Yay finally something to shiver over this winter as a cold blast will probly make it's presence felt over the country especailly by Sunday.
Snow could lower to low levls in the south and east of the south island iam not sure about the north island probly 6-700m I would think others?.
Something to graze apon anyway since the weather has rather

.
Thunderstorms in the west too coudl be minni tornadoes maybe as MS say 80-110kmh gusts with the storm or is that over estimating the will to spin

NORTH CANTY WHO WANTS SOME HIGH CLOUD TODAY?

Well I haven't looked into too much yet but as far as thunderstorms go it looks like the afternoon on Saturday is the day for us if we're going to get one! Here's hoping!

I can't see much of these gusty NW winds metservice are talking about, in inland areas perhaps but not here on the coast. Will be moderate NE winds easing on the day of possible storms, perhaps even tending southerly which would be a real treat and set off a convergence!

Cheers

Can't see too much getting up the East Coast at the weekend, the High/Ridge in the Tasman will be in the wrong position, needs to be further South for a good Wintry Blast.

I see Met Service say snow possible to low levels for the South and East of the South Island.

I'd usually disagree, but they actually got it right earlier this week.

Hi Aaron, I tend to agree with you on this

Looked very thundery towards the Alps this afternoon, was even picking up a few sferics.
Depends on timing and the activeness of the fronts moving up and across
In the long term, unfortunately, looking rather boring

...thats global warming for ya

after looking at the models I see a small risk of thunderstorms in south canterbury for saturday midday/early afternoon.

NZ Thunderstorm Soc · Fri 12/08/2005 17:55

May still happen

Keep thy fingers, toes and arse crossed so for the possibility?

....but methinks a fizzer

Very thundery looking along the Alps today

I'd say that they would of had a few claps/zaps in some areas over there

Looks like the West coast and far south will take the brunt of cold wet weather this weekend, maybe Canterbury might get something on Sunday, but it looks 50-50 with a southwesterly.
Already snow on the Lindis Pass, so the northwesterly flow atm seems to be colder than it feels here the east. (must be the same airmass that dumped low-level snow in SE Australia)

Wasnt a bad day today as the brief rain cleared early an the westerly wind was light and mainly fine and mild

Thunder · Unread post by **Thunder** » Fri 12/08/2005 22:31

Yes John, things just feel less likely for tomorow. But we'll keep f,l and a's crossed in anticapation!

The cold air is still coming over, will it be NW though? Here today it has gone NW but also ENE as times. There were 60 knot winds @ 500mb, tomorrow it's 25/30 knots so chances are it's less likely a NW will come through but surface winds in generall are showing to be the same so it could and in doing so rob us of moisture......oh well. Wait and see.

Cheers

Yes it is a fizzler now ohh well

iam still looking forward to storm season.

Seen those Journelists to the west last night taking photo's of Canterbury

yes some nice blinks of lightning to the west last night occasionally not as frequent as in summer but still something.
Looks to get thundery along the Alps today nice anvil clouds to west spreading eastwards to create high cloud wow

Tomoro there is a chance of something around midday, its not impressive but its the best situation we have had in a while and as metservice have on the thunderstorm forecast out of shore looks like the best place for these storms to fire up, bugger.

I'm heading up to the Ohau skifield right now, so I'll post some pics later. A lovely (albeit breezy) day in the Mackenzie.

Can see snow under the Cb in your photo Stormchaser, common with Cb's down South in Winter but uncommon up here around AK.

SI ski fields have had 20cm of snow (for most) over the last 24 hours

West/NW flow has meant most of the snow in recent days has fallen on the Fields close to the Divide, TrebleCone has done well while Mt Hutt has missed a lot of it.

I see hutt got only 5cm!!

Only a short period of showers in the early morning, otherwise it's been a fine day so far here, though certainly cooler than the last few days.
