went to bed, bumped my head, and got up and it was raining!

Graeme, excellent photos, well done.
I would like to know the total lightning count for northern NZ last night.
The static on the am band was continuous for about four hours.
Central Auckland got the best part of the storm between 1am and 2am with lots of forked lightning through the sky and the sky Tower looked to be hit a few times. I took some lightning photos on my SLR bulb, so pics still in the camera. But I was to disorganised, my camera got wet, so I feel I missed out on good photos.
I expect a few new thunderstorms to develop over northern NZ this afternoon with hail and very strong wind gusts possible in the storms.
Currently partly cloudy in central Ak with 17C and adjacent cloud building.

I first heard about those northern storms on the radio news this morning - they were the first item. It rained here overnight (from sometime after midnight, after I'd gone to sleep) and at first this morning, but it soon cleared up. Now it's sunny, with only scattered clouds in Chch, but certainly alot colder than yesterday.

From roughly 10pm through to 2am the frequency of the visable lightning in my location was on average 1 every 30 seconds. Nearly 500 just for me! The view from here would cover from the Waitakeres through to Kaipara so thats a fair amount of area.NZstorm wrote:I would like to know the total lightning count for northern NZ last night.

Hi you lucky people up north.
So, you had a 'feast' overnight !
I was picking up continuous distant sfrerics between 11pm when I got home and they were still going strong when I went to bed just before midnight. They were very very distant tho', I wonder if they were from those storm?
Good pictures Graeme, very NZTS potential shots!!
As Ben said ,it rained overnight with quite strong southerlies blowing with 9.5mm of rain here overnight before clearing up this morning.
Nice and fine now and becoming mild again. Very light SW

Yes they probably were AM travels huge distances due to the ionosphere skywave at night I was trying to get Magic 693 last night and the lightning in addition to the usual interference was wiping it out

Only scattered high cloud persisted in the Chch/Banks Peninsula area today, though I could see thicker cloud persisting well to the north. (Kaikoura possibly still wet) The cold southerly overnight did leave a legacy of a fresh dusting of snow on the tops of Banks Peninsula (melted by midafternoon) and on the foothills. I was at Amberley around middday and early afternoon, and there was a white coating on nearby Mt Grey down to about 700-800 metres.

WILL DO!
I saw that forcast, what does your opinion say John? You know best!
I remember metservice forcasting thunderstorms once and the day was a brilliant sunny one (brilliant because it was winter and we hadn't had one in a while), you posted a message saying " I feel sorry for all the thunderstorm damage etc people got", obviously you were being sarcastic, it was funny!!
Cheers

Brian, thanks for posting the lightning chart.
Something I have learnt from years of watching thunderstorms is that the cloud to ground strikes occur during the developmental stage of a cumulonimbus. The anvil crawlers(other end of lightning spectrum) come on the declining phase of the cumulonimbus. Anvil crawlers are a form of cloud to cloud lightning.
The storm line was at its peak developmental phase along the west coast, hence all those CG's and declining as it moved eastward hense less CG's. And I had noticed that the storm line had really weakened by the time it got out to sea east of the NI.

I agree Steven. There was nothing here the would stimilate thunderstorm growth this afternoon. NW Arch for most of the afternnon with thick As forms although I did notice virga trails along the Arch plus other forms of instability ie. mammatus and some glaciated cirrus.
I hope Aaron wasn't hopeful/disappointed !!!!

Hi John
Yes I noticed those forms in the NW arch. I wasn't dissapointed that much, my thunderstorm senses just seemed to tell me nothing was going to happen so I'm cool, hehe.
Does anyone here think that South Island West coast thunderstorms would be good to view, for some reason I've always figured they would be a whole lot of sheet lightning, don't know why?
Cheers
