and they tell me Spring is here ways downunder :(

Issued by our New Zealand Metservice:
A vigorous cold front is expected to reach the lower South Island by midnight tonight (Tuesday), then move rapidly north over the country during Wednesday. Strong to gale southerlies spread over the country behind this front, with snow to low levels about southern and eastern parts of the South Island and lower North Island.

Snow is expected to lower to 100 metres about Southland and southern parts of Otago during Wednesday morning, to 200 metres about Canterbury Wednesday afternoon, then to 100 metres about southern Marlborough (south of Ward) Wednesday evening.

This Watch is for the possibility that snow accumulations may approach warning amounts above 300 metres about Southland and southern parts of Otago during Wednesday, and about northern Canterbury (north of Waipara) and southern Marlborough (south of Ward) above 400 metres later Wednesday and early Thursday.

Snow is expected to lower to 500 metres about central parts of the North Island Wednesday evening, but to 400 metres about Taranaki.This Watch is for the possibility that snow accumulations may approach warning amounts above 800 metres about Taihape, Mt Taranaki, and the Hawkes Bay Ranges from Wednesday evening until Thursday afternoon.

Note, a severe wind warning is now in force for Wellington from Wednesday afternoon until Thursday morning. This Watch is for the possibility that southerly gales may rise to severe gale about Buller and northern Marlborough from Wednesday afternoon until Thursday morning, then about the Kapiti Coast, south Wairarapa Coast, Taranaki and Wanganui from Wednesday evening until Thursday morning.

In addition, there is a low confidence of heavy rain in northern Hawkes Bay and southern Gisborne on Thursday. (East Coast North Island) ( Thats where I live )

People are advised that snow is likely to affect the higher level roads and drivers are urged to exercise caution. In addition, bitterly, strong cold southerlies are likely to cause stress to vulnerable stock and make outdoor pursuits hazardous.

Considering all the warnings put in place for the last day or so regarding a 'vigorous cold front' spreading across New Zealand, I am surprised to see last nights temps as high as what they are.
Below is a list of backyard stations with a min temp of under 5°C since midnight.
Maybe they mean for this time of the year and yep I guess they are low :)

Arrowtown 0.6°C
Havelock North 0.7
Gisborne 0.9
Nuhaka 1.1
Frasertown 1.2
Castle Hill 1.3
Hunua 1.3
Waipukurau 1.4
Tokoroa North 1.5
Arthur's Pass 1.6
West Eyreton 1.6
Te Awamutu 1.9
Cambridge 2.0
Napier 2.2
Paraonui 2.3
Golden Bay 2.4
Wairoa 2.4
Cheviot 2.7
Te Puke 2.8
Darfield 2.9
Mahia Beach 3.0
Wairoa West 3.0
Blenheim 3.1
Te Anau 3.2
Port Levy 3.5
Russell 3.5
Mohaka 3.7
Massey 4.0
Winton 4.0
Reefton 4.1
Swannanoa 4.3
Howick 4.5
Grey Lynn 4.7
Mosgiel 4.7
Fairfield 4.8
Dargaville Airfield 4.9
Red Beach 4.9

and since you up there will have no idea where these places are, here is a link to our live map. Tonight I see again the temps dropping ( its Wednesday night )
http://www.localweather.net.nz/smf/new-zealand-local-weather-network/

and for tomorrow:
Southerly gales are expected to become severe overnight in parts of Marlborough, Wellington, Kapiti and Taranaki. The strongest winds are expected in the early hours of Thursday morning with gusts of 120 km/h in exposed places. Winds of this strength have the potential to damage insecure structures and make driving hazardous for high-sided vehicles and motorcycles.

In addition, snow is forecast to lower to about 200 metres in Marlborough south of Ward and Canterbury north of Waipara Wednesday evening, with heavy snow above about 400 metres. In some places a further 10-20cm could accumulate between 8pm Wednesday and 8am Thursday. Snow showers should ease during Thursday morning with the snow level lifting. People are advised that the biitterly cold blizzard-like conditions overnight are likely to cause stress to vulnerable stock and make driving hazardous.

and back to my fire for me :)

Yes correct. Much of Christchurch is still to be cleaned up.
Many trees down. West Melton had that 140km, very damaging.
Some suburbs went 3 to 5 days without power.

Friday night 20th September 6.00pm onwards.........

