Northwesterly storm 10-12/08/07

[Gary Roberts]

Yep, a bit of lightning over the divide last night. We got some rain and much of the snow that was evident before it is now gone. I'd say Lake Ohau's season is almost done for. Good to hear the more southern fields got some. They've had absolutely bugger-all this season. People were saying Ohau had the best conditions and even they were scratching to keep it going, so I'd hate to think how crappy the fields were down Central way. Oh well, at least a bunch of skiers were unhappy, that's the main thing.

A few flashes of lightening again last night towards the Alps,heres a mid day report from Sunny Rolly,Baro 987 and steady,temp 14.9 c, dew point 3.0c,RH 46%.Wind North Westerly tending North Easterly 6.5 kph with Gusts around 10-15kph.

[gllitz]

Almost 19C here in Burwood...once the high cloud burn off, watch out!
LOVELY day!

[Lawrence]

Wind picking up in Rolleston now, getting quite gusty. baro falling 985mb

[gopolks]

Nice and warm, over 20 degrees in thisd part of chch, not much wind at all, barometer at 990.

[Storm Struck]

Strong gusty westerly here now not quite gale force yet though, clouds closing in from the west too.
Up to 19C here before, looks like a few thunderstorms in the mix of the heavy rain on the coast at the moment.
Could be the odd clap of thunder tomorrow late afternoon/evening along the windchange with heavy showers or hail .
Cheers
Jason.

Well, very odd. Yesterday Ohau skifield was closed because of high winds and heavy rain. Today they say they are closed because of "heavy snowfalls". Whichever direction I look I see bare landscape where snow had been before the rain and winds. I suppose it's possible they experienced some unusual localised weather.

[Lawrence]

Clouding over from the west nicly now,baro still falling 983 mb, 15.5c dew point 4.0c,RH 43% and rising,wind has been gusty but not that bad,still North Westerly.

After a nice warm morning temp up to 14 degrees at noon have dropped down to 4 with wind and rain.

[Snowlover]

I see metservice is forecasting snow for canterbury high country for monday with a free air freezing level of 400m. Isn't that almost snow to sea level when its that low?

[tidd66]

Down to 3 degrees now and a bit of heavy sleet.

[tich]

Down to 3 degrees now and a bit of heavy sleet.

Looks like some undercutting by cold air in the far south - snow forecast to 300m tomorrow; probably already down to that level.
Cooling down abit in Chch with the cloud, but still in the mid teens.

[Lawrence]

Just finnished looking at data and it looks like it's going to be really cold on Monday.Not sure about snow to low levels yet though, but we will all have to see in about 12 hours time what the situation is. 15c here and baro still falling slowly at 983mb

[kiwisk8er]

Wind just turned SW and now rain.

[mikestormchaser]

Interesting too hear about the sleet report down there, while its still mostly fine here in Christchurch, warm with NW breeze.
Might just geta bit of snow yet by how things could turn out haha

[NZ Thunderstorm Soc]

Very strong NW here at West Melton. Gusts up to gale force. Blew over my Stevenson's Screen!
Thankgoodness the instuments weren't damaged.
Wind seemed to die down now. I just tapped the barometer and it went down.

Can hear rumblings of Thunder just to the North West from here right now...

And the last bang just now was right here... Signing off...

[GreggWard]

I too have heard thunder coming from the W/SW. Looking very very dark down your way Spike_01.

Just had a look at the Oxford weather station: http://www.wunderground.com/weatherstat ... =INORTHCA3
Check out the wind speeds since 5pm!!

[Lawrence]

Clearing from the North now ,can see cloud all along the Alps,see picture,looking cloudy to the south as the front moves up,baro now 982 and still falling,wind mainly Northly to North Eastly but veering NW during gusts 6.5kph.Would not take to much notice of the wind as theres a tree in the way when its a N-NW blowing and anyway its not the recommended 10m in the air

[melja]

huge winds here in rangiora now.

[tidd66]

Has cleared up in Gore now might even get a frost if it stays like this.

[NZ Thunderstorm Soc]

Nice rain band to the west, tonight, when returning back up Hoskyns road from shopping at Rolleston.
Expecting some flashes in the Alps this evening but haven't seen any so far.
The cold front lies from Hokitika to Timaru at about 8pm tonight. Unfortunately, things look likely to be winding down
Shouldn't be much when the southerly comes through tomorrow but it should become cold and frosty when the 1040hPa anticyclone moves over us next week
It will be either anticyclonic gloom with the 1040, or just fine and clear
