10pm obs are picking up rain at Rotorua airport
I'll wait for the 11pm obs on sky now too..

Convection tomorrow looks much more widespread tomorrow with Auckland getting a slice of the action too

Friday looks interesting too...

That's a nice Cb on the sat pics, hope there's some pics from someone?

Today was another non event down this way, not unstable enough? no tirgger? I'm not sure, perhaps not enough moisture at the surface I think would be a main factor.

Hopefully you guy's get some more stuff tomorrow, looking foward to hearing the reports.

I got quite a few pics.. cant believe how big it grew in the end...
It was an unusual storm for me in that there was a very high frequency of ligtning, but none was very large.. all short c-c as much as I could see..
anyway here is a quick selection before I go to bed

been a long but fun day!

Thanks for the reports on that storm Ricky. I like the photos, the last one which shows a gust front is outstanding.

The storm was triggered by convergence between a low level northerly (sea breeze induced) coming in from the the Bay of Plenty coast and a general southerly over land. I guess there is a slight risk of a repeat performance later today over the same area.

A very good set of photo's Ricki.
Probably the best set of Storm chase photo's we have had on the Forum.

Well done.

Ricki, I hope you dont mind but I have lightened your no.8 photo for perhaps a better look. It's a really great photo.

Great stuff ricky!

How long were you in and around the storms etc?

It was so cool how it came up real late in the day and all of a sudden "pop" and there's a big Cb.

Nice pics to.

Today looks more stable than yesterday. Hardly a cloud in the sky over Auckland at the moment.

Both the Rotorua district and east Otago are the regions of NZ most prone to summertime convective buildups. Otago has had an eventful season this year while Rotorua has been very stable.

1pm radar suggests some nice blue on the south taranaki coast which is interesting.

And as Steven stated, beaut of a day here, very hot and bugger all hapening in the sky

Can see more cloud buildups inland today. Photo below is looking toward the Bay of Plenty from MtEden.

Fine and HOT 30c in the great basin once again

Westerly breeze.

Not ruling out any convective showers just yet...

Manukau heads obs · Thu 10/02/2005 16:33

Brian, can you see the lightning from Manukau heads?!

Yup the lastest satellite image has the Cb from about Opape to Hick's Bay and another one 80km North

Can see those big Cb build ups from here but they way off and too distant to get a good photogragh.

Achten · Unread post by **Achten** » Thu 10/02/2005 18:21

Edited a pic showing the cb's along the East Coast ranges. The yellow cross is my location, there must be smaller ones popping up as I can see them from my place.

wish I was down there again today!! lol

that was a very abrupt stop to the lightning yesterday.. went from about one flash per second to nothing in about 5 minutes! and just as the sky was almost dark too, seemed to coincide with a much faster NW movement of the system

I notice there is a cu buildup to the north over Northland this evening as well.
