Some cu's starting to tower here as well, light southerly breeze. Potential for hail here if it happens today.
Well keep you posted.

Convection started from clear skies at 9am and is 4/8 now with building, towering Cu. Cu looks like it's really 'activating' to the southeast at the moment.

18c, light southerly. :D

Possible late evening shower in Auckland this evening- southwesterly becoming gusty up there, afternoon convective showers from the Bombay's southwards inland

Its 18C, fine here. Can see t/cu inland. Should see Isolated afternoon thunderstorms over the inland ranges late this afternoon. Nothing in the Waikato though foggy. Won't be the heat or humidity there today, required for thunderstorms although isolated showers possible. Will be a fine dry afternoon for Auckland.

Some T/Cu turning to Cb now here

edit: yes NZstorm, a lack of moisture and cooling aloft.

Cb has nicely developed to the SE, height to 8000m?

Midday satellite shows a cb/thunderstorm over the Gisborne region.
The coldest upper air is in that direction hence not suprising.

Some reasonable Cu going up on the foothills here but nothing (at this point) to get too excited about. I'm not liking the NE breeze we have at the moment, it's a little more breeze than I'd like keeping temps down a little.

Some bigger Cu congestus type towers further north (Culverdon?) which look better.

Hopefully a thunderstorm or two up north today. Yes NZstorm, that eastern area of the North Island does seem to be favoured for thunderstorms today.



Cheers

Cb's around me, esp to the east. Jury is still out. They look good one moment then shabby the next. NZ Storm and others, when you talk about availability of moisture are you making a gut feel call or is this using info from soundings?. I would have though that the front yesterday that stalled and dissipaited over the North Island may have left enough residual moisture. Is that what we are seeing today?

Not far from here, 25km or so around Cambridge delivering heavy showers there as I type.

Huge mother of a cumuloninbus has popped up 120km away S towards Taumarunui, will get pic up shortly.

Mostly cloudy and warmest centre atm, 22c with light variable winds.
Cu congestus to the west and north and east great T/Cu to the south, taking more pics!! \:D/

Cu to north has got bigger and looks good. Cu on plains has got a bit bigger but is being capped, it needs a little more umphh to get through it (i.e. temp, convergence etc).

There's a bit of low level scattered cloud in the pic below.

Edit: Hmm, even though I do see signs off some sort of capping on the foothills it does seem more unstable than other day's recently. I note some strong looking Cu congestus over Oxford at the moment. Hopfully something happens!

Hi folks,

Thanks for your welcome the other day.

Looks like the convective forecasts are working out so far this afternoon.

Sprinkling of lightning on the detector over the NI. I see we are getting storms in the Bay of Plenty area now. This area was pegged as severe today.

Anvil now to the north of Wellington over the Tararuas, should fire soon with trof approching from the top of the SI.

I see there is a flash over North Cny.

Cheers

Paul

Paul, the convective forcasts have been one of the best additions to the Met service.

Short thunderstorm West of Hastings city about 1:30. Heavy downpour with small hail.

The big Cu near Culverdon has gone to Cb! Finally, a proper Cb round these parts! Bugger I have to work though, lol.

Cheers

Great. That ties in with a strike at that time. Good to get hail reports.

Thanks.

That Waikato Cb looks pretty good, even from approx 140km away - pic below. There are some good looking buildups over towards the Coromandel as well.

"Fists" going up this afternoon in inland areas. Glad you photographed them Aaron as there is lots of stratus moving in from the NE obscuring them from view here.
Seems to be Cb development to the north of here (Radar show shower activity possibly around the Waikari/Culverden area?)
A few weak sferics from about 3:50pm so possible lightning there ( haven't checked SG's lightning tracker yet)

Yes CB north of here Culverdon way alright Aaron cant get much of photo at the moment low cloud is cleared from here but there's that annoying alstratus in the way with just heads poking through.
Got a pic b4 after got off the bus and just to note Some CU going up to SW now perhaps Rakia area Aaron? here's hoping that develops into something soon.
Cheers
JASON.

Looks to be a strong cb/thunderstorm in the vicinity of the Kaimai ranges at the moment. Stands out clearly from here in Auckland. Matamata would be a good spot to see this buildup. :)

Yes, interesting to see the cb pop up over the Mt Pirongia area this afternoon. I wouldn't have picked a cb development there today. It looked great when it first developed but didn't last long and looked to dissapate as quickly as it formed. Mt Pirongia area is a great spot for afternoon convection.