A sudden, severe thunderstorm has hit Wellington, causing problems for commuters heading home.
Surface flooding has been reported in some parts of the city, prompting the New Zealand Transport Agency to warn drivers to take care and drive to the conditions.
Some Tranz Metro train services have been delayed or cancelled, and flights in and out of Wellington Airport have been disrupted.

A central fire communications spokesman told NZ Newswire this evening about two dozen thunderstorm-related calls had come in between 6pm and 7pm.
Most were about surface flooding or fire alarms being set off in buildings in the central business district as a result of lightning.
Power outages have been reported in some parts of the city.
WeatherWatch says the thunderstorm band is moving up the lower North Island.

Yep we are about to fill our water tanks, well the rural districts are :)

From our metservice
A deep subtropical low approaching from the north is expected to lie over Northland Tuesday night, with rain and southeast gales spreading over most of the North Island and upper South Island.
The heaviest rain is likely to be about eastern Northland, the Coromandel Peninsula, Gisborne and parts of Hawkes Bay from Tuesday afternoon, and should ease in Northland and the Coromandel Peninsula Tuesday night. Expect 100mm of rain in these areas, but 150mm in the ranges of Gisborne through to early Wednesday morning. The rain is likely to continue through much of Wednesday morning in Hawkes Bay. People are advised that rivers and streams will rise rapidly, and slips and localised surface flooding are likely.

In addition, gale southeasterlies are expected to rise to severe gale in Northland, Auckland, the Coromandel Peninsula and eastern Waikato during Tuesday afternoon through to midnight Tuesday, with damaging gusts of 130 km/h. In Northland, the wind is expected to turn southwest Tuesday evening, and severe gales may persist through much of Wednesday. Winds of this strength are likely to bring down trees and powerlines, may cause damage to insecure structures, and make driving hazrdous, especially for motorcycles and high-sided vehicles.

A bit late but here is round up of the storm early this week.

From stuff.co.nz
Debris, flooding, and slips were left behind after stormy weather in the top of the North Island last night.

Over 250 calls were made to emergency services since yesterday afternoon and through the night with weather-related problems.

More than 80 calls were lodged with police, with most of them around 11pm because of the high tide in Auckland.

The lower part of the Rodney district, north of Auckland city, was particularly hard hit, and roading contractors were busy all night with slips, flooding, and debris left on the roads, said Inspector Steve Kose.

"We had in excess of 80 calls, with key areas the lower Rodney area, especially around Orewa and Whangaparaoa," he said.
"Coastal properties had been effected by the weather and tide - the high tide was at 11pm last night, and there were a number of properties along the beach front that were affected."
He said some houses had flooded lawns and others suffered erosion.
Police set up an emergency evacuation centre at Orewa Primary School, and did a door-to-door with Orewa residents telling them they could head there for safety, he said.

Rest of article here:
http://www.stuff.co.nz/national/9205888/Storm-leaves-trail-of-destruction

From Dominion Post
Southeasterly winds reached 92kmh in the hills above Wellington while the wet and wild weather hammering the country caused slips and flooding in Hawke’s Bay.
Hastings police said there were a lot of slips and flooding overnight in southeastern Hawke’s Bay near Waimarama.
MetService meteorologist Tristan Oakley said the ranges above Hawke’s Bay and Gisborne had up to 150mm of rain in the 24 hours till 6am while other parts of Hawke’s Bay got 85mm in the same time.
Around Wellington, rainfall reached 24.8mm on the Rimutaka Hill and 8.8mm at Kelburn and Wellington Airport.
Gusts reached 92kmh at Mt Kaukau and 84kmh at Kelburn early today.
Winds had dropped off by 6am but only slightly. The rain and wind was expected to stick around today.
Wairarapa had up to 70mm of rain in the past 24 hours.

From 3news.co.nz
Thousands in the North Island have spent the night without power as gale force winds and heavy rain pelted the north and eastern parts of the island.
The subtropical storm moved across the top of the country on Tuesday night, uprooting trees, bringing down powerlines and closing roads.
About 6600 Vector customers lost power overnight, but electricity has since been restored to all but 1200 of them.
Winds reached 110km/h overnight with over 175 emergency calls made to the fire service.
Most calls were about downed trees and power lines, with a small number about flooding and about five or six people reporting damage to their properties, a fire spokeswoman said.
