The Inaugural Autumnal Ground Cooler Watchers thread is here.

Keep in the bounds of weather.
Here's how La Nina is tracking from EC's POV

And a very noisy IOD outlook - bit early to 'cast just yet, I'd say. But does allude to neutral territory early-winter.

South Pole Polar Vortex is well on its way to more darker, colder places.

Coolish morning here in Sydney, fair bit of rain forecast for the coming days. Wouldn’t be surprised if a more mild version of last years floods in Penrith come out of the woods. I’m tipping that the dam will spill

I guess this thread will progressively get busier as the “stoke builds” towards Winter. Finished Summer at home with over 100mm the last 4 days.

Here is how it is around the mountain (NSW) this morning. Started out ok with decent visibility however now very misty with low cloud coming in. Quite the breeze and 12 degrees but wind chill making it feel cooler.

Looking towards the alpine from CP.

My cousin from England does a lot of hiking in the Lakes District and he loves our high country scenes like these.
@SMSkier are they still building the new paths around Charlottes ?
Wrong thread for this I suspect… And one of the forumites I think has a thread on this stuff. Some remaining track works might be impacted by todays poor weather? More rain here on the leeward so far with around 12 mm since 9:00 a.m.

Melbourne, Lockdown-i-stan .

Heavy rain on Saturday and 70 kph winds on Sunday are being forecasted by EC and BOM for Mt. Stirling this Sat. and Sunday respectively. I just need two clear mild days ( soon ) to do my supply drop up at Mt. No.3 Refuge hut in readiness for winter BC XC ski action and snow camping.

Looking like the LR potential for a winter system in the last week of March.

This window looks very interesting mainly because we look to see the eroding Tasman Easterlies. There's a chance of a 2-3 week period of 2-3 autumnal/winter frontal system between last week of March and first week or two of April IMO.

30mm and still raining lightly. Thredbo and Perisher totals not far off that. BOM upgrade for predicted rainfall tomorrow. Currently no wind and not cold but dogs reckon it’s drier and warmer here…..

I was
Ground Cooler at Thredbo with an overnight of zero. Got down to -0.8. Let it begin.

Out last night and up along the Alpine Way with friends for dinner. Came out and it was that light misty precipitation and very cool. Sent me looking at BOM and cams….LOL when I got home.

Still single figures locally with cloud and fog. Fireplace has been on most days in March. Trees definitely in Autumn mode.

Need a bit of sun here. It’s so wet underfoot.

EC Weeklies starting to show some 500mb interest at long range, last week of March:

EC this morning:

Mate…what model does The Weather Channel use? They have been showing something around that timeframe for several days - on the 15 day outlook so I understand that’s always a long way out. Has been showing temps slowly lowering at each daily update (Thredbo TS).

Regardless, nice to see a little something on the forecast.

Happy to be corrected, but much like Accuweather, they have their own aggregate model, kinda like BOM's OCF model.
Most of their data would be NWS/NOAA-based, but given the long range, they'd be drawing on a lot of EC's output which is what alerted me to it last week.

Surely you jest. mild weather as forecast.. Mild is a type of cheese used to predict the future weather in the 1600's
Mild temps? Mild something else? I didn't see where the mention of mild was.

Yes this is really funny, moisture, rain , milder than snow.. we don't want that, but they are models. not that useful , never referred to it inn the text.
Nidecker referenced warmer weather, ie milder than colder.

Oh yeah, my bad. Didn't realise there was a comment attached to the article. Although, it was hard to comprehend what you were saying anyway...

@POW Hungry do you think La Nina will still be in effect during the Southern Hemi winter season or will it die off during '22?
Yep, we've got a long way to go yet.
Gotta keep an eye on the Nino3.4 region below, it's still in a relatively strong position for La Nina.
Screen Shot 2022-03-24 at 6.37.46 pm.png


The reemergence of a new (upwelling) Kelvin wave in mid-Feb (see below) suggests we have at least another 4-6 weeks of committed La Nins signal. Effects of La Nina, on Aus region will be felt for several months to come IMO.

Even beyond that, there's a 50/50 chance of trifecta La Nina:

Kinda starting to look like the 1998-2001 epoch IMO.
