The lift will be there today Tim by way of low level convergence. A convergence zone will develop down the centre of the Island. The main driver for todays instability is the hot afternoon temperatures coupled with modest moisture. Looking like CAPE values of 500j/kg won't be out of the question but it doesn't look like a storm chase set up. Will be watching all the same.

Cloudy warmish night here, low of 16C. I'll believe the 26C today when I see it

I know, MetService has an odd way of sending those temps through to us they include centres not on the daily list. Have asked about it but had no luck in finding out why!

I see that the clouds are actually coming in from the NE now...after originally coming in from the west

The transition from cloudy skies to blue skies was fast! 21.8C now and rising...hardly a breath of wind, DP 17

The cloud build up are starting and look to be further east than yesterdays,hopefully this is a good sign for later in the afternoon.

Overcast here so not much chance of any cloud build ups here this afternoon unless this cloud clears in the next hour. Currently sitting on 20 degrees with a current dew point of 16.

Getting warm around Hamilton atm, 27°C at the Hamilton AWS and 28°C here.

Summery here too, hit 25.1C before but don't think we'll reach 26C due to sea breezes. Only gusting about 13km/h but its enough to keep the temp down!

Fine an sunny here, some low cloud early this morning. Warm and 30.6 degrees.

A lovely day here in Auckland, clear skies, 26C, dewpoint 15C, no sea breeze at my house yet.

I see there are inland showers developing now over the NorthIsland high country, South Island is looking much more stable today.

Its been WSW this afternoon though light.Harsh sun,imagine it at the xmas parade.

32.2 now

^ I see MetService currently have Wanaka on 30.9C and Queenstown on 28.1C.

Max of 24.5C here.

CB top to the far south.

Is it true that Auckland's Airport power outage was because of lightning?
Was it that "Thundery" up there yesterday?

Can you get lightning out of stratocumulus ?

I think some jurno may have their wires crossed, so to speak. Lightning strikes have caused previous runway-light outages. A factor in last night's outage may have been the residual effects of previous strikes.

Still 25C here at 6pm, only dropped 0.5C below the day's maximum. How odd?
Might have something to do with the change in wind direction

the cloud cleared quickly as it reveresed, moved back in from the NE
but now is back moving in from the west...been moving back and forth!
can see that CB over taupo way and shows up well on sat pic and rain radar!

Got to 30C here this afternoon but any cloud build ups fizzled out during the afternoon but popped up in the Molesworth area though,neat to see the anvil heading west which ya don't see very often

The cloud top on that cell was around 12km! (height of the trop)

Nice photo Richard.

They were theorizing the height of the hector anvil at 70,000 ft (23km) yesterday.

wow, that was high.

Another hot one again coming up once the low cloud clears which it is already doing to the east of here,wonder if we get the third day in a row of 30+.
Just a wee bit cooler over night on 13C than previous mornings.

When you consider USA gets those cloud tops (23km) and its at the same lattitudes as NZ it shows how crazy the instability is over there.

Just had a quick flick through the long range models and nothing stands out. The farmers will have to hang on for rain. I see CAPE 800j/kg modeled for Waitomo on Wednesday so maybe a decent storm down there Wednesday pm.
