a few mm of rain at most. The peak gust recorded at Ulladulla was close to 40km from the SW. I was checking all weather forecasts and BOM had a severe weather warning for Gale force winds and Willy Weather was predicting near gale winds Tuesday Morning. We made an executive decision and packed up on Monday and moved into a cabin and waited for the end of the world but it never happened. The southerly picked up Tuesday afternoon but nothing extreme. All in all it was a great weekend, we told the kids we were packing up and going home on Monday. We drove off the campsite, camper trailer attached and then pulled into the cabin carpark and they were stoked, we hardly ever stay in a cabin.
Was thinking of you as it went both sides of us on Monday.
Worst of it went straight East and well to the South .
The other band went around the back and circulated North .
All the models and forecasts where looking like a pretty significant system and we're right in the firing line.
We got lucky here this time the eye seemed almost directly on top of us.
Stoked you guys got to enjoy the Coast at / near it's best.
Onya mate, nice one.
Peak gust through Ulladulla was actually much higher at 34kts (avg winds 20 kts) on early on Tuesday AM. Which puts gusts in the Gale warning category, but you're right it was mainly in the storm wind warning range. Offshore would've be drastically different though.
Glad you made a good camping trip away, nonetheless.
