RAINING IN TORRENTS THUNDER AND LIGHTNING BOOMING NOW

Shepherds Valley WX · Sun 14/11/2004 22:30

Hye Brian, I just viewed your footage...I paused it on the 32sec mark at the time of the strike...mate that is awesome!!! The lightning was more inter cloud up here, but thats a truly aweome piece of work by your webcam and you!!

I also experienced a massive baro jump almost instantaneously....why is that????

Yes, plenty of lightning but much of the thunder distant here. The storm looks to have gone around me here. About 15mins of heavy rain.

i was real lucky ....there was lots of forks like that just out over the harbour east of us.....the rain had stopped here, at the time (8mm in a short period)....and I am thinking, man, i could get these on the web cam.....and so i set it rolling, standing outside.....and then kaboom, the best one of the whole evening as far as a fork went....!
i had some closer, but the rain blocked the view (i.e 6 seconds to the thunder)

barometer...i suppose you can think of it as a pressure release....i have seen active cb lines before that do that with the barometer...its like a big correction step took place....its like there was an earthquake to release the pressure difference form one side to the other....

Awsome stuff guys!! I watched the video Brian, its great the webcam managed to get a strike! I wounder where Steven W is??!! Probably out enjoying the storms!!! Where else!

Hehe John...

Looks good for us tomorrow, then it'll be our turn after the awsome night you guy's are having up there.

NZ Thunderstorm Soc · Sun 14/11/2004 22:45

Good reports you guys (It must be risky having your computers going tho')
...yes bloody Auckland getting the crop of thunderstorms again

Hope we do well tomorrow.
I don't know about the South Canterbury thunderstorms as reported on TV1 by that irrititating TV woman, tho'???
Steven Graham's Boltex showed TS more to the south and around Fioldland way

I didn't look thundery tho'
No mention of the EnE Gales here in ChCh today either on TV.
I think they were the strongest Ne we've had in ChCh for a while.

Looking at Metservice radar and also looking outside I am guessing that could be it for tonite. The stars are out up here and the wind has swung back to the NNW 338deg... looks to be a clearance behind the storm. baro now steady at 998.3Mb... what a couple of hours tho!!

Good luck to the mainlanders for there "turn' tommorow night....

front must have gone through winds dropped and more WNW now and thunder going south and east now

I wounder where Steven W is??!!

My internet connection was playing up. I couldn't get on line.

Weather has really cooled off here now with the thundery front now well out to the east.

Shepherds Valley WX · Sun 14/11/2004 23:01

Has anyone else been checking ricky's Auckland Lightning Detector? It shows a heap of strikes in the area right now....is anyone else seeing it like that? I am waiting outdoors to see, as it looks like any strikes would be in my area!! Or is there an accuracy ior calibration ssue with the Boltek?

ricky · Unread post by **ricky** » Sun 14/11/2004 23:07

I gave up trying to work out what it was doing.. just went mental! lol and things were getting way too interesting outside to be looking at the computer.. then all of a sudden it started giving sensible readings again.

Downdrafts - big vertical currents pushing air downwards around the perimeter of the CB increases the air pressure - literally, more air is being heaped on top of you, so the pressure rises. If the very centre of the storm passed over you you would probably see a correspnding drop in pressure (so long as the storm was still being fed from underneath - as it reaches maturity it starts to feed in air from higher levels). Remember, there is a lot happening in 3 dimensions inside a storm.

Shepherds Valley WX · Sun 14/11/2004 23:10

Fair to say it was a pretty exciting time outside Ricky... what do you think its picking up now? I thought that perhaps there were so many strikes that it possibly had a delay in processing all the data...the graphic showing now looks to be suitable for the height of the TS event an hour ago....

Yeah ... but who wants to looking at a computer screen when there are more important things going on outside?

This is wicked! Squally Thunderstorms present in Hamilton, HEAPS of crackles on the am radio, and it shows on the lightning detector!!! - Though its not picking up anything around Hamilton

Thundery heavy rain, squally NW, 19c

which one are you looking at? its showing solid activity moving down into the waikato here...

Shepherds Valley WX · Sun 14/11/2004 23:16

Thansk for the explanation Tony....I learn so much from you guys!! its amazing this weather watching!! The wife is off to bed and can't understand what all the fuss is about...meanwhile an hour ago I was racing outside with yelling " I have to get a intercloud strike on the camera"

She also cannot understand the addiction to watching the Weather Display software for hours on end!!!

Shepherds Valley WX · Sun 14/11/2004 23:18

The java one, Hamilton is just south of Tauranga, and its got old dots, yet its still storming

ricky · Unread post by **ricky** » Sun 14/11/2004 23:22

oh ok yep thats what I have here

did you get any photos there? I was so close, but as usual no.. as Steven said, didnt come directly over here, none of the usual skytower strikes, but did experience that same sudden pressure rise

Willoughby · Unread post by **Willoughby** » Sun 14/11/2004 23:25

Boom! The windows started shaking

No, no photos, I have a digital camera but I dont know how to take lightning photos with it

Thunder · Unread post by **Thunder** » Sun 14/11/2004 23:25

The detector seems to be doing a good Job, yes?

Lightning for sure if your in the path of it as the storm moves more southwards, heaps going off!! Perhaps the news will have some lightning action on tomorrow night?? Hope so!

Umm, good job new thunderstorm outlook!

Don't worry about that Foggy,
I have had trouble with my video camera in the past.
Just go out there and enjoy the show
