Low/NW flow ... 23th-25th Aug

[Vertigo]

is it moving northwest?

[jamie]

i cant tell. i can only just see it as i cant see that way... hope its moving towards the city. Of what i can see it looks good

[David]

its a battle of convergence! who knows where its going! it looks like the new cell to the SSE of me is going to the NNE, but the thunder came back some time ago and is getting rather loud again...
Only 1.6mm fell in the first cell that went over. The next one is so dark, and can see lightning forks from it!

[jamie]

5pm radar looks interesting. Quite a few red dots about the NI and even the odd purple dot. (i save the image then open it and zoom right in)
I seem to be getting a better view as time goes by so i suspect it might be moving this way.

[Manukau heads obs]

bit of a wall cloud viewable from here just south of mt wellington or theraabouts
my webcam animation shows it is drifting north
SSW wind here

[NZstorm]

I watched that cb go up over east Auckland, could see the CG's from Milford on the Northshore where I was working! It is still putting out lightning, considering going after a lightning photo.

[David]

Yes NZstorm, still a few loud bangs in the skies around me. Had a heavy shower with the cell just gone over (4mm now). No sign of any hail though.

Just another loud crack of thunder

[Achten]

Thunder here as well, not overhead more west of me. Nice display though.

[Manukau heads obs]

another overshooting top just gone up...will be great if it stays active until it gets dark
I saw a bolt from way over here too

[Manukau heads obs]

not much lightning happening...but the CB further south in the north waikato I have seen a few flashes from

[Vertigo]

went to one tree hill rather than chase it, as it was moving at a snails pace

saw a very nice wall cloud on its south-western side, and shortly after, a rain core started dumping out of it. behind that i started to make out a funnel cloud. wasnt big at first, but quickly developed, and almost became a tornado from the looks of it! fortunately (or un- ), it weakened and disappated. if it had held out a little longer, it would have developed over the water, and who knows what it would have done! (i desperately need a camera).

multiple CG strikes, but lightning ceased after about 5:40. twas a multicell storm, youre right brian, the second was getting going as i left. if we have a nnw flow at the moment, we might get more through the night, fingers crossed.

[Manukau heads obs]

cool on the wall cloud/funnel cloud...I could see it looked good from way over this side of the harbour
hopefully someone got a photo of it

[NZstorm]

Air looks unstable again tomorrow but with a weak SW flow.

Photo here of building thunderhead to SE of Auckland mid afternoon taken from up on the North Shore.

[jamie]

Hmmm just saw a flash... strange that things are still active this late.

[Willoughby]

GREAT Photo there Steven I've noticed these setups are quite favourable in late August.

I just wish I had my camera on me this evening! Had a beautiful strong Cb develop just to the east of here just before dusk, nice solid round base and even had a green tinge in the cell, something you don't often see in NZ. And it kept on towering too past dusk.

Got to 18C here today.

Yes Steven, looks like the low level moisture will stick around into tomorrow - certainly a high risk of thunderstorms over Northern Waikato based on the 06Z run of the GFS. I'll have my camera ready!

[Vertigo]

very overcast today, seems we have a localised cloud layer. the rain radar seems to indicate the presence of a weak meso-low?

[Manukau heads obs]

yes, bit of low moved up past us this morning (a few showers here), rain radar showed nicely the rotating rain bands
i think possibly mt taranaki/cook straight might be set off the rotation?

[Willoughby]

Lots of Cb's about today just ashame they are a bit cold-looking unlike yesterday.

1.18pm looking west


2.00pm, looking west again, new Cb

[NZstorm]

Nice pics Foggy. Some weak cb's about Auckland today. There has been some lightning around Rotorua/BOP way this afternoon.

[tgsnoopy]

A couple of active showers this afternoon. One about 1pm in Tauranga and another about 3.30pm at Papamoa.

Pea sized hail with the 1pm one.

No complaints from me.

[Vertigo]

sundays looking like a cracker day in the park to me.

[tgsnoopy]

Saturday in Brisbane is looking good for River Fire

[David]

Looking good for Auckland University open day this saturday (starting there 2009)
Last thing I want is to get rained on.

[Manukau heads obs]

going by the nice grouping by my boltec, there has been an active CB over the Kaimas/south waikato area by the looks....
(weakened now)
shows up well on the sat image ...and on the new plymouth rain radar (better than it does from the auckland one)

[ricky]

Looking good for Auckland University open day this saturday (starting there 2009)
Last thing I want is to get rained on.

I wonder if the Atmospeheric Physics students will be there again with the mobile rain radar? that would be an interesting paper or two...
